Full textThis research is devoted to the analysis of means used to define stabilization/solidification processes of specific industrial wastes. The selected wastes are a used catalyst containing vanadium V(V) and an activated charcoal polluted by iodine. We have shown that the water absorption capability, which is linked to the waste porosity, is the key factor of a treatment; the choice of the adequate binder for this treatment is suggested by the behavior of the bulk waste during leaching. Two treatment processes, one based on hydraulic binder stabilization and the other based on bitumen stabilization, are developed and tested. In both cases, it appears that the physical and chemical properties of the binder and the mixing of the waste and the binder determine the efficiency of the treatment. Thus we observed that the effectiveness of the hydraulic binder to chemically stabilize the bulk waste is linked to the waste solubility level in the binder leachates. Regarding bitumen, it appears that the treatment efficiency mainly depends on bitumen viscosity. The waste/hydraulic binder mixing process is based on a selected order of constituents’ incorporation and on selected proportions ratio. The waste/bitumen mixing process proved to depend on two parameters: the workability temperature and the residence time at this temperature We propose an empirical model that allows to evaluate the latter. After treatment of the two wastes using both processes, it appeared that although vanadium is reduced in V(IV) by bitumen, it is not more stable. By incorporating vanadium in its hydrates, the hydraulic binder chemically stabilizes the waste. It is therefore more efficient to treat the catalyst. Iodine is not chemically stabilized by these binders. However, by ensuring a greatest physical retention, the bitumen-based process constitutes the best approach for charcoal treatment. This methodology, based on the link between waste and binder, provides acceptable results on the viewpoint of the stabilization/solidification by two different binders. It opens interesting perspectives considering the number of existing hydraulic binders and bitumen

Full textThis study deals with the mechanical and rheological behaviors of neat and polymer-modified bitumens. The viscoelastic properties of several pure bitumens are studied as a function of the temperature and the frequency. The results show that the time temperature superimposition principle (TTSP) is not available for asphaltenic and/or waxy bitumens. Moreover, the modification of the bitumen by polyethylene or styrene-b-butadiene copolymers leads to a heterogeneous material. For the polymer contents below 6%, the dispersed phase is a polymer-rich phase. The viscoelastic properties of the binder at high temperature are improved due to the polymer addition. On the other band, the bitumen matrix controls the stiffness of the binder at low temperature. The study of the fracture properties at - 20°C show neat and polymer-modified bitumens are brittle materials. Nevertheless, the polymer addition contributes to improve the binder toughness

Full textAt present, considering crude oils diversity and different formulations, there is a great variety of road bitumens, with chemical compounds or not (polymers,. . . ). So, physico-chemical methods of modified bitumens must set of macroscopic approaches and microscopic approaches too, ideal to characterize in situ differents components. Nevertheless, one of industrial difficulties of bitumens manufacturing is to choose quickly a crude oil or mixture of crude oils leading to the final characteristics wished for bitumens. In order to answer to this industrial matter, a new macroscopic approach of bitumens spectroscopic study, based upon statistical treatment, have been developped to create bitumens maps. These ones present a great benefit industrial as an decisional help. Explanatory patterns by multiple regression or partial least squares have enabled to identify links between chemical and physical parameters. So, inspite of the judicious choice of crude oils, bitumens, during their road service life, asphalts harden due to weathering (temperature, UV,. . . ). Consequently, their mechanical properties are modified. Then, in order to limit theses phenomenons, a polymer can be added. Polymer Modified Bitumens (PMB) are composite materials with a highly complex structure. Understanding how this microstructure is affected by any changes in PMB composition is a very important objective. So, for this purpose, FTIR microscopy and UV Fluorescence microscopy were used in order to characterize in situ differents components. FTIR microscopy displayed promising results to make a mapping of the specimen with respect to local polymer concentration. Most PMB display a biphasic structure with polymer rich areas along with polymer poor regions. The size and the composition of those areas are bitumen dependent. They also dramatically change through the cross linking process. The chemical species that swell the polymer involve certain types of aliphatics and slighty condensed aromatics. In any case, the polymer dispersion is greatly enhanced by the cross linking process

