Title: Thermal Stress Program of Asphalt Pavement Surface
Abstract: The linear relationship between the stiffness modulus and the temperature changes of the road was established according to the conventional mathematical formula of the stiffness modulus of asphalt and asphalt mixture.Based on the surface of the road surface temperature field,the surface temperature stress was solved by integral according to Hills cumulative thermal stress theory.Then,a current program for the temperature stress of asphalt mixture was worked out.This program can output the asphalt surface temperature stress directly after several conventional indicators of asphalt and asphalt mixture are input.The results adapt to the corresponding TSRST Test data by comparison.
