Asphalt is a sticky plastic material,its modulus and strength will change with temperature and the actual bearing capacity of pavement structure will change as well. A new method was used to evaluate the temperature change of asphalt pavement. By simulate solar radiation on asphalt sample to study the change of the temperature field. The temperature distribution of the asphalt concrete under the same light radiation and circulating water was also studied. The results indicate that this method can be a good simulation of solar collectors on the surface temperature field.展开更多
