1. Introduction
In the urban area, the heat island phenomenon and hot nights when the temperature does not fall below 25 C outdoors are becoming environmental problems. Pavements cover a high percentage of the urban area and largely affect the development of the urban heat island phenomenon. There are many reports on cooling pavements to improve the thermal conditions in the urban environment and to reduce the energy consumption (Santamouris, 2013; Kinouchi et al., 2004; Synnefa et al., 2011; Hendel et al., 2014). As countermeasures in the field of road engineering, water retaining pavements and solar radiation reflective pavements with the surface temperature rise reducing function (STRRF) have been developed. Especially, a water retaining pavement consists of open graded asphalt pavement (porous asphalt pavement: PoAs) and a cement-based material grouted into voids in the PoAs. In general, the cement-based grouting material (CBGM) has a high water absorption of, for example, 40–80% by mass, and the water retaining pavements reduce the surface temperature by 10 C and more, as compared with a conventional asphalt pavement, which reaches over 60 C in the hot summer climate.Kinouchi et al. (2004) have developed an asphalt pavement with high albedo (reflection coefficient) and low brightness using an innovative paint coating. Their field measurements show that the maximum surface temperature of the paint-coated asphalt pavement is lower than that of the conventional asphalt pavement. Synnefa et al. (2011) have developed colored thin lay asphalt pavements with higher solar reflectance. The results of their field measurements show that an off-white asphalt sample having the highest solar reflectance has the greatest difference from the conventional asphalt sample.
