Analysis on Stress of Pavement with Different Crack Statuses in Base

In order to compare stress responses in pavement structure with various base states under vehicle load, finite element method is used to establish the model for different projects, and then distribution of stresses in semi-rigid base asphalt under various horizontal loads and interbeded conditions were calculated. The analytical results indicate that: 1) interlaminar combination is an important factor to influence evolution of base crack; 2) both tensile stress and shearing stress increase dramatically when joint condition between surface and base is bad; and 3) those cracks whose depth is less than base thickness may reflect to pavement surface quickly. Therefore, to spread asphalt pavement after shrinkage cracks in base were developed and treated can reduce and postpone reflecting crack.
