Abstract:
The rheology of asphaltic binders and their effects on asphalt concrete are discussed with the intention of improving the correlation between conventional mix design results and pavement performance. Test results show that mineral fillers increase the viscosity and pseudoplasticity of asphalts but do not always decrease the tan 8, except apparently at a lower frequency or at a higher temperature. Mineral fillers are also hard to mix homogeneously and quickly with asphalts. All these effects become more pronounced with a continuously increasing filler to asphalt (F/A) ratio, and uses are limited to a lower F/A range unless the processing temperature is adjusted properly. The abnormal drop in tan δ improves for some modified asphalts (e.g., air-blown or polymerized asphalt).

Abstract:
The use of recycled concrete aggregate (RCA) as a part of coarse aggregates in asphalt pavements confers economic and environmental benefits. Coarse RCA (CRCA) has inferior mechanical and physical properties compared to natural aggregates due to very porous and weakly adhered cement mortar. In this study, CRCA surfaces were coated with waste plastic bottles (WPB) and used at 15%, 30%, and 50% in the asphalt concrete. The Marshall, stiffness modulus, and dynamic creep tests were performed to determine the strength of hot mix asphalts against rutting. The results revealed that the use of untreated CRCA reduced the Marshall quotient and the rutting resistance of the asphalt concrete. The results of the stiffness modulus and dynamic creep tests indicated that CRCA incorporation increased permanent deformation in the tested specimens due to the reduction of asphalt concrete stiffness. However, the asphalt concrete containing treated CRCA had lower permanent deformation because WPB promotes CRCA stability by penetrating its void and reinforcing cement mortar. Furthermore, by raising the temperature, the strength of all asphalt concretes decreased against rutting, and the reduction rate was higher in the modified specimens.

Abstract:
Twelve portland cement concrete pavement (PCCP) test sections were constructed to compare with standard PCCP and asphaltic concrete pavement (ACP) to quantify the effects of the pavement surface texture on noise, safety, and winter maintenance. Asphalt pavements studied included a Strategic Highway Research Program asphalt, stone matrix asphalt (SMA), and Wisconsin standard asphalt. A dependency between the pavement textures and their noise characteristics was observed. Noise measurements indicated that uniformly transverse tined PCCP created dominant noise frequencies that were audible adjacent to the road and inside the test vehicles. Careful design and construction of transversely tined PCCP can reduce tire-road noise. No significant acoustical advantages of open-graded asphalts over the standard dense asphalt were found. The results of this research are preliminary and have not yet been approved by the Wisconsin Department of Transportation Council on Research.

Abstract:
The fracture toughness of asphalt concrete increases at low temperature and then decreases at temperatures below a certain level. Some polymers are known to have the property of improving the temperature susceptibility of asphalt binder at low temperatures. Therefore, this study evaluated the fracture toughness (KIC) of some polymer-modified asphalt concretes. Low-density polyethylene (LDPE), styrene–butadiene–styrene (SBS), and a mixed polymer of LDPE and SBS were used in this study. The fracture toughness KIC of normal asphalt concrete was compared with that of polymer-modified asphalt (PMA) concrete, and the effectiveness of polymer modification against falling values of KIC was evaluated at low temperatures. The results showed that PMA concretes, in general, showed better KIC than normal asphalt concretes, and the temperature at which the highest KIC was obtained was lower than that in the case of normal asphalt concrete. Therefore, the PMA concretes evaluated in this study had better fracture resistance than normal asphalt at low temperatures.Key words: asphalt concrete, polymer-modified asphalt, PMA, fracture toughness, differential thermal contraction, low-temperature damage.

Abstract:
Traditional methods for the structural design of pavement cannot be applied to the design of pavement on bridge decks. In this paper, a new method for the structural design of asphalt pavement on concrete bridge decks is presented. The method can be applied to pavement on girder, slab, and box-girder bridges and can be used whatever the considered degree of bonding between pavement and deck. The method consists of modelling the deck as a two-layer system and then calculating stresses and strains in the pavement–deck system by means of a multilayer system. The proposed methodology has been applied to study the behaviour of asphalt concretes, porous asphalts, and stone matrix asphalts on girder, slab, and box-girder bridges. There is a conclusion of this application that stands out for its practical character. The stone matrix asphalts have the best performance if fatigue is the main concern.Key words: bridge decks, asphalt pavement, design.

