Firstly, based on the dynamic\r\nmodulus test of asphalt mixture, function relationship between the\r\ndynamic modulus of representative asphalt mixture and temperature\r\nwas obtained. In addition, the analytical solution for thermal stress in\r\nsingle layer was derived by using Laplace integral transformation and\r\nHankel integral transformation respectively by using thermal\r\nequations of equilibrium. The analytical solution of calculation model\r\nof thermal stress in asphalt pavement was derived by transfer matrix\r\nof thermal stress in multilayer elastic system. Finally, the variation of\r\nthermal stress in pavement structure was analyzed. The result shows\r\nthat there is obvious difference between the thermal stress based on\r\ndynamic modulus and the solution based on static modulus. So the\r\ndynamic change of parameter in asphalt mixture should be taken into\r\nconsideration when theoretical analysis is taken out.","references":null,"publisher":"World Academy of Science, Engineering and Technology","index":"Open Science Index 107, 2015"}
