Resumen

By accepting that an ageing body and its memories are simply a conglomerate of materials moving from one state to another and that drawing materials can be thought of as operating in parallel to this acceptance, drawings are made that can be read as visualizations of the ageing process. The experience of the ‘self-feeling’ of ageing is entangled with Deleuze’s idea of ‘the fold’ in order to develop a personal understanding of how one’s own thought can be taken ‘into’ the thought of another and how a conversation can enter the mind of others as a material entanglement.

Resumen

Research reported here addresses the issue of the reliability of retrospective reports of children's perceptions of maternal acceptance-rejection as measured by the Parental Acceptance-Rejection Questionnaire. A sample of 49 middle-class Caucasian 7- to 11-yr.-old children were asked to respond to the questionnaire reflecting on their mothers' current accepting-rejecting behaviors. Seven years later the same children—now adolescents—responded to the same questionnaire with the instruction to reflect back on their mothers' behavior when the youth were about 7 to 11 years of age. None of these youth recalled having been tested seven years earlier. A simple zero-order correlation between scores in childhood and adolescence was .62, indicating that adolescents' retrospective recollections were in moderate agreement with their reports during childhood. Thus, it seems clear that, at least with respect to perceptions of maternal acceptance-rejection as measured by the Parental Acceptance-Rejection Questionnaire, researchers can have reasonable confidence that adolescents' current recollections about their experiences of maternal acceptance-rejection are likely to be in moderate agreement with what they would have reported had they been tested during childhood.

Resumen

In the case of assembly wellhead, a spacer spools was used to provide space and connect between parts of the wellhead. In order to design spacer spool with specified material should comply the standards and procedures of the oil and gas industry. The results of the material calculation were using the ASME BPVC guidelines. These three materials strengths were calculated if used as a body spacer spool. Based on acceptance criteria on API 6A 21st Edition, these three materials were categorized as acceptable to be used as a body spacer spool for this specification. These three materials strengths were also calculated the stress of the flange and flange rigidity criteria. Based on the acceptance criteria on ASME BPVC guidelines, the results showed that these materials can be used for flange because it had stress value under yield strength of material which was flange rigidity criteria for operating condition has 0.59 and 0.66 for testing condition because had value of rigidity that met with minimum acceptance criteria.

Resumen

Virgin plastic pellets are widely used as raw materials in flexible plastic packaging which generate abundant postconsumer plastic waste. The widespread use of recycled plastic pellets as raw materials will reduce plastic waste generation significantly. However, substitution of virgin materials need high quality of recycled plastic pellets which produced from good quality of plastic waste. Design for material value conservation in this case study was a trial implementation of design principles of plastic bag in order to minimize its value degradation of plastic waste, and therefore increase its acceptance by plastic recycling industries. A Structural Equation Modelling (SEM) with Lisrel 8.8 software used as tool of analysis in evaluating consumer acceptance of the two types of design paradigm, current design and material value conservation based design. The results indicated that consumers accepted both type of packaging. With final standard factor loading, the proposed design indicated slightly better correlation coefficients: 0.46 for Ease of Information Delivery and 0.74 for Informational Content variables, better than current design with 0.44 and 0.73 coefficients. Widespread implementation of design for material value conservation will save virgin plastic consumption for plastic packaging production, reduce plastic waste generation as well as support material resource conservation in a better condition of environment. The social and economic benefit will also be obtained as multiplier effect of material value conservation.

Resumen

In space applications, day by day, the electronic devices are becoming compact with increase in operating frequencies and high power requirements posing challenges in design and selection of materials for high thermal dissipation requirements. In order to achieve optimum performance from thermal management material, engineers have to focus on high reliable, cost effective alternatives. Such materials need to demonstrate excellent thermal conduction to minimize thermo-mechanical stress and fatigue due to operations like soldering, thermal cycling and severe operating conditions. The paper describes a new family of thermal management composite material called “SILVAR”.

