Analysis of Thermal Stress Response in Asphalt Overlay

The thermal stress response in asphalt overlay under different cooling conditions was analyzed considering thermal-viscoelasticity of asphalt mixture. The influence of cooling speed, initial temperature, cooling range, pavement thickness and base modulus on temperature stress were represented. The results indicate that, the cumulated thermal stress in asphalt overlay is small at high temperature; initial temperature and cooling speed distinctly affect thermal stress in asphalt overlay; reflective cracks occur in thinner asphalt overlay more easily, while top-down cracks happen in thicker asphalt overlay more easily; and too large base modulus is unsuitable to controlling thermal crack in asphalt overlay.
