摘要
相变材料(PCMs)由于其独特的储能特性,已广泛应用于工业、建筑等领域,是一种可以用于道路工程领域中的新型材料,具有良好的应用前景。在总结近几年国内外相关研究的基础上,对相变储能材料在调温沥青路面方面的应用研究进行了概述。介绍了共晶系相变材料与定形相变材料的基本概念,进行了基于相变材料的路表温度模型调温机理分析,重点阐述相变材料掺入沥青混合料的方式,对该研究领域的一些现存问题进行了探讨。并提出了适用于沥青路面的相变材料的性能要求与标准,展望了相变调温沥青路面的发展趋势和应用前景。
Phase change materials （PCMs） has been widely used in industry, construction and other fields due to its unique energy storage performance, and has a good application prospect in road engineering. This paper summarized the application research development of phase change materials in temperature-adjusting asphalt pavements based on domestic and international references. The basic concepts of eutectic PCMs and form-stable PCMs were introduced, the temperature- adjusting mechanism of pavements surface temperature model based on PCMs was analyzed, the methods of asphalt mix- tures mixing with PCMs were expounded emphatically, and some existing problems in this research fields were discussed. Then the performance requirements and standards of PCMs suitable for asphalt pavements field were proposed, also the future research direction and the prospective were pointed out.