Resumen

Flexible plastic packaging which rejected or with low acceptance as raw materials for secondary recycling need relevant evidence and explanation of its cause, and then, need a systemic solution on how to increase the acceptance level. Coloring and printing on flexible plastic packaging were predicted as the significant source of impurity that reduces the value of plastic material at the end of packaging life cycle. Otherwise, optimum use of label or sticker as printing media for informational and promotional purpose on the packaging proposed as a key solution in material value conservation. The existing practices which focused on how to manage abundant plastic waste generation, replaced by a new paradigm which focused on how avoid waste generation by conserving the material value systematically. This research revealed that flexible plastic packaging materials with no color pigment and no printing ink were suitable for secondary recycling to produce high quality of recycled plastic pellets and leverage the selling price. Therefore, labelling on the surface of packaging that protect purity of the material can be considered as one of methods in the implementation of material value conservation on flexible plastic packaging. Another benefits of the implementation of material value conservation are to improve the utilization of virgin plastic and its recycled plastic pellets as raw materials with better quality.

Resumen

This study explored the relation between perceived maternal acceptance and control, and acting-out aggressive behavior in children diagnosed with ADHD. 81 dyads of mothers and children participated. Children ranged in age from 8 through 13 years ( M = 10.8 yr., SD=1.7). 63 children were boys, 18 were girls. Mothers ranged in age from 28 through 55 years ( M = 41.1 yr., SD = 5.58). 78% were posthigh school or college graduates. Both mothers and children responded to self-report questionnaires assessing children's behavior as well as mothers' behavior toward their children. Analysis showed that mothers were consistently accepting, and they tended to be firm in behavioral control. Children were reported by mothers as displaying only moderate acting-out aggressive behavior. Multiple regression analyses showed that both maternal acceptance and maternal control made significant and independent contributions to variations in children's acting-out behavior. Approximately 22% of the variance in scores on acting-out aggression was explained by a linear combination of maternal acceptance and behavioral control. None of these relations varied significantly by age or sex of the child.

Resumen

Insulation elements are distinguished in inorganic fibrous and organic foamed materials. Foamed insulation materials are of great acceptance and use, but their major disadvantage is their flammability. In case of fire, they tend to transmit the flame producing toxic gases. In this paper, the synthesis and characterization of innovative inorganic insulation materials with properties competitive to commercial is presented. Their synthesis involves the mixing of inorganic raw material and water with reinforcing agent or/and foaming agent leading to the formation of a gel. Depending on raw materials nature, the insulation material is produced by freeze drying or ambient drying techniques of the gel. The raw material used are chemically benign and abundantly available materials, or industrial by-products and the final products are non-toxic and, in some cases, non-flammable. Their density and thermal conductivity was measured and found 0.02-0.06 g/cm3 and 0.03-0.04 W/mK, respectively.

