Abstract

Abstract

In order to compare the stress varieties in surface and base caused by different humidities, temperatures and base crack states, pavement models with different crack depthes, widthes and spaces were established by 3D finite element method. Using the test parameters of base, the maximum stress, stress distribution and the influence on asphalt pavement were analyzed under water losing condition and temperature decreasing condition for cement stabilized macadam base asphalt pavements with different base crack states. Analysis result indicates that, for new base, the influence of water losing on shrinkage stress is more remarkable than that of temperature dropping; it is the most favorable condition for reducing base crack when base modulus is about 4 000 MPa; whether water losing or temperature decreasing, the most marked factor of influencing structural stress is each layer-self modulus; when joint state between base and sub-base is bad, the tensile stress in surface bottom is larger than that in continuum state, and base crack easily reflects to pavement surface.
