“…Cao et al compared the internal temperature of asphalt and heat-reflective pavements; At 2.5 cm depth, the temperature of the traditional pavement reached 62.7 • C, while that of the heat-reflective one was reduced by 9 • C [12]. Outdoor tests and experiments on test sections have also been conducted to further confirm the cooling effect of heat-reflective coatings [7,10,20,21]. Furthermore, Jiang et al reported that heat-reflective pavements have better stability at high temperatures [17,22,23].…”

Heat-reflective coatings, used to reduce the asphalt pavement temperature and urban heat island effect, have a good cooling effect; coating development, however, generally focuses on cooling. This study aims to design a heat-reflective coating with both durability and cooling effect by considering the functions of each component, improving the coating bond strength and abrasion resistance, and conducting laboratory tests and test section verification. The coating developed exhibits bond strength and abrasion resistance 20% and 49%, respectively, higher than those of ordinary coatings. The experiments reveal a cooling effect of red coating up to 10.2 °C, a bond strength of up to 1.20 MPa at 25 °C, and an abrasion rate of up to 25% after 60 min; the cooling effect is basically the same as that for traditional heat-reflective coatings, but the bond strength and abrasion resistance significantly improved. In the analysis of the test section, the cooling effect reaches 7.0 °C, the performance of anti-skid decreases little, and the coating is still usable normally after 4 months.

“…The causes of urban heat island effect include the characteristics of urban ground surface, greenhouse gas emissions, concentration of heat sources, and air pollution. Roads are a major cause of urban heat island effect [67,68]. Pavement surface in the city, especially asphalt pavement, has changed the original thermal properties of the natural ground surface.…”

Extensive studies on traditional and novel engineering materials and the increasing 8 demands by growing traffic have led to tremendous changes of the function of roads. Roads, as an 9 important part of the human living environment, have evolved from structures that were designed and built for passing vehicles, to ecological assets with significant economic importance. In addition to structural stability and durability, functions such as noise reduction, urban heat island mitigation, de-icing and exhaust gas absorption, are also expected. This study focused on state-of-the-art research on the performance, applications and challenges of six environment-friendly functional road materials, namely the permeable asphalt concrete, noise-reducing pavement materials, low heat-absorbing pavement materials, exhaust gas-decomposing pavement materials, de-icing pavement materials, and energy harvesting pavement materials. With this study, we aim to provide references to the latest relevant literatures of the design and development of environment-friendly functional pavement, and promote innovation in materials science and pavement design principles. For this purpose, this review compiled extensive knowledge in modern road construction and related disciplines, in order to promote the development of modern pavement engineering technologies.

“…The technology of cool pavement is one of the ways to mitigate urban heat islands as it absorbs less heat and subsequently this will decrease the surface temperature [7]. Previous studies showed that many techniques in the making of cool pavement have been developed to reduce the surface heat temperature through mixture of variety of materials that consists of reflective material, vegetation cover, photovoltaic pavement, and waste tile [7,8,9,10]. However, this method is not adaptable to existing roads or pedestrian walkways because this will involve the construction of new pavement that can be costly and laborious.…”

Urban heat island (UHI) is a condition where urban area experiences increase in temperature than rural area caused by the affect from the modification of land surfaces. In urban areas, roads are one of the main elements that contribute to UHI as roads are mostly paved with dark pavement. When pavements become hotter, the excess heat is radiated back into the atmosphere resulting in a higher surrounding temperature than those in rural areas. The objective of this study is to develop a new coating material for pavers from VG2S that can reduce surface heat. Two methods were used in this study, immersed and layered methods for comparing standard paver with new innovated paver with VG2S coating. FLIR thermal imaging camera and infrared thermometer gun are used for measuring surface heat. The surface heat result shows reduction in surface temperature by 5°C to 10°C compared to uncoated standard sample and white paint color pave sample (control) which are slightly lower by 1°C to 2°C from coating sample. The studies demonstrated that VG2S coating can be applied as cool coatings and contribute to a significant reduction of the cooling demand in warm climates.
