Abstract

In this paper, one traditional asphalt and three permeable pavements were constructed to evaluate the thermal characteristics of pavement temperature at different depths and heat output in the field. The data were collected from May to July, 2011 to analyze with six traditional Chinese summer solar terms. On July 23, 2011 or Ta-Shu (great heat), it was the hottest day among six summer solar terms, while peak temperature of asphalt pavements was more than 60°C and ambient temperature was 36°C occurring at 14:00. In addition, it was found that reflectivity was affected by the color of pavement materials, and the thermal conductivity was influenced by the structural characteristics of pavements. The average heat output of grass bricks was found the least in comparison with others. Some heat outputs of porous asphalt concrete were larger than that of dense-graded asphalt concrete, especially from 16:00 to 21:00, but mostly were lower after midnight.
