摘要:
针对沥青路面铺筑的实际情况,通过综合热分析( DSC/TG)和红外光谱(FT - IR)实验方法,测试并分析了多种相变材料的储热能力及高温稳定性、高温耐久性,考虑了相态变化、相变温度、过冷度、相分离现象、高温性能等因素对沥青路面实际应用的影响,并对筛选出的聚乙二醇4000进行了沥青混合料试件成型过程中的温度模拟,结果表明聚乙二醇4000作为相变储热材料掺加进沥青混合料是可行的.
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.
