To alleviate the urban heat island effect during summer and reduce pavement damage,the concept of “cool pavements” has been implemented.Among them,phase change materials (PCMs) have been favored by road engineering researchers due to their self-regulating temperature properties.This paper introduced the classification and characteristics of PCMs,outlined the models of heat transfer mechanisms of pavement,and discussed the influencing factors.Addressing the issue of performance degradation in direct incorporation of PCM modified asphalt,the paper proposed the use of composite PCM materials and elaborated on their application effects.Additionally,the paper summarized the advantages and disadvantages of testing methods for evaluating the temperature control effects of PCM modified asphalt,and provided an overview of the cooling effects and performance influences of composite PCM materials on asphalt and asphalt mixtures.Finally,it highlighted the research directions of current PCM materials for pavement,and presented improvement methods and prospects for addressing the issue of PCM leakage.
