摘要:
The thermal parameters are key parameters for evaluating the temperature field and temperature stress of asphalt pavement. However, due to the restriction of tradition test method, the thermal parameters of asphalt and asphalt mixtures measured by various researchers are quite different. Therefore, it is particularly important to introduce a simple and standard test method for thermal parameters of asphalt mixtures. This research proposed a novel test method to precisely determine the thermal parameters of asphalt mixture during compaction temp...
