基于有限元方法,建立了路面结构三维模型,计算了不同初始温度的沥青路面在不同降温速度下产生的温度应力,结果表明温度应力在80 mm深度内变化大,初始温度越高温度应力越大。

Based on the finite dement method, three-dimensional model of pavement structure is founded. The paper calculated asphalt pavement temperature stress in different initial temperature with the different cooling rates. The result shows that large change in temperature stress is within the depth of 80 mm, and the higher the initial tempera...
