The temperature field analysis model was established in different parts of transport vehicles during transport for asphalt mixture. And the reliability of the mathematical model built was verified by the temperature measurement in the construction site. Space time Distribution Characteristics of Temperature Field During Asphalt Pavement Paving was researched by the collection of temperature measurement in the construction site.The primary and secondary each factor were compared about cooling rate of warm mix asphalt by the method of gray correlation analysis. Based on the principle of non-state heat conduction in the thermal process of asphalt pavement, thermal diffusivity of asphalt mixture formula was derived. The required parameters thermal conductivity coefficient was obtained by the thermal conductivity tests. Based on this, the effect of different temperature and void on the thermal conductivity coefficient was analyzed. According to finite element method of the temperature field, the temperature field model in the process of warm mix asphalt compaction was built. And the influence factors on cooling rate of warm asphalt mix in the the process of compaction of asphalt pavement was analyzed.
