Damage Model Analysis of SBS Modified Asphalt Mixture

The characteristic of the visco-elastic models and the damage models have been analyzed by the SBS modified asphalt mixture monaxial tension tests,and coupling becomes visco-elastic and damage models in succession.The fatigue damage characteristics of the SBS modified asphalt mixture and damage effect in terms of energy has also considered and a kind of fatigue damage models correlated with tensile strain level,the models and testing identically better have been built,which can predict the fatigue life of the SBS modified asphalt(mixture) under different tensile strain competence.
