摘要
将相变材料与沥青混合料结合可有效地调节路面温度,预防或减轻沥青路面病害,并缓解城市热岛效应。总结了相变储能材料掺入沥青混合料的方式及相应的调温效果,指出不同掺入方式的缺点并提出了相应的解决措施;为提高当前主流的掺入方式-复合定形的调温效果,提出了理论有效储能效率指标作为优选复合定形相变材料的载体;同时,展望了相变储能沥青混合料的发展趋势,以期为沥青路面用相变材料的研究和应用提供参考。
The application of phase change materials in asphalt mixture can effectively adjust the temperature of asphalt mixture and prevent asphalt pavement diseases.The methods of the phase change energy storage materials mixed to the asphalt mixture and the corresponding temperature regulation effect were summarized.The disadvantages of each mixed method and the corresponding solution measures were expounded emphatically,In order to improve the temperature-regulating effect of the composite shaping,the theoretical effective energy storage efficiency was proposed to select the composite shape phase change material carrier,And the development trend of phase change energy storage asphalt mixture was pointed out,so as to provide reference for the research and application of phase change material in asphalt pavement.