Resumen

The results of a comprehensive study of the crystal and electronic structures, kinetic and energetic performances of the semiconductor thermometric material Er1-xScxNiSb, (x=0–0.1) are presented. Microprobe analysis of the concentration of atoms on the surface of Er1-xScxNiSb samples established their correspondence to the initial compositions of the charge, and the diffractograms of the samples are indexed in the structural type of MgAgAs. Because the atomic radius Sc (rSc=0.164 nm) is smaller than that of Er (rEr=0.176 nm), it is logical to reduce the values of the unit cell's period a(x) Er1-xScxNiSb, which correlate with the results of mathematical modeling. The temperature dependences of the resistivity ln(ρ(1/T)) contain high- and low-temperature activation regions, which are specific for semiconductors and indicate the location of the Fermi level in the bandgap, and positive values of the thermopower coefficient a(x, T) specify its position – near the valence band . This result does not agree with the results of modeling the electronic structure for its ordered version. The presence of a low-temperature activation region on the ln(ρ(1/T)) p-ErNiSb dependence with an activation energy =0.4 meV indicates the compensation of the sample provided by acceptors and donors of unknown origin. A decrease in the values of the resistivity ρ(x, T) and the thermopower coefficient a(x, T) points to an increase in the concentration of holes in p-Er1- xScxNiSb in the area of concentrations x=0–0.03. This is possible in a p-type semiconductor only by increasing the concentration of the main current carriers, which are holes. The fact of increasing the concentration of acceptors in Er1-xScxNiSb at insignificant concentrations of impurity atoms is also indicated by the nature of the change in the values of the activation energy of holes from the Fermi level to the valence band . Consequently, if in p-ErNiSb the Fermi level was at a distance of 45.4 meV from the level of the valence band , then at the concentration Er1-xScxNiSb, x=0.01, the Fermi level shifted towards the valence band and was located at a distance of 13.6. Since the Fermi level reflects the ratio of ionized acceptors and donors in the semiconductor, its movement by x=0.01 to the valence band is possible either with an increase in the number of acceptors or a rapid decrease in the concentration of ionized donors. At even higher concentrations of Sc impurity in p-Er1-xScxNiSb, x≥0.03, low-temperature activation sites appear on the ln(ρ(1/T)) dependences, which is a sign of compensation and evidence of the simultaneous generation of acceptor and donor structural defects in the crystal nature. This is also indicated by the change in the position of the Fermi level in the bandgap of the semiconductor Er1-xScxNiSb, which is almost linearly removed from the level of the valence band : (x=0.05)=58.6 meV and (x=0.10)=88.1 meV. Such a movement of the Fermi level during doping of a p-type semiconductor is possible only if donors of unknown origin are generated. For a p-type semiconductor, this is possible only if the concentration of the main current carriers, which are free holes, is reduced, and donors are generated that compensate for the acceptor states. This conclusion is also confirmed by the behavior of the thermopower coefficient a(x, T) at concentrations x≥0.03. The results of structural, kinetic, and energy studies of the thermometric material Er1-xScxNiSb allow us to speak about a complex mechanism of simultaneous generation of structural defects of acceptor and donor nature. However, the obtained array of experimental information does not allow us to unambiguously prove the existence of a mechanism for generating donors and acceptors. The research article offers a solution to this problem. Having the experimental results of the drift rate of the Fermi level as the activation energy (x) from the Fermi level to the valence band by calculating the distribution of the density of electronic states (DOS) sought the degree of compensation, which sets the direction and velocity of the Fermi level as close as possible to the experimental results. DOS calculations are performed for all variants of the location of atoms in the nodes of the unit cell, and the degree of occupancy of all positions by their own and/or foreign atoms. It turned out that for ErNiSb the most acceptable option is one that assumes the presence of vacancies in positions 4a and 4c of the Er and Ni atoms, respectively. Moreover, the number of vacancies in the position Er (4a) is twice less than the number of vacancies in the position Ni (4c). This proportion is maintained for Er1-xScxNiSb. Vacancies in the positions of Er (4a) and Ni (4c) atoms Er1-xScxNiSb are structural defects of acceptor nature, which generate two acceptor zones and in the semiconductor. The introduction of impurity Sc atoms into the ErNiSb structure by substituting Er atoms in position 4a is also accompanied by the occupation of vacancies by Sc atoms and a reduction in their number. Occupying a vacancy, the Sc atom participates in the formation of the valence band and the conduction band of the semiconductor Er1-xScxNiSb, acting as a source of free electrons. We can also assume that the introduction of Sc atoms into the structure of the compound ErNiSb is accompanied by a process of ordering the structure of Er1-xScxNiSb and Ni atoms occupy vacancies in position 4c. This process also, however, 2 times slower, leads to a decrease in the concentration of structural defects of acceptor nature. In this case, Ni, giving valence electrons, now act as donors.

