| Abstract: | By using the asphalt pavement structure that was built in indoor laboratory tank,a temperature field test and the detection of heat-reflective coating of a pavement structure were carried out.Combined with the obtained experiment data,the variation laws of road surface temperature,variable-temperature rate,temperature gradient,variable temperature amplitude and phases with depth for setting and not setting heat-reflective coatings were comparatively analyzed.Then,a finite element model was built and the mai... |
