“…These properties are detailed in Table A1 , demonstrating their necessary roles in various applications. Also, as shown in Table A1 , the most frequently employed materials as PCM are polyethylene glycols, or PEGs, notably PEG2000 and PEG4000, due to their significant enthalpies during phase changes [ 12 , 13 , 25 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ]. These materials exhibit desirable attributes such as thermal and chemical stability, non-toxicity, and an appropriate phase change temperature range [ 44 ] during the phase change from solid.…”

“…Conversely, PCM with higher melting points around 50 °C to 60 °C, such as types PEG1000 to PEG8000 [ 12 , 13 , 25 , 26 , 35 , 36 , 37 , 40 , 42 , 62 ], OP55E [ 63 ], stearic acid (SA) [ 11 , 64 ], PCM-43 and PCM-48 [ 46 ], and ceresin wax [ 65 ], could be employed in high-temperature thermal energy storage applications. These are particularly suitable for tropical and temperate locales where summer temperatures can get excessively high, posing a risk to the mechanical integrity of asphalt material.…”

“…This makes them useful in specific high-temperature applications, such as industrial processes operating at elevated temperatures to store excess heat. PEG4000, with an average melting point of 56.14 °C, provides enhanced thermal stability over PEG2000, with a slightly lower average melting point of 50.63 °C [ 12 , 13 , 25 , 35 , 36 , 37 , 38 , 39 , 40 , 41 , 42 , 43 ]. These insights into melting points and their application in cooling asphalt reflect the fundamental role of PCM in mitigating the UHI effect.…”

“…In this sense, it is vital to carry out detailed studies, and the mechanical properties of pavements incorporating PCM must be deeply considered. For this purpose, wheel tracking and dynamic creep tests are most suitable for examining asphalt pavement’s permanent deformation [ 24 , 25 , 26 ].…”

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.

Phase change materials (PCMs) have been incorporated into asphalt concrete pavements because they can regulate the temperature by absorbing and releasing heat during physical state changes. This effect reduces temperature gradients of pavements and, consequently, increases its service life. This work presents a systematic review of recent articles published in peer-reviewed journals (available in the Scopus database) involving asphalt mixtures with PCMs and focusing on mechanical characterization. It is observed that most of the selected papers investigated the benefits of polyethylene glycol as a PCM. The most common strategy to avoid leakage during the phase transition involved using a porous material that acts as a carrier matrix for the PCMs. Generally, asphalt pavements with PCMs are systems with favourable thermal transferability, thus demonstrating higher heat absorption and dissipation rates. Finally, the asphalt mixtures containing PCMs showed lower mechanical performance than the control mixtures. However, they still satisfy the required criteria. In any case, it is expected that with the incorporation of PCMs into asphalt pavements, the social and environmental effects (Urban Heat Island) of sunlight in urban areas can be mitigated by the thermoregulation phenomena.
