Highway widening has become an effective way to improve the carrying capacity of existing expressways. However, assume that differential settlement between new and old subgrades is not controlled. In case, it will lead longitudinal cracks on pavement, which seriously affect safety vehicles. this study, variations elastic modulus dynamic under traffic load were studied by tests. A hyperbolic mod...

Asphalt is a kind of temperature-sensitive material. With the decrease temperature, deformation capacity an asphalt mixture will be significantly reduced. When temperature greatly reduced, layer produce large shrinkage tensile stress and strain, resulting in cracking. Therefore, cracking resistance behavior essential for asphalt. In order to study geosynthetics-reinforced under lower temperatur...
