Study on temperature field of asphalt pavement in tongliao, inner Mongolia

Abstract

In view of the special geographical landform, complex climate and serious influence of climate on roads in Inner Mongolia Autonomous Region, by studying the temperature field of asphalt pavement in Tongliao, Inner Mongolia, the respective characteristics and differences of the temperature distribution of asphalt pavement structure are obtained in this paper. The results show that the road surface temperature of the asphalt pavement in Tongliao, Inner Mongolia has a correlation with the atmospheric temperature, especially in spring and autumn. With the increase of the depth of pavement structure, the correlation between temperature and atmospheric temperature gradually becomes weaken, and it is basically out of the variation regularities of temperature at the pavement base.
