Abstract

On the basis of Wuhan district weather conditions of January 5, 2010, heat transfer mechanism of Beijing-Zhuhai Expressway Hubei section of asphalt concrete pavement based on snow melting is analyzed and the model of heat transmission is established. The average temperature of tube fluid is calculated for a given heat flux based on the analysis of the heat transfer of pipes. Heat flux of different meteorological conditions is investigated and the results show that the rate of snow fall and outdoor temperature are the key factors, the wind velocity is the main factor and the air relative humidity is the minor factor.
