Analysis of Thermal Stress for Asphalt Surface on Porous Concrete Base

Abstract:

In the paper, three–dimension finite element model of asphalt pavement, which includes transverse contraction joint of porous concrete base and asphalt surface, is established for the purpose of studying thermal stress of asphalt surface which is located in transverse contraction joint of porous concrete base. Calculation results of thermal stress are compared with each other. The results show that thermal stress of asphalt surface increases with increase of surface’s modulus, and thermal stress of asphalt surface increases with increase of ratio of base’s modulus to foundation’s modulus, and thermal stress of asphalt surface increases with increase of temperature field of base.
