Temperature Stress Analysis of Concrete Overlay on Old Asphalt Pavement

Abstract:

Article Preview

Temperature is one of the most important factors affecting the design and performance of both flexible and rigid pavements. The functional as well as the structural performance of flexible and rigid pavements is highly dependent on the temperature regime to which these pavements are exposed. Temperature variations within pavement structure contribute to distress and possible failure of that structure. According to pavement temperature stress calculation principle, based on general finite element software ANSYS, the paper adopt three-dimensional finite element method analysed temperature stress in concrete overlay on old asphalt pavement,in which discussed influence law of overlay thickness and modulus, equivalent rebound modulus on base course top and overlay structure parameters to temperature stress, providing theoretical principle and basis for old asphalt concrete pavement overlay method base on reliability.