Resumen

Cirkulär ekonomi bygger på principerna om att designa bort avfall, där avfall ses som en råvaruresurs. För att övergå till ett fossilfritt samhälle kommer material från förnyelsebara råvaror att behövas. Biobaserade material har oftast inte samma tekniska egenskaper och estetiska uttryck som befintliga material, biobaserade DIY-material utvecklade från okonventionell råvaruresurs kan väcka starka positiva och negativa reaktioner hos användarna. Studien har undersökt hur man i en Material driven designprocess genom form och kultur kan skapa acceptans för ett biobaserat DIY material från en okonventionell råvaruresurs. Studiens huvudsyfte har varit att bidra med ny kunskap för att underlätta för designers i en Material Driven Designprocess, att identifiera användningsområden och produktform som kan stärka materialacceptans hos användare. Fördjupningsområden i studien är teorier för Hållbar utveckling, Cirkulär ekonomi, Bioekonomi, Material Driven Design for Sustainability och Culture Sensitive Design. Huvudmetoden i studien har varit Material Driven design, vilket innefattas av ett flertal designmetoder. Studien visar på att den kulturella koppling mellan användarna och råvarans ursprung har i denna studie haft en signifikant betydelse för material acceptansen genom att skapa mening för användaren och att materialet primärt behöver applicerat i en produkt på ett sådant sätt att användaren känner tillit till dess prestanda. Resultatet presenteras i form av ett förslag på en användare studie och en produktprototyp.
A circular economy is based on the principles of designing away waste, where waste is seen as a raw material resource. To move to a fossil-free society, materials from renewable raw materials will be needed. Bio-based materials usually do not have the same technical characteristics and aesthetic expressions as existing materials, bio-based DIY materials developed from unconventional raw material resources can provoke strong positive and negative reactions among users. This study has investigated how a Material-driven design process through form and culture can create acceptance for a bio-based DIY material from an unconventional raw material resource. The study's main purpose has been to contribute with new knowledge to make it easier for designers in a Material Driven Design process to identify uses and product forms that can strengthen material acceptance among users. In-depth areas in the study are theories for Sustainable Development, Circular Economy, Bioeconomy, Material Driven Design for Sustainability and Culture Sensitive Design. The main method of the study has been Material Driven Design, which is covered by several design methods. The study shows that the cultural link between the users and the origin of the raw material has had a significant impact on material acceptance by creating meaning for the user and that the material primarily needs to be applied in a product in such a way that the user has confidence in its performance. The results are presented in the form of a proposal for a user study and a product concept.

Resumen

The present study examined the relations among maternal psychological control, maternal acceptance, maternal acculturation and youth anxiety within the framework of a (partially) moderated mediation model. The sample consisted of 535 Hispanic-Latino youth (46% girls; M = 9.79 years) and their mothers. The study’s data were analyzed using structural equation modeling in the MPlus statistical software program. Results indicated that maternal psychological control and youth anxiety are significantly and positively related. Results also indicated that more acculturated mothers were more psychologically controlling than less acculturated mothers. Results further provided evidence for a partial mediational role of maternal psychological control on the relation between maternal acculturation and youth anxiety symptoms. In addition, there was a direct, positive relation between maternal acculturation and youth anxiety symptoms. No significant findings were observed regarding the moderating role of maternal acceptance on the relation between maternal psychological control and youth anxiety. The findings’ theoretical and clinical implications are further discussed.

Resumen

The mineral industry is currently challenged by low metal prices and depletion of high grade resources with increasing depth combined with complex geology. Achieving profits in-spite of these difficulties has been challenging and the standard industry response to tackle the situation is by pursuing economy of scale. Only large scale companies can adopt this method due to the high capital investment involved. The alternate solution is to recognize and introduce low cost mining and mineral processing methods. The current research aims at increasing profitability of a mining operation by efficiently utilizing the mineral resource and increase the recovery. The research focuses on exploiting inherent heterogeneity in an orebody with the development of a sophisticated tool that can perform real time, with online analysis and decision support systems to designate the destination of the material being mined. The research includes measuring and modeling a deposit’s heterogeneity at both BHP Billiton’s Spence and Escondida mines. This is followed by the development of two digital models to evaluate the opportunity to adopt selective partitioning of ore, prior to hauling the mined material to the mill. An apparent increase in profitability is observed due to increased ore recovery. Determining and exploiting this heterogeneity offers different insights in orebody grade distribution, evaluating resources and reserves and production planning, all leading to more complete utilization of the resource.

