Abstract: This paper describes stress and deformation analysis for different damage in flexible pavement at high and low temperature using hybrid visco-elastic FEM and relaxation test results in tension for bituminous mixtures, which were performed at different temperatures. Cracking due to thermal load and rutting are a big concern in flexible pavement. But, recently, many researchers had been reported that longitudinal cracking under wheel path at high temperature occurred. This cracking never occurred in surface pavement covered by overbridge in summer. We tried to analyze the cause of longitudinal cracking under wheel path at high temperature and thermal stress in flexible pavement at low temperature using hybrid visco-elastic FEM. This paper consists of experiment of relaxation modulus for bituminous mixtures taken from fields and stress analysis using hybrid visco-elastic FEM. Apparatus in order to measure relaxation modulus was modified in our laboratory. It was concluded that longitudinal cracking was caused by large shearing force due to radial tire of automobiles at high temperature and thermal stresses due to thermal load were almost the same for both rutting and longitudinal cracking sections in Swiss.
