| Abstract: | Based on the theory of heat transfer,the two dimensional finite element of asphalt pavement for temperature field analysis is modeled by applying the software of ANSYS.The paper computes pavement temperature field by analyzing the heat steady,then analyses the heat transient state.The results indicate that the temperature of asphalt pavement will reduces large scale in the cases of the temperature decreases suddenly. |
