Ambient Temperature and Vehicle Loading Effects on Asphalt Concrete Pavement Rutting Development

In order to investigate ambient temperature and vehicle loading influence on asphalt pavement rutting development, ABAQUS is utilized to build pavement structure three-dimension model. Based on the actual temperature data, heat transfer theory, creep model and 3-D finite element method, the temperature filed variation law in pavement is calculated. And asphalt pavement rutting developments under different vehicle loadings in different ambient temperatures are analyzed. The results indicate that pavement rutting develops nonlinearly as ambient temperature varies; the rutting developing rate under high temperature condition is much higher than under low temperature condition; there is a linear correlation between rutting depth and vehicle loading under the same loading times; the rutting proportion developed in hottest season is much higher than any other seasons.
