Analysis of Thermal Stress of Asphalt Pavement on Lean Concrete Base
Thermal stress has been an important parameter used in the analysis of the new pavement design. For the purpose of studying the thermal stress for the asphalt pavement of lean concrete base, first of all, three–dimension finite element model of the asphalt pavement is established. The two main objectives of the paper are investigated. One is analysis for thermal stress of lean concrete base, and the other is analysis for thermal stress of asphalt surface. The results show that thermal stress of lean concrete base increases, decrease and increase with increase of base’s thickness, surface’s thickness and ratio of base’s modulus to foundation’s modulus respectively. So far as the asphalt surface is concerned, maximum shearing stress and maximum tensile stress, which are caused by temperature difference, are evident in asphalt surface which is located in transverse contraction joint of lean concrete base of asphalt pavement.
