Abstract
Temperature distributions in asphalt pavement with depth and time were measured every hour for a year continuously. As a result of statistical analysis, it was found that the difference of pavement structure does not affect surface temperature significantly, and that pavement temperature is related not only to changes in air temperature but also to other climate parameters, including changes in solar radiation, wind velocity and precipitation.
Temperature distribution in pavement was also estimated theoretically by a heat flow model proposed in which the heat transfer coefficient at the pavement surface and thermal diffusivity of the pavement materials were taken into account.