Abstract:
It is consensual that the self-healing property of asphalt concrete can repair the damage inside it during high temperature and rest period. In order to not affect the traffic, the rest period of asphalt pavement is very short and uncontrollable; so, it is necessary to obtain enough high temperature in a limited time to achieve higher healing efficiency of asphalt concrete. The purpose of this paper is to study the induction heating efficiency and healing behaviors of asphalt concretes doped with different conductive additives. Steel fiber, steel grit, and steel slag were added to asphalt mixtures as conductive additives to prepare induction healing asphalt concretes. The steel grit and steel slag were added to replace the aggregates of corresponding particle size by equal volume to ensure the consistency of asphalt concrete volume, which can avoid degrading the performance of asphalt concrete due to the change of porosity. The induction heating efficiency and healing rate of asphalt concrete were quantified by infrared camera and three-point bending-healing experiment, respectively. The results showed that the thermal properties of asphalt concrete changed with the addition of different conductive additives. The asphalt concrete with steel fiber had the best induction heating property. While steel slag had extremely weak induction heating speed, the better thermal insulation property of the asphalt concrete with steel slag resulted in a higher induction healing rate. It was suggested to add steel slag to induction healing asphalt concrete to improve the healing rate.

Abstract:
The effect of modification of asphalt concrete mixtures of different grain sizes with “Ric-Polycell” (Ukraine) and “Duroflex®-SMA” thermoplastic polymers (Germany), which were added directly to the asphalt mixer during their preparation, on the properties of asphalt concrete was studied. It is confirmed that it is more expedient to use stone mastic asphalt concretes with a larger size of mineral crushed stone grains on high-traffic roads, as they are more rutting-resistant compared to asphalt concretes with smaller size and content of crushed stone grains. The effect of the temperature of preparation and thermostating of asphalt concrete mixtures modified with the investigated thermoplastics on the compressive strength of asphalt concrete at a temperature of 50 °С, which were made of the studied mixtures, was investigated. It was found that the maximum possible temperatures of preparation and thermostating of asphalt concrete mixes provide a more complete modification. The effect of the content of thermoplastic polymers in the composition of asphalt concrete mixtures on the properties and rutting resistance of fine-grained asphalt concrete, as well as stone mastic asphalt concrete, was studied. It was found that adding the “Ric-Polycell” polymer in the amount of 1.5 % and 3 % by weight of bitumen in the composition of the studied asphalt mixtures in the asphalt mixer during their preparation increases the rutting resistance of asphalt concrete under the studied conditions by 2.52–3.86 times. Modification of asphalt concrete mixtures with the “Duroflex®-SMA” additive in the amount of 0.3 % and 0.6 % by weight of the aggregate by a similar technology also allows increasing the rutting resistance of the obtained asphalt concrete by 1.86–3.16 times. Using these modifiers in the future will have a positive effect on the service life of the entire pavement structure

Abstract:
Hot-mix asphalts exposed to hot weather and high traffic volumes can display rutting distress. A material that can be used to increase the stiffness of asphalt binders is gilsonite. On the other hand, from an environmental point of view, the virgin natural aggregates of asphalt mixtures can be replaced with recycled concrete aggregates. For these reasons, this study modified the asphalt binder with gilsonite by wet-process to improve rutting resistance, and replaced (by mass and volume) part of the coarse fraction of the aggregate with recycled concrete aggregate in two hot-mix asphalts with different gradations. Unlike other studies, a larger experimental phase was used here. Marshall, indirect tensile strength, resilient modulus, permanent deformation, fatigue resistance, and Cantabro tests were performed. An ANOVA test was carried out. If the replacement of the virgin aggregate by recycled concrete aggregates was made by volume, both materials (gilsonite and recycled concrete aggregate) could be used in hot-mix asphalts for thick-asphalt layers in high temperature climates and any level of traffic. The use of both materials in hot-mix asphalts is not recommended for thin-asphalt layers in low temperatures climates. It is not advisable to replace the aggregates by mass.

