| Abstract: | Taking thermalviscoelasticity theory as guide,using the method of test and finite element method,and simulating the viscoelastic property of asphalt mixtures with generalized Maxwell model,this paper launches out a profound study on the thermal stresses in pavements under the environmental conditions.Furthermore,the incremental thermalviscoelastic constitutive relation is obtained from theory derivation and the finite element model of thermalviscoelasticity is built.And a case is given. |