Resumen

The current study examined the role of self-reported and child-reported maternal lack of acceptance in increasing the likelihood of developing internalizing and externalizing symptoms among children with ADHD symptomatology. The effects of a social desirability bias on mother’s self-reports of rejection were controlled for. Mother-child agreement about parenting behaviors like warmth/affection, hostility/aggression and indifference/neglect was also investigated. In addition, variables with the potential to affect agreement (i.e., parents’ social desirability bias, child age, child sex) were examined. Participants included 120 boys and 90 girls, 6 to 11 years old (M = 8.25, SD = 1.18) with and without ADHD and their primary parent/guardian (N = 209). Parent and child participants completed self-report instruments separately. Results indicate that the relationship between mother-and-child-reported ADHD symptoms and internalizing symptoms is strongest when mothers exhibit low levels of rejection. Among the ADHD subsample, maternal lack of acceptance acts as a risk factor by strengthening the relationship between hyperactive/impulsive symptoms and externalizing symptoms. In addition, mothers and their children report significantly different levels of parenting behaviors. Child age and child sex were significant predictors of parent-child disagreement.

Resumen

This thesis is based on a research project aimed at creating new electron acceptors from cyclopenta-fused polycyclic hydrocarbons (CP-PAHs). We have utilized Pd-catalyzed cyclopentenelation reactions to create 2,7-bis(trimethylsilyl)cyclopenta[hi]aceanthrylene 1 and 2,7-dibromocyclopenta[hi]aceanthrylene 3. Upon bromination these fullerene fragments serve as a building block for creating both small-molecule and polymeric electron acceptors. The resulting materials are dark green and possess narrow band gaps with low-lying lowest occupied molecular orbitals (LUMO). A fluorescence quenching at poly(3-heylthiophene) demonstrates the electron accepting behaviors of the materials. Traditional semiconductors are integrated with an CP-PAH core creating small molecules (or small molecules are created consisting of a CP-PAH core, complementary semiconductor, and aromatic substituents).

Resumen

The urgent need to find alternative sources of energy has been recognized as a major challenge of the 21st century. Many ideas have been proposed, but harvesting the energy of the Sun has been identified by many as the most promising alternative to satisfy the world’s increasing energy demand. Among the current technologies to harness solar energy, photovoltaics and artificial photosynthesis (photocatalysis) stand out. Although very different in their strategies, both technologies entail a core principle, the generation of a charge-separated state. To this end, both methods employ electron acceptors that will receive the photo-electron; in most cases this role is played by C60 or its derivatives. Our research group has synthesized and characterized an octanuclear iron-oxo cluster with remarkable electrochemical properties which compares favorably with the reduction potentials of C60 and derivatives. This dissertation explores the use of this octanuclear cluster as electron acceptor for solar energy applications. To assess the viability of Fe8 as an electron acceptor in photocatalysis, electron donors that could coordinate to its iron atoms via phenol groups were synthesized and characterized. These electron donors were used in efforts to make molecular dyads, but coordination was not achieved. The altenative strategy studied was the preparation of Fe8-based hybrid materials that can be casted with known polymer electron donors. Several hybrid materials were prepared and their general properties investigated. These materials exhibited the desired electrochemical traits as well as the general castable behavior of the polymer host. These hybrids are now ready to be tested in polymer solar cells.

Resumen

Abstract This chapter uses a feminist material-discursive theoretical framework to examine how women adopt the subject position of ‘monstrous feminine’ via the role of premenstrual embodiment. In this examination, Ussher and Perz draw on interviews they conducted with women who self-diagnose as ‘PMS sufferers.’ They theorize that this self-positioning is subjectification, wherein women take up cultural discourse regarding idealized femininity and the stigmatized fat body; according to the authors, this results in distress, self-objectification, and self-condemnation. However, they argue that women can reduce premenstrual distress and resist negative cultural constructions of premenstrual embodiment and fat bodies through women-centered psychological therapy, which increases awareness of embodied change and leads to greater self-care and acceptance of the premenstrual body.

