This study investigates the heat transfer in asphalt collector. In this study, the first approach is based on increasing the heat gain which is captured by solar energy on asphalt pavement in order to decrease surface temperature. The second approach is related to decrease the time required to cooling the pavement surface. Experimental study used to determine the temperature distribution in the asphalt collector. The study was conducted with large scale of geometry; by using circulation water inside two separate layer copper coil in order to increase the contact area between the asphalt and fluid and compare the result with single layer different depth and combination between the upper and lower coil layer. The results of study show that the use combination of two layer coil have significantly on decreasing the surface temperature and enhance heat capture by bringing high amount of solar energy out which reduce the risk due to increase the temperature .
