“…Its unique thermal properties enable it to absorb and retain vast amounts of solar radiation. Consequently, the surface temperature of asphalt can skyrocket under direct sunlight, primarily due to its dark hue and low thermal conductivity [ 2 ]. As day transitions to night, this stored heat is progressively released, further amplifying urban temperatures [ 3 ].…”

This research presents a dual-pronged bibliometric and systematic review of the integration of phase change materials (PCMs) in asphalt pavements to counteract the urban heat island (UHI) effect. The bibliometric approach discerns the evolution of PCM-inclusion asphalt research, highlighting a marked rise in the number of publications between 2019 and 2022. Notably, Chang’an University in China has emerged as a leading contributor. The systematic review addresses key questions like optimal PCM types for UHI effect mitigation, strategies for PCM leakage prevention in asphalt, and effects on mechanical properties. The findings identify polyethylene glycols (PEGs), especially PEG2000 and PEG4000, as prevailing PCMs due to their wide phase-change temperature range and significant enthalpy during phase transitions. While including PCMs can modify asphalt’s mechanical attributes, such mixtures typically stay within performance norms. This review emphasises the potential of PCMs in urban heat management and the need for further research to achieve optimal thermal and mechanical balance.

“…Moreover, several other elements, like local climate, urban design, and construction density, intensify the UHI effect [ 3 ]. Recognising the severe implications of UHIs, which span from health hazards to heightened energy consumption and potential ecological ramifications, there is an urgent call for remedial measures [ 2 ].…”

“…

Asphalt pavement is the most widely used form of pavement in highways and urban road systems due to its advantages, and its application proportion is far greater than that of cement concrete pavement. However, asphalt pavement is black and its absorption rate of solar radiation can be as high as 85%-95% (Lei, 2010;Gong et al, 2020). Because of the strong temperature dependence, the persistently high temperature in summer leads to an increase in the temperature of the asphalt pavement, which is susceptible to rutting, shifting, oiling, and congestion (Si et al, 2018;Cheng et al, 2020).

High-temperature hazards of asphalt pavement and pollution from car exhaust are two major problems that need to be solved in road construction. In this paper, a multifunctional composite coating has been prepared from the perspective of reducing road temperature and car exhaust degradation. The principle of heat-reflecting coating is used to reduce the road surface temperature. At the same time, the TiO2 aqueous solution with photocatalytic degradation effect is added to the heat-reflective coating material to achieve the purpose of degrading automobile exhaust degradation, creating a new type of multifunctional coating that has both cooling and exhaust degradation effects. In addition, by changing the amount of carbon black, a multi-functional coating with the best coloring is selected, so that it has better functionality and has the most suitable shade for the road surface. Finally, the cooling effect and the exhaust gas reduction effect are examined through indoor and outdoor tests and the slip resistance of the coating is tested using the pendulum method. The results show that the functional coating group has a certain ability of cooling and exhaust gas degradation compared to the normal control group without coating. For the functional coating group with different carbon black content, the functional coating (G2) with 0.9% carbon black content has the strongest overall functionality. The cooling and exhaust gas reduction effects proved to be the best. The surface cooling rate is 5.4°C, while the internal cooling rate is 4.3°C. The cumulative degradation efficiency of CO and NO is found to be 27.77%, and 73.75%, respectively.
