Establishing And Checking The Temperature And Humidity Coupled Model About Asphalt Pavement Structure

摘要

Temperature and humidity of the pavement affected the performance of the pavement structure as the key factor. In this paper, we used the classic migration theory of temperature and humidity, and considered the actual characteristics of the asphalt pavement structure, established a temperature and humidity coupled equations for the asphalt pavement and got the calculation model by discretization, determined the boundary conditions and calculation parameters. Compared the calculation results with the actual results, we found that the model has high accuracy, it was able to meet the requirement of the predictive analysis about internal temperature and humidity of asphalt pavement in the work of researching and designing.
