Experimental results showed that low heat accumulation asphalt mixture had a marked effect on the reduction of surface temperatures. However changes in temperature over the test methods were not thoroughly studied. In the process of test, LJ infrared powder is used to prepare for making the content of 6% asphalt mixture specimen. Several temperature data of infrared powder specimen were compared with the data of ordinary specimen. Each number was compared and analyzed. At last, concrete temperature variation discipline of the temperature field was found.
