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 temperatureadjusting asphalt pavements based on domestic and international references. The basic concepts of eutectic PCMs and formstable PCMs were introduced, the temperatureadjusting mechanism of pavements surface temperature model based on PCMs was analyzed, the methods of asphalt mixtures 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 was proposed, also the future research direction and the prospective were pointed out．
