An outdoors experiment was launched for the development of an evaporative cooling pavement system and simulation model in the previous paper (Part 1). In this paper (Part 2), the characteristics of heat and water balance on this evaporative cooling pavement were investigated with a focus on surface wet condition and water content of the pavement. This analysis was conducted using empirical data of sunny and cloudy daytime conditions throughout a year. The results from this study showed the following: (1) Surface wet condition has a large impact on the evaporation and surface temperature of the pavement. (2) There is a correlation between water content and surface wet condition. (3) There is a correlation between water content and vertical water content distribution. These results indicate that surface wet condition depends on water content of the pavement during daytime. This finding is significant and meaningful for the modeling of heat and water balance on evaporative cooling pavement systems.
