This paper discusses the applicability of cohesive crack model to asphalt concrete as a composite material. A smeared crack approach to the cohesive crack model for linear viscoelastic material with rate-dependent cracking is presented in detail. Numerical examples with FEM simulation for uniaxial tension and beam bending tests were then given to demonstrate the capability of the approach.
