Full textFlexible asphalt pavements are widely used in road construction. The design of these roads must take into account the behavior of the materials, traffic loading and weather conditions. In areas subjected to the freezing phenomenon, it is essential to take this phenomenon into account in pavement design, maintenance and rehabilitation. In fact, it can cause significant damages to roads, which appear as cracks or excessive deformations. The present work aims at analysis of the behavior of asphalt pavements subjected both freezing and traffic : The first chapter includes a literature review of researches conducted on the phenomenon of freezing effects in pavements. The second chapter is dedicated to the numerical modeling of the freezing phenomenon in soils treated as a tri-phasic porous medium. It presents the mathematical formulation of the coupled problem and its numerical solution using the finite difference method.The final chapter presents a finite element analysis of the pavement mechanical response to the phenomenon of freezing and traffic loading. This analysis is performed with a simplified approach that includes two steps: 1) it concerns solving the problem of freezing using a finite difference modeling. 2) it consists of the resolution, by the finite element method, of a mechanical problem considering the mechanical loads and the temperature effect

Full textTraffic induced Vibrations, especially by buses and heavy vehicles are a major concern in urban areas. The study of traffic vibrations is complex because it requires taking into account several aspects such as: vehicle modeling, the interaction between the vehicle and the road pavement and the wave propagation in free field or in a neighboring structure. The present work aims to study the vibrations induced by traffic in order to estimate their impact on the environment. The study was conducted by a three-dimensional numerical modeling in finite differences. The proposed model takes into account the mechanical characteristics of the vehicle, the interaction between the vehicle and the various types of road pavement and the vehicle speed. This model is validated by in situ measurements. In addition, we present measurements realized in cooperation with CETE North Picardy on an isolation method. The effectiveness of various isolation devices usually studied in the literature is analyzed. These devices include the trench barriers, the heavy surface blocks and the wave impeding blocks (WIBs)
