“…The particle sizes of PCM, an aspect key to leakage risk (pointed out in Table A2 ) and thermal performance, have been studied extensively. The PCM in Table A1 exhibit a wide range, from a minuscule 0.0002 mm [ 45 ] to a larger 9.5 mm [ 37 , 46 ], with an average particle size of 1.27 mm. In the case of common materials such as PEG2000 and PEG4000, the average particle sizes are 0.4 and 0.6 mm, respectively.…”

“…For instance, SiO 2 encapsulation is frequently used with popular PCM like PEG2000 and PEG4000 [ 25 , 38 , 41 , 42 ]. Additionally, there are less commonly used strategies, such as adsorption on diatomite silica microporous structures [ 62 , 64 ], the use of PCM in composite form [ 38 , 58 ], polymerisation [ 31 , 77 , 78 ], emulsion polymerisation [ 52 ], and integration with multi-walled carbon nanotubes (MWCNT) [ 45 ], along with more advanced techniques like microencapsulation [ 79 ] and shape-stabilised expanded graphite [ 26 , 80 ]. Carrier matrix materials can also influence the thermal properties of PCM under various conditions (as shown in Table A1 ).…”

“… TiO 2 -containing combinations outperformed those with Al 2 O 3 in terms of thermal and mechanical characteristics due to TiO 2 ’s superior properties, leading to improved ageing properties of the asphalt binder. [ 45 ] Commercial materials called PCM-43 and PCM-48, the constituents of which were not specified. The maximum temperature difference between the sample with 9% PCM-43 (PCM-48) and the control was about 6 °C (4 °C) after 3 h of heating.…”

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.