Abstract:
The main indicators of 29 types of asphalt and polymer asphalt concretes prepared with the use of neat bitumens of 2 grades and 7 types of polymer bitumens have been determined and comparatively analyzed in the work. The bitumens of grades BND 100/130 and BND 130/200 produced by the Pavlodar petrochemical plant have been selected for preparation of the asphalt concretes, polymer bitumens and polymer asphalt concretes. 7 types of the polymers (Elvaloy 4170, Elvaloy AM, Kraton D 1192A, Calprene 501, SBS L 30-01 A, KUMHO KTR, Butonal NS 198) have been selected for the modification of the bitumens. Short procedure has been represented for the preparation of the polymer bitumens. 29 types of the asphalt and the polymer asphalt concretes have been prepared with the use of the above bitumens and polymer bitumens (asphalt concrete of type A - 7, asphalt concrete of type B - 15, stone mastic asphalt concrete SMA-15 - 1, stone mastic asphalt concrete SMA-20 - 6). The following main indicators of quality have been determined for the asphalt concretes and polymer asphalt concretes by testing in relevant laboratory devices: 1) rut depth at the temperature of 60 °С after 10 000 passages of the wheel (ST RK EN 12697-22-2012); 2) tensile strength at the temperature of -30 °С (pr. EN 12697-46-2012); 3) compression strength at the temperature of 50 °С (ST RK 1218-2003); 4) water saturation (ST RK 1218-2003). It is found out that the modification of the bitumens with the polymers increases essentially the main standard indicators of the asphalt concretes: rutting resistance, strength at high temperatures and low temperatures, resistance to the cyclic freezing and thawing (frost resistance). The reactive polymers Elvaloy 4170 and Elvaloy AM are the most efficient among the used ones.

Abstract:
Milled asphalt removed from old pavement carpets requires tenable handling easily reachable through its incorporation within other paving materials. This work deals with the effects of such incorporation to dry compacted concretes. Fine, intermediate, coarse and whole portions of milled asphalts were blended to a reference concrete. Mechanical tests disclosed remarkable losses on its strengths and modulus of elasticity; for the stereoscope and scanning microscopy pointed out impaired transition zones between the cement paste and the milled aggregates involved by thin asphalt films. Nevertheless, the mechanical results shown that the concretes with incorporated milled asphalt aggregates are suitable for use in pavement layers as bases and sub-bases even with reduced mechanical parameters.

Full text
Abstract:
This thesis present novel non-destructive laboratory test methods to characterize asphalt concrete. The testing is based on frequency response measurements of specimens where resonance frequencies play a key role to derive material properties such as the complex modulus and complex Poisson’s ratio. These material properties are directly related to pavement quality and used in thickness design of pavements. Since conventional cyclic loading is expensive, time consuming and complicated to perform, there has been a growing interest to apply resonance and ultrasonic testing to estimate the material properties of asphalt concrete. Most of these applications have been based on analytical approximations which are limited to characterizing the complex modulus at one frequency per temperature. This is a significant limitation due to the strong frequency dependency of asphalt concrete. In this thesis, numerical methods are applied to develop a methodology based on modal testing of laboratory samples to characterize material properties over a wide frequency and temperature range (i.e. a master curve). The resonance frequency measurements are performed by exciting the specimens using an impact hammer and through a non-contact approach using a speaker. An accelerometer is used to measure the resulting vibration of the specimen. The material properties can be derived from these measurements since resonance frequencies of a solid are a function of the stiffness, mass, dimensions and boundary conditions. The methodology based on modal testing to characterize the material properties has been developed through the work presented in paper I and II, compared to conventional cyclic loading in paper III and IV and used to observe deviations from isotropic linear viscoelastic behavior in paper V. In paper VI, detailed measurements of resonance frequencies have been performed to study the possibility to detect damage and potential healing of asphalt concrete.  The resonance testing are performed at low strain levels (~10^-7) which gives a direct link to surface wave testing of pavements in the field. This enables non-destructive quality control of pavements, since the field measurements are performed at approximately the same frequency range and strain level.

