摘要：

为了研究多层相变沥青混凝土复合结构的降温效果，采用差示扫描量热法测试了5组不同分子量聚乙二醇（PEG）的相变温度，结合太阳辐射下沥青路面温度场模拟结果，拟定并制备了含PEG的7组相变沥青混凝土三层复合结构，采用自行制作的热辐射及测温装置，测试了热辐射9 h内相变沥青混凝土复合结构内部温度，分析了PEG使用层位、层间组合方式、分子量对复合结构储热降温的影响。结果表明，PEG分子量从1000增大到6000时，相变起始温度从25.1 ℃增高到54.4 ℃；相变材料掺入路面结构单层后，主要对掺入层及其以下层位具有降温效果；从性价比角度看，仅上层掺入PEG的方案优于上中两层、上中下三层使用PEG的方案；在相同掺量时，分子量高的PEG对路面结构的降温效果优于分子量低的。

Abstract:

To investigate the cooling effect of multi-layer phase change asphalt concrete structure， the phase transition temperatures of five groups of polyethylene glycol （PEG） with different molecular weights were measured by differential scanning calorimetry. Seven groups of three-layer composite asphalt concrete slabs containing PEG were prepared based on the simulation results of asphalt pavement temperature field under solar radiation. The internal temperature of these composite asphalt concrete slabs within 9 h of thermal radiation was measured using the self-developed thermal radiation and temperature measurement device. And the effects of PEG addition layer， combination of PEG addition layer and molecular weight on the heat storage and cooling of composite asphalt concrete slabs were analyzed. Results show that the starting temperature of phase transition increases from 25.1 ℃ to 54.4 ℃ with the molecular weight of PEG increasing from 1000 to 6000. The cooling effect is mainly reflected in the mixing layer and its lower layers when phase change material was added to the single layer of pavement structure. The scheme of adding PEG in the upper layer is better than that of using PEG in multiple layers from cost performance. The cooling effect of PEG with high molecular weight is better than that of PEG with low molecular weight at the same content.