Full textThe aim of this thesis is to study the potential of a natural bitumen (NB) mined in Albania in the production of hard bitumens (HB) and that of high modulus asphalt concrete (HMAC). Various petroleum refining techniques are available for the production of HB. Nevertheless, this is impossible with some crude oils. In addition, HB from refineries often present shortcomings which limit their applications. These reasons, coupled with practical issues related to HB supply, motivate the research of alternative methods. In this industrial context it is interesting to use NB. This study has shown that the Albanian NB provides HB and HMAC in accordance with European Standards, resistant to aging and relatively performant at low temperatures. The proper dosage of this NB allows the formulation of materials of desired properties, in response to the technical requirements of the considered road applications, facilitating in this way the use of bitumen stocks in asphalt concrete production plants

Full textModern concerns lead us to maintain and expand our communication routes while preserving natural resources. In this context, the use of hydraulic road binders (HRB) during excavation works allows the use of in place materials having initially poor geotechnical properties. This thesis work deals with the valorization of a wastepaper sludge ash (WSA), industrial by-product from recycled paper, and a natural pozzolan as key components of new HRB. Physical, chemical and mineralogical characterization of these materials was carried out. Their reactivity with lime and gypsum was evaluated using a new chemical test method developed to assist the HRB design. If this method remains to be optimized, it allows the design of HRB using pozzolan or WSA without clinker. Finally, the performance of HRB, formulated by the developed chemical test method or with a part of CEM I, were characterized on mortars and treatment of two clay soils. An environmental assessment of a binder containing a majority of WSA finishes the study

Full textIn this work, the feasibility of a valorisation in road engineering of non-hazardous waste incineration bottom ash aggregates (NHWI) is investigated. This study is first based on an experimental determination of the elastic properties of the bottom ash particles. These properties serve as input data for hierarchical multi-scale modelling developed to study the mechanical behaviour of aggregates treated with binders (cement and bitumen). The original experimental campaign on the bottom ash particles allowed them to be mapped to the Scanning Electron Microscope (SEM). For the particles, a mean reduced modulus of elasticity in between 15 and 68 GPa was found by means of indentation tests and applying the "Olivier and Phan method. The chemical analysis of the aggregates was obtained using qualitative point chemical analyzes (OHS). Based on a 0/25 particle size distribution of NHWI, which was the subject of an experimental study [BEC 07] , we have implemented two 30 models < road materials treated with binders in Representative Elementary Volumes (REV). These models are based on a hierarchical multi-scale modelling strategy. Two types of binder are studied: cement CEM I 42.5 R and bitumen of [NGU 08]. For both types of binder, the treated aggregates we divided into two REV, at respectively the sub-mesoscale (0/6 mm) and the mesoscale (6/25 mm). An application to the valorisation of NHWI bottom ashes in road engineering is studied in both cases. With a 3% cement treatment, a numerical simulation campaign "Virtual Laboratory" was conducted. At the sub-mesoscale, the input parameters for the Concrete Damaged Plasticity Model used at the mesoscale are determined. At the mesoscale, the mechanical characteristics of the road materials usually determined through experiments have been found. The developed simulation strategy has been validated by comparing our numerical results and son experimental results of [BEC 07]. With a 5% bitumen treatment, stress relaxation tests carried out at the two scales enable one to obtain the thermo-rheological properties of the Bitumen Bound Gravel. These properties are the Prony series at a reference temperature of 0°C and the Williams-Landei- Ferry (WLF) law constants. Prony series are obtained by means of standardized elastic moduli. The obtained WLF law constants are Cl = 20 °C-1 and C2 = 130 °C. The numeric simulations have been validated by comparing the responses of heterogeneous and corresponding homogeneous materials

