Paper Title:
Analysis on Anti-Crack Mechanism of High Elastic Asphalt Stress Absorption Interlayer
  Abstract

Based on the fracture mechanics, a finite element model of plane strain is employed to make a comparison analysis on the stress and strain field of reflective crack tip under the impacts of wheel load and thermal load of two different kinds of asphalt overlay—one overlay is set with stress absorption interlayer and the other is not. Results show that, under the impact of wheel load, the most unfavorable load position of reflective crack tip is 15cm of load center line away from the crack tip level. Under the effect of wheel load and thermal load, the stress and strain field of reflective crack tip has been greatly improved after setting the stress absorption interlayer and the stress intensity factor K and J-integral decrease obviously, which show that stress absorption interlayer plays a good role in anti-crack.
