Full textThe research work presented in this PhD thesis lies within the framework of a partnership between the laboratory Mechanics and Modeling of Materials and Structures in Civil Engineering (3MSCE, University of Limoges) and Eurovia, a subsidiary of the VINCI Group. The study aims at better understanding the mechanistic behavior of tack coats spread at the interface between two asphalt concrete (AC) layers. This behavior is characterized through a large experimental campaign. Then, the tests results are used in a finite element program. This program allows the pavement structure engineer to predict, on the one hand, the durability of the bonding at the interface, and on the other hand, the effect of modeling the interface behavior on the pavement response. In this research project, a laboratory double shear test device is designed and manufactured. By means of a mono-axis hydraulic press, the device allows applying a double shear loading at the interfaces of a symmetrical specimen which is consisted of three AC layers. Thus, monotonic, oligocyclic and fatigue tests are carried out at 10 and 20°C on an interface BBTM/BBSG (very thin AC layer overlaid on a dense AC layer). This interface is with or without tack coat (a cationic rapid-set emulsion with pure bitumen). The oligocyclic and fatigue tests were carried out in a force controlled mode, and lead to very innovative and interesting results. Three failure criteria are analyzed. The results clearly show that the lack of tack coat reduces the fatigue performance of the bonding (interface). Through the analysis of the results, a method is proposed, and allows predicting the fatigue law of the bonding from the monotonic shear tests results. This shear tests campaign is completed by a series of laboratory monotonic torque tests. Besides the characterization of the tack coats shear behavior, the experimental conditions where the torque and the double shear tests results are similar are specified. The last part of this work deals with, on the one hand, the effect of the interface shear behavior on the pavement structure design, and on the other hand, the effect of the repeated horizontal loads on the fatigue of the bonding at the interface. Two finite element models (2D and 3D) are developed in order to evaluate the mechanistic response of the pavement subjected to the French standard axle. Findings from this numerical simulation show that, when taking into account the horizontal loads, the fatigue of the bonding becomes predominant during the pavement structure design

Full textThe Soil-Mixing consists in mixing a hydraulic binder into the soil mechanically in order to improve its mechanical properties. Because of its economical as well as its sustainable advantages, this method so far confined to the improvement of compressible or high organic content soils has become an attractive alternative to traditional methods for soil reinforcement, retaining walls (temporary or final), foundations and cutoff walls. But these new applications imply new requirements on the method as well as on the material. Many studies on the subject provide some answers. However, there is no comprehensive parametric study examining both the impact of soil type and the amount of water on the characterization of the Soil-Mixing material and would improve the testing methods and methods for design of structures in Soil-Mixing.Soil-cement mixtures are predominantly composed of soil. The cement will represent at most 30% of the mixture. That is why we have chosen to follow a geotechnical approach rather than the concrete approach for this project.We followed an experimental program based on a laboratory study, realizing mixes called "reference" mixes. Three sand soil and five fine soils were treated by varying each time the quantities of cement and water to observe the influence of particle size, clay content and the amount of water present in the mixes on the resistance of the material, stiffness and failure strain. In addition, soils made from sand and fine soils were reconstituted and treated to study the impact of fines and their nature on the strength of the material.In parallel, monitoring of various projects has enabled us to study the implementation of the method, the homogeneity of the material produced in situ, and to compare the results with those of the parametric study. The results of this work are the creation of abaci connecting the resistance to the cement content and C/E ratio, and a summary table of experimental data of different mechanical properties of the Soil-Mixing material (depending on the nature of the soil), and formulas for granular soils predicting the strength after 7 and 28 days of curing depending on the percentage of fines in the soil and on cement content

Full textThe doctoral thesis analyses certain factors of influence that, through large temperature variations, frequently have a negative impact upon road pavements, especially the bituminous layers, with a view to determine the thermal-physical properties (thermal conductivity, specific heat, diffusive thermal, thermal effusion and emissivity) and to design and realize asphalt layers with better thermo-physical, and physical and mechanical characteristics.Practically, the studies highlighted in the thesis focus mostly on determining the thermal characteristics of asphalt mixtures, characteristics which help to combat the influence factors resulting from environmental conditions to which road structures are subject continuously road in the construction and repair stages, as well as during their service life. Due to being aware of temperature distribution in each bituminous layer of the road structure, the stresses occurring from variations of temperature can be controlled. The daily and seasonal fluctuations of air temperature, the intensity of solar radiation, the materials that make up the road structure layers by their geometry and surface conditions are some of the most important factors that significantly endanger the stability of the road structure.Positive contributions have been made on improving the thermal characteristics through designing and realizing asphalt mixtures in the composition of which, in addition to basic materials, flying ash was used as partial or total replacement for filler. This helps to obtain higher thermo-physical properties that have a favorable effect on physical and mechanical characteristics.Based on experimental results, some interesting and in the same time extremely valuable conclusions have been formulated opening a range of opportunities for further research in the field of road infrastructures

Full textTo ensure that road structures present a good mechanical strength, the layers that compose them are bonded together with tack coats. A new device, named 2T3C Hollow Cylinder Apparatus (2T3C HCA), has been designed in this thesis to characterise the thermomechanical behaviour of interfaces between pavement layers in bituminous mixtures. 3D Digital Image Correlation (3D DIC) has been used to find the displacement gaps at the interface. The behaviour of different interface configurations has been studied in the small strain domain, for which a new model was introduced to describe them, and in the large strain domain thanks to monotonic shear failure tests

Full textThe objective of the PhD thesis « Study and modelling of the pavement reinforcement with glass fibre grid under fatigue loading » is to characterize the reinforcement role of the asphalt surface layer of a pavement subjected to fatigue loading with the glass fibre grid or « geo-grid ». The fatigue behaviour of the composite formed of asphalt mixture and geo-grid is studied in laboratory with four point bending tests (4PB) performed with sinusoidal waveform, at 10°C and 25 Hz. The tested specimens are 630 x 100 x 100 mm3 beams of two types: asphalt beams (non-reinforced) and asphalt beams reinforced with geo-grid (reinforced). A four point bending prototype device was designed to perform the fatigue tests on the big size asphalt specimens. The device respects the European Standards. The experimental results were used for modelling of the damage evolution under fatigue loading of the both types of beams. The damage laws of the materials are Bodin laws programmed in Cast3M finite element code. Two categories of models were conceived, respectively: one layer beam models and tri-layers beam models. Each category has a model of non-reinforced beam and a model of reinforced beam. Furthermore, Castro-Sanchez model was used to predict damage evolution and in particular the number of cycles to failure correspondent to the two types of beams
