Abstract
Solar Radiation is a computable commodity, it is a function of a point on the earth's distance from the sun. For the past two years the Queensland Pavement Centre has been measuring Solar Radiation at a permanent monitoring station and comparing that with Road Surface temperatures every minute of every day. Some surprising results have been observed. It is postulated that Pavement Surface Temperatures increase by 5% for every Kilowatt per square metre of impact radiation, heat at twice the rate at which they cool during the hours of sunlight and emit heat beyond an equilibrium at the sun's zenith. Surface temperature will fall even though solar radiation is still impacting on the site. This data has been programmed into an asphalt calorimeter and temperature at depth in the pavement determined as a function of road surface temperature. These are all important factors when deciding on pavement design temperatures.
