Abstract
The structure stress of concrete pavement with asphalt overlay with traffic loads,temperature stress is analyzed by finite element method.The result is compared with the one of the structure with the treatment of anti-crack.The influence of traffic loads,temperature changes,and the material parameters on the structure stress of asphalt overlay is studied.The results show that STRATA stress absorbing interlayer is set on the old cement concrete pavement and the load transfer efficiency at joints is improved simultaneously,the stress and strain in the asphalt overlay structure under traffic and temperature loads can be improved significantly.
