- Title:
- Selection of Phase Change Materials Used in Heat Storage Cooling Asphalt Pavement
- CLC:
- U414
- Abstract:
- According to the factual condition of asphal! pavement, the heat storage capacity, high temperaturestability and durability of common phase change materials used under normal temperatures are tested and ana.lyzed through Differential Seanning Calorimetry ( DSC) and Fourier Transform Infrared $pectroscopy ( F’T.IR ) , other factors such as phase stute transiion, phase change temperature, undercooling, phase separationand high temperature performance are considered as well, and then the proposed polyethylene glycol 4000( PEG4000 ) undergoes the temperature simulation of molding process of asphalt mixture specimen, the resultsshow that PEC4000 is feasible for adding into asphalt mixture as the phase change heat storage material.
