| Abstract | Bituminous mixtures exhibit complex visco-plasto-elastic behavior. However, implementation of purely linear viscoelastic properties at this early stage in the implementation of mechanistic based models used in the analysis of flexible pavements is a reasonable starting point. This simplifying assumption requires that testing of asphalt concrete be performed at low strain amplitudes where the material response remains linear visco-elastic. The material testing system included in the NCHRP 1- 37A project adopted the dynamic modulus as the input to the M-E model that accounts for HMA stiffness, a property necessary for performing structural analysis to determine the state of stresses and strains in the asphalt concrete layer. The model uses the established state of stresses and strains to predict rutting and fatigue and other distress types using performance models incorporated in the software. |
