Abstract
Temperature profile in asphalt pavement manifests nonlinear distribution which varies with time. In the past researches, there exist two major approaches; one uses a correlation between air temperature and temperature measured in pavement, and the other considers the effect of solar radiation. However, asphalt which has a strong characteristics of absorbing and storing heat, also emit the heat to the atmosphere. Dust and waterdrop in the atmosphere also radiate heat to pavement This paper presents a general thermal flow model between pavement and its surroundings and the effect of factors involved in the model on the temperature distribution in pavement using meteorological data