Full textAprès une étude bibliographique sur la rhéologie et les propriétés thermo-mécaniques des bitumes, des mastics et des enrobés bitumineux, le travail expérimental mené aussi bien dans le domaine des petites déformations que des grandes déformations, est exposé.
Le comportement à basse température des bitumes a été évalué avec trois tests fondamentaux largement répandus : i)l'essai de module complexe, ii)l'essai de fluage au BBR, iii)l'essai de traction directe SHRP à vitesse de déformation constante et températures constantes. En outre, un nouvel essai de fissuration, consistant en un essai de flexion trois points sur éprouvettes de bitume préentaillées, a été développé à l'ENTPE. Les paramètres de ténacité et d'énergie de rupture des bitumes à basses températures ont pu être déterminés en utilisant les hypothèses de la MLR (Mécanique Linéaire de la Rupture).
Le comportement thermo-mécanique des enrobés bitumineux à basse température a été étudié en réalisant i)des essais de module complexe, ii)des mesures du coefficient de dilatation-contraction thermique, iii)des essais de traction à vitesses de déformation constantes, iv)ainsi que des essais de retrait thermique empêché.
Tout d'abord, des liens pertinents entre les propriétés des liants et des enrobés, et des caractéristiques suffisamment discriminantes au regard des propriétés à basse température des enrobés ont été mis en évidence. Ensuite, l'analyse a consisté à effectuer un travail de modélisation du comportement des liants et des enrobés, en petites et grandes déformations.
Un modèle rhéologique monodimensionnel, qui consiste en une généralisation du modèle analogique de Huet-Sayegh, a été développé dans le domaine des petites déformations. Ce modèle, appelé modèle “2S2P1D”, permet de simuler correctement à la fois le comportement visco-élastique linéaire des bitumes et celui des enrobés bitumineux. A partir de ce modèle, une transformation originale –indépendante du modèle– permettant de prédire le module complexe de l'enrobé à partir de celui du liant est proposée, puis validée.
Enfin, la dernière partie de cette thèse est consacrée à la loi généralisée monodimensionnelle “DBN” (Di Benedetto-Neifar) à partir de laquelle un programme a été développé sur l'interface Visual Basic du logiciel Excel. Ce programme constitue un outil simple de prévision du comportement de l'enrobé bitumineux sous diverses sollicitations (mécaniques et/ou thermiques). Ce modèle rhéologique permet de faire le lien entre les petites et les grandes déformations. Des simulations d'essais de traction à vitesses de déformation constantes, ainsi que des simulations d'essais de retrait thermique, monotones ou cycliques, sont enfin présentées.

Full textThis thesis deals with the thermomechanical behavior of bituminous materials at low temperatures. The binder behavior was evaluated with three fundamental tests : i)the complex modulus determination, ii)the Bending Beam Rheometer and iii)the tensile strength at a constant strain rate and constant temperatures. A three point bending test on pre-notched bitumen beams was also developed. The thermo-mechanical mix behavior was studied by performing i)complex modulus tests, ii)measurements of the coefficient of thermal contraction, iii)tensile tests at constant temperatures and strain rates, and iv)Thermal Stress Restrained Specimen Tests. Apart from the determination of some pertinent links between binder and mix properties and discriminating characteristics with regard to the thermal cracking of bituminous mixes at low temperatures, the analysis has also consisted in modeling the behavior of bituminous binders and mixes, both in the small strain domain and in the large strain domain

Full textAsphalt is a petroleum-based product used mostly as a binder in road pavement. Because the worldwide petroleum production appears to have come to a stand still, it might become difficult to answer the need in asphalt. That’s why the search for new materials has become of highest importance. This thesis deals with a new biomass : microalgae, and the focus has been made on the microalgae Scenedesmus sp. . From this specie, 22% of a lipid fraction can be extracted. This fraction, made of free fatty acids and aliphatic biopolymer, shows some interesting viscoelastic behavior, similar to the one of petroleum bitumen. Switching this extracting process to hydrothermal liquefaction, which occurs in aqueous media, almost 50% of the biomass can be turned into a bio-oil. Rheological properties of those bio-oils seem to be correlated to the experimental conditions, even though no proof has been provided yet

Full textAn experimental programme has been performed on three types of bituminous mixes with variable recycling rates and the possible addition of rejuvenator. The mix composition and the production process have been defined in order to perform a comparative analysis. The coating process modifies the physico-chemical parameters of the binders, like consistency, glassy transition temperature, cristallizable moiety, aromatics and asphaltenes rates; the above variations are limited by using the rejuvenator. As the RAP content increases, the compactibility and the rutting of the mixes decrease and the viscoelastic stiffness increases, but the rejuvenation reduces these variations. Globally, RAP increases the fatigue resistance of the mixes and flattens the Wöhler curve. Rejuvenation enhances ɛ6 fatigue parameter; fatigue performances increase with R&B temperature and colloidal index of the binder and as the viscous component of the mixes decreases. The positive impact of a high rate of RAP and of the rejuvenation on the allowable traffic has been evaluated from the structural design of a threelayered pavement. At low temperature, the deterioration of the tension ductility and of the stress restrained failure temperature produced by the RAP, is limited by the rejuvenation; a compromise with the fatigue resistance has to be found. The rejuvenated mixes laid as surface layers on a provincial road have experienced a smaller evolution that non rejuvenated mixes
