The Regression Analysis of Corresponding Crack in Asphalt Pavement under Temperature Load

Abstract

By use of the theory of fracture mechanics, the plain-strain model is established to simulate the four-layer asphalt pavement of corresponding crack.. And then, applying the segmented integral method and power function form, the stretching stress intensify factors in the conditions that four limited layer combined status and different crack space are calculated and analyzed under the action of pavement and basement shrinkage. Moreover, the regression formulas are given which can meet requirements of the engineering regression equation precision.