Resumo: O principal objetivo deste trabalho é a determinação das principais propriedades do asfalto borracha e das propriedades mecânicas de um concreto asfáltico, tendo, como adição, o uso de borracha moída de pneus usados, tratada com solução de hidróxido de sódio comercial. Obtivemos, com o tratamento superficial da borracha de pneus usados, melhor interface entre a borracha e asfalto, assim como com o concreto asfáltico e a borracha, alcançando sensível aumento da durabilidade do asfalto-borracha. Realizamos, primeiramente, ensaios para caracterizar o asfalto-borracha tratado de acordo com as Normas vigentes, ensaios de durabilidade e, em seguida, ensaios mecânicos do concreto asfáltico. A recuperação elástica do asfalto-borracha utilizando pó de borracha tratada com hidróxido de sódio aumentou em 10% quando comparados com asfalto-borracha sem tratamento. Os resultados demonstraram melhora da estabilidade à estocagem em 42% nos ensaios realizados. Os ensaios de envelhecimento demonstraram que o tratamento do pó de borracha com hidróxido de sódio aumentou sensivelmente sua durabilidade. O ensaio de variação de massa, após o ensaio de envelhecimento, demonstrou que a perda de massa dos corpos de prova utilizando pó de borracha tratada com hidróxido de sódio foi 111% melhor quando comparados com os corpos de prova utilizando pó de borracha sem tratamento. Concluímos que há grande aplicabilidade deste asfalto-borracha na construção civil
Abstract: The main objective of this study is to determine the main properties of the asphalt-rubber and the mechanical properties of an asphalt concrete, with the addition of ground rubber from second-hand tires, treated with a sodium hydroxide commercial solution. We obtained, with the superficial treatment of rubber from second-hand tires, a better interface between the rubber and the asphalt, as well as with the asphalt concrete and the rubber, achieving significant increase in the durability of the asphalt-rubber. We undertake tests to characterize the treated asphalt-rubber according to current standards, durability tests, and then mechanical tests of the asphalt concrete. The elastic recovery of the rubber asphalt with rubber powder treated with sodium hydroxide increased by 10% compared to the untreated rubber asphalt. The results showed an improved stability to storage in 42% in the tests. The aging tests showed that the treatment of the rubber powder with sodium hydroxide significantly increased their durability. The mass change test after the aging test showed that the mass loss of the specimens with rubber powder treated with sodium hydroxide was 111% better when compared to the specimens with rubber powder without treatment. We conclude that there is great use of this rubber asphalt in the construction industry

Abstract:
Nondestructive laboratory seismic testing to characterize the complex modulus and Poisson’s ratio of asphalt concrete is presented in this thesis. These material properties are directly related to pavement quality and the dynamic Young’s modulus is used in thickness design of pavements. Existing standard laboratory methods to measure the complex modulus are expensive, time consuming, not truly nondestructive and cannot be directly linked to nondestructive field measurements. This link is important to enable future quality control and quality assurance of pavements based on the dynamic modulus.Therefore, there is a need for a more detailed and accurate laboratory test method that is faster, more economic and can increase the understanding and knowledge of the behavior of asphalt concrete. Furthermore, it should be able to be linked to nondestructive field measurements for improved quality control and quality assurance of pavements. Seismic testing can be performed by using ultrasonic measurements, where the speed of sound propagating through a material with known dimensions is measured. Seismic testing can also be used to measure the resonance frequencies of an object. Due to any excitation, a solid resonates when the frequency of the applied force matches the natural frequencies of the object. In this thesis, resonance frequency measurements have been performed at several different temperatures by applying a load impulse to a specimen while measuring its dynamic response. The measured resonance frequencies and the measured frequency response functions have been used to evaluate the complex modulus and Poisson’s ratio of asphalt concrete specimens. Master curves describing the complex modulus as a function of temperature and loading frequency have been determined through these measurements.The proposed seismic method includes measurements that are significantly faster, easier to perform, less expensive and more repeatable than the conventional test methods. However, the material properties are characterized at a higher frequency range compared to the standard laboratory methods, and for lower strain levels (~10-7) compared to the strain levels caused by the traffic in the pavement materials. Importantly, the laboratory seismic test method can be linked together with nondestructive field measurements of pavements due to that the material is subjected to approximately the same loading frequency and strain level in both the field and laboratory measurements. This allows for a future nondestructive quality control and quality assurance of new and old pavement constructions.

Abstract:
The article presents the results of dynamic modulus tests carried on the asphalt concrete (AC16W). The sinusoidal load was applied to the samples in accordance with DTC-CY method. The neat bituminous binder (penetration grade 35/50) was modified by means two synthetic waxes, coming from the Fischer-Tropsch raction, with various molecular weights and softening point temperature results (hard and softer). The relaxation phenomenon in terms of changes in complex modulus and phase angle was evaluated using the modified Huet-Sayegh (2S2P1D). Estimated model parameters pointed out that the addition of the synthetic wax with the high (hard wax) and the low (softer wax) molecular weight raised the stiffness of the bituminous binder in relation to the reference bitumen 35/50. The application of the modified Huet-Sayegh model showed that the presence of the synthetic wax in the bitumen significantly affected the stiffness modulus of considered asphalt concretes. Basing analysis on Cole-Cole diagram it was found significant differences in the viscoelastic behaviour between the reference asphalt concrete and the asphalt concretes with synthetic waxes. In contrast, there were no significant differences between viscoelastic properties of tested asphalt concretes modified, used in the experiment, synthetic waxes. Furthermore, the sensitivity to the loading time of asphalt concretes containing both synthetic waxes was marginal.