Resumen

This study presents the material challenges associated with Advanced Reactor Concepts (ARC) such as the Advanced High Temperature Reactor (AHTR). ARCs are the next generation concepts focusing on power production and providing thermal energy for industrial applications. The efficient transfer of energy for industrial applications depends on the ability to incorporate cost-effective heat exchangers between the nuclear heat transport system and industrial process heat transport system. The heat exchanger required for AHTR is subjected to a unique set of conditions that introduce several design challenges not encountered in standard heat exchangers. The corrosive molten salts, especially at higher temperatures, require materials throughout the system to avoid corrosion, and adverse high-temperature effects, such as creep. Given the very high steam generator pressure of the supercritical steam cycle, it is anticipated that water tube and molten salt shell steam generators heat exchanger will be used. In this paper, the American Society of Mechanical Engineers (ASME) Section III and Section VIII requirements (acceptance criteria) are discussed. Also, the ASME material acceptance criteria (ASME Section II, Part D) for high temperature environments are presented. Finally, lack of ASME acceptance criteria for thermal design and analysis are discussed with potential benefit.

Resumen

The results of comparative studies of the dependence of the operational properties of surfaces with functional layers and coatings deposited on them on their technological compatibility with the main material of the parts are presented. Investigations were carried out on parts with a copper-modified surface layer, a nickel-phosphorus coating, and multicomponent functional layers based on a polymer. It has been established that the same coating or functional layer on different materials shows different values of the coefficient of friction and the different nature of its change from the time of contact interaction with the counterbody, as well as different indicators of endurance and corrosion-fatigue strength, which is explained by their technological compatibility with the main material of the part, depending on the method of preliminary surface treatment.

Texto completo

Resumen

According to the current ASME Code Section XI, IWB-3640 and Appendix C flaw evaluation procedure, cast austenitic stainless steel (CASS) piping with ferrite content less than 20% is treated as wrought stainless steel. For CASS piping with ferrite content equal or greater than 20%, there is currently no flaw evaluation procedure in the ASME Code. In this paper, the technical basis for a proposed flaw acceptance criteria for CASS piping is presented. The procedure utilizes the current rules in ASME Code Section XI, IWB 3640/Appendix C and the existing elastic-plastic correction factors (i.e., Z-factors) for other materials in the Code. The appropriate Z-factor to use for the CASS piping is determined based on the ferrite content (using Hull’s equivalent factor). Experimentally measured fully saturated fracture toughness and tensile data of the three most common grades of CASS material in the US (CF3, CF8 and CF8M) were used to determine the flaw acceptance criteria in the proposed method. The proposed method is conservative since it utilizes the fully saturated condition of CASS materials. In addition, it is simple and consistent with current regulatory guidance on aging management of CASS piping.

Resumen

In order to avoid a pollution of the near surface ground water during the post closure phase of the Konrad repository the acceptable amount of material harmful to water in the radioactive waste is restricted. For this purpose the KONRAD plan approval order includes waste requirements referring to the German water law (“water law permission”). In a first part of this contribution the water law permission for the KONRAD repository is introduced. This permission contains a list of materials harmful to water with the respective limitations in mass and many instructions and proposals regarding the registering and balancing of these materials as well as quality assurance aspects. The second part deals with the implementation of the water law permission in the waste acceptance criteria. The waste producer has to describe his waste in a standardized way with respect to the material composition. The operator of the repository has to check this description and to register and balance the materials and substances harmful to water. This procedure is based on a standardized list of materials and a list of containers. In the third part quality control measures used for the proof of the compliance with the acceptance criteria (with respect to the water law permission) are described. In particular objective of the quality control, possible quality control options and acceptable margins are dealt with.

Resumen

ASME Code Case 2235 and the new adoption of this Code Case into ASME Code Section VIII, Div. 2 has acceptance criteria which were based on predicted flaws and fracture mechanics modeled after the nuclear industry. These criteria were developed in response to a query about how to apply the acceptance criteria of ASME Article 4, Appendix 12 when using non-amplitude based ultrasonic methods such as phased array and time-of-flight diffraction. Since the traditional acceptance criteria were based on amplitude, they could not be applied for these alternative methods. The Code committees responded with a flaw size acceptance criteria based on the fracture mechanics properties of the materials and service conditions found in the nuclear industry. This was a major improvement and added a technical basis for the criteria lacking in past standards, however, there are no limitations or qualifications in CC 2235 on its applicability to other materials or service conditions. This is a concern for some oil refining and other plant services, especially those leading to embrittlement, various types of hydrogen-induced damage or high cycle fatigue cracking. The CC 2235 criteria were also not adequate for the recent major industry problem with reheat cracking in 2 1/4 Cr-1 Mo-V reactor fabrication. This paper summarizes the basis for CC 2235, describes the concerns with applying the acceptance criteria without consideration of material or service conditions, and suggests how to approach the issue from a better informed perspective and in some cases, establish stricter maximum flaw sizes.

