Numerical and Experimental Validation of Full-Depth Asphalt Slab Using Capturing Solar Energy

It becomes a popular current to design different types of functional asphalt concrete in order to solve the city "heat-islands effect". Especially, the conductive asphalt mixture adding the graphite powders, would improve the non-deformable in high temperature and resist the cracking in low temperature. A full-depth asphalt slab is designed using the capturing the solar energy. In the study, the numerical simulation and experimental research are combined in order to validate the vertical temperature distribution of the full-depth asphalt slab. The results show that the numerical model can be used to predict the vertical temperature distribution of asphalt pavement and decrease the experimental cost and energy, at the same time, which has validated the testing result. All those can provide pavement engineers with a computational guide.
