Evaluation of Thermal Characteristics of Water-absorptive Pavements on Pedestrians

Abstract

Ministry of Land, Infrastructure and Transport in Japan suggested design guideline for buildings for reliving heat-island phenomenon in urban area, which indicated that decreasing surface temperature and easing thermal environment should be considered on plane and design for space of sidewalk. This report examines thermal characteristics of pavements. The pavements treated in this study are both water-absorptive pavement can be designed by using various colors and asphalt concrete. This study estimates the effect on pedestrians of different pavements through a numerical analysis based on the measured surface temperature of pavement and on actual meteorological data. It investigates thermal characteristics of pavements by applying a core-shell model of human temperature regulation and a rational temperature index.
