Load Stress of Roller Compacted Concrete Base in Flexible Pavement

In order to analyze load stress of roller compacted concrete base of asphalt pavement, first of all, three dimension finite element model of the flexible pavement is established. The main objectives of the paper are investigated. One is calculation for stress of roller compacted concrete base in asphalt pavement, and the other is analysis for relationship between load stress of roller compacted concrete base and parameters, such as thickness, modulus. The results show that stress, which is caused by load that is located in the middle of longitudinal joint of roller compacted concrete base of asphalt pavement. Maximum load stress decrease, decrease and increase respectively with increase of the surface's thickness, base's thickness and ratio of base's modulus to foundation's modulus.
