Abstract

In this paper, relax moduli for FRAC(FRAC) is studied. Using Sidoroff damage model for concrete, viscoelastic damage parameters are determined in order to evaluate the cracking control of FRAC pavement. The results obtained from the coupling analysis of using linear elastic damage mechanics and elastic fracture mechanics simultaneously show that the relaxation damage factor of FRAC pavement is reduced by 8.38% in comparison with the AC pavement, and the radius of damage zone and fracture zone for fiber-reinforced AC pavement are reduced by 66.34% and 64.16%, respectively.
