General Situation of Studies on Non-Linear Temperature Field in Layered Pavement Structural System

The temperature field distribution in pavement structure reflects pavement structural roles acted by external environmental factors. And temperature stress caused by road temperature is one of the most important factors damaging pavements. So the studies on pavement temperature have theoretical guiding importance and high use value in engineering.The conditions of study on this problem are summarized in this paper,and existing prollems of studying process and calculating method are discussed too.