Resumen

The Indiana Department of Transportation (INDOT) Central Hot Mix Asphalt (HMA) Acceptance Lab was opened on March 29, 2018 at the Office of Materials Management (OMM) facility in Indianapolis. The state-of-the-art lab conducts acceptance testing on HMA samples from INDOT’s Crawfordsville and Greenfield districts, as well as testing of appeals samples from the other four INDOT districts. Each HMA sample undergoes multiple sequences acceptance testing processes. In 2019, project SPR-4353 “Central HMA Acceptance Lab Process Improvement Project” was conducted with the goal to improve organization, flow of work and efficiency in the central region HMA Acceptance Lab for all tests done, and provide implementation leading to the reduction of turnaround time from six days to four days. This project follows key recommended actions from SPR-4353 to implementation.

Resumen

For decades, researchers have sought to understand the adhesion of ice to surfaces so that low-cost ice mitigation strategies can be developed. Presently, the field of ice adhesion is still without formal standards for performing ice adhesion tests. The U.S. Army Corps Engineers’ Research and Development Center’s Cold Regions Research and Engineering Laboratory (ERDC-CRREL) has a longstanding history as an independent third party for ice adhesion testing services. Most notably, CRREL’s Zero-Degree Cone Test (ZDCT) has been an industry favorite for more than 30 years. Despite its wide acceptance, the ZDCT contains some shortcomings, namely that freshwater ice is formed on the surface of interest within the confines of an annular gap. To address this limitation, CRREL developed and uses the Ice Adhesion Peel Test (IAPT) for testing ice adhesion. This test employs an open planar substrate from which the ice can be removed under either tensile or shear loading, thereby allowing ice to be grown directly on the target substrate without the use of molds. The IAPT configuration is therefore amenable to different ice types and geometries and will provide utility to research studies that aim to develop surface treatments to mitigate ice in a wide range of environments. This report describes the IAPT and its use for characterizing the ice adhesion properties of materials.

Resumen

The main objectives of this project were to review the available balanced-mix design (BMD) methodologies, understand the I-FIT and Hamburg Wheel Tracking Test (HWTT) test methods using INDOT asphalt mixtures, and to explore the application of these tests to both a BMD approach and as performance-related Quality Control (QC) and Quality Acceptance (QA) methods. Two QA mixture specimen types, plant-mixed laboratory-compacted (PMLC) and plant-mixed field-compacted (PMFC) were used in the determination of cracking and rutting parameters. Distribution functions for the flexibility index (FI) values and rutting parameters were determined for various mixture types. The effects of specimen geometry and air voids contents on the calculated Flexibility Index (FI) and rutting parameters were investigated. The fatigue characteristics of selected asphalt mixtures were determined using the S-VECD test according to different FI levels for different conditions. A typical full-depth pavement section was implemented in FlexPAVE to explore the cracking characteristics of INDOT asphalt mixtures by investigating the relationship between the FI values of QA samples with the FlexPAVE pavement performance predictions. The FI values obtained from PMFC specimens were consistently higher than their corresponding PMLC specimens. This study also found that FI values were affected significantly by variations in specimen thickness and air voids contents, having higher FI values with higher air voids contents and thinner specimens. These observations do not agree with the general material-performance expectations that better cracking resistance is achieved with lower air voids content and thicker layers. Additionally, PG 70-22 mixtures show the lowest mean FI values followed by the PG 76-22 and 64-22 mixtures. The same order was observed from the ΔTc (asphalt binder cracking index) of INDOT’s 2017 and 2018 projects. Finally, it was found that the HWTT showed reasonable sensitivity to the different characteristics (e.g., aggregate sizes, binder types, and air voids contents) of asphalt mixtures. Mixtures containing modified asphalt binders showed better rut resistance and higher Rutting Resistance Index (RRI) than those containing unmodified binders.
