摘要
根据国外的模量与温度的关系模型,分析了沥青路面在不同温度及模量下的力学状态。结果表明:随着温度的降低、模量的升高,在行车荷载的作用下沥青路面结构中的中性轴上移,最大拉应力逐渐增大,易导致路面出现裂缝。
According to relation model of modulus and temperature, analyze the mechanics appearance of asphalt pavement with different modulus and temperature. The results show with the going up of modulus and lower temperature, the meutral axis of asphalt pavement moves up and the maximum tension stress increses under the action of vehicle load and leading to crack.
