Abstract
The field observation was continued to estimate the thermal radiation from asphalt pavement. The surface temperature, solar radiation, infrared radiation, temperature, humidity, wind velocity and precipitation were observed for a period of about 8 months including summer and winter. Surface temperature, solar radiation and infrared radiation measured were compared with that of calculated using multiple regression analysis equations, surface temperature and the radiations were estimated within 5°C and 50W/m2. The equations are able to estimate the total heat flux (=infrared radiation + reflected solar radiation + sensible heat transportation) from pavement surface and showed a good correlation with the measured.