Abstract:
Asphalt concrete (AC) consists of asphalt binder and aggregate. Aggregate consists of: coarse aggregate and fines. Asphalt binder creates a coating or film around the aggregate, which is defined as the binder phase of AC. Fines are believed to be trapped inside an asphalt film or mixed with asphalt binder, creating a composite material called mastic. Thus, AC has three phases: mastic, asphalt film binder, and coarse aggregate. All these phases play major roles in performance of AC. Researchers have performed various tests on asphalt binder at micro scale to understand the macro scale behavior of AC. However, test methods developed and performed on binders, to this day, are mostly rheological shear and bending beam tests. No studies have been conducted on the compression stiffness or modulus and hardness of and binder, rather than shear and binders stiffness. In addition, the existing tests used in the asphalt area cannot be performed on binder and mastic while they are an integral part of AC. Nanoindentation tests can be performed on aggregate and asphalt binder while they are integral parts of AC. Because, in nanoindentation test, a nanometer size tip, which is smaller than binder film thickness as well as other phases. In the study, Performance Grade (PG) 64–28 was used for the study, same binder had been used afterwards to characterize asphalt and AC. A loading rate of 0.005 mN/sec, a dwell time of 200 sec and a maximum load 0.055 mN were employed in the study. In the current study 20 indentations were done on the asphalt binder sample and 100 indentations were done on AC sample, due to heterogeneity of the sample. However, to identify a specific phase in AC sample, the current study adopts the depth range technique for as same loading protocol. The depth rage of binder phase was acquired by independent indentation on same asphalt binder sample. As, asphalt is known to be a viscoelastic material that exhibits creep behavior, the creep compliance of asphalt binder was used for validation of the depth range assumption. The validation of phase identification was done by comparing the asphalt binder phase creep response while they are integral part of AC with creep response of independent asphalt binder sample under nanoindenter. The comparison shows depth resolution technique can successfully identify the binder phase of AC.

Abstract:
Asphalt concrete’s dynamic modulus (|E*|) is one of the key input parameters for structural design of flexible pavement according to the Mechanistic Empirical Pavement Design Guide (MEPDG). Till this day, pavement industry uses |E*| to predict pavement performance whether the material is hot mix asphalt (HMA) or warm mx asphalt or Reclaimed Asphalt Pavement (RAP) mixed HMA. However, it is necessary to investigate the correlation of |E*| with laboratory performance testing. In this study, laboratory dynamic modulus test was conducted on four different asphalt concrete mixtures collected from different construction sites in the state of New Mexico and mastercurves were obtained to evaluate dynamic modulus (|E*|) for a wide range of frequency. In addition, fatigue performance of these mixtures was predicted from the mastercurves and compared with the laboratory fatigue performance testing. Fatigue performance of these mixtures was evaluated from the four point beam fatigue test. The laboratory results show a good agreement with the predicted value from mastercurves. It is also observed from this study that the fatigue life of the asphalt concrete materials decreases with increase in |E*| value.

Abstract:
This report summarizes activities undertaken to support and ensure that the Illinois Department of Transportation utilizes the best demonstrated available technology for design and construction of full-depth hot-mix asphalt (HMA) pavements and HMA pavements on rubblized Portland cement concrete pavement (PCCP). To achieve this goal, the researchers reviewed pavement design and special provisions for full-depth asphalt and rubblization projects as well as full-depth asphalt and rubblization project performance via condition surveys and deflection measurements. They also modified design inputs as needed from the review of literature and responded to specific issues related to full-depth asphalt and rubblization design and construction. The researchers studied 32 rubblization projects on the interstate system and found this rehabilitation technique is providing good to excellent performance that exceeds design expectations. They provided input on proposed changes to full-depth hot-mix asphalt pavement on rubblized PCCP specifications as well as provided input on the RoadTec 1105e material transfer device. Analysis of traffic speed deflectometer data obtained on several hot-mix asphalt and rubblized pavements resulted in the development of analysis algorithms.
