Abstract

In this study, the effects of the warm-mix asphalt additive content, asphalt type, and various mixing and test temperatures on the creep stiffness and cumulative micro-strain of asphalt mixtures were analyzed. In addition, the correlation between the rheological properties of the warm mix binders and mixtures were evaluated. Furthermore, a new methodology, namely, the hypotenuse length and sustainable angle method, was proposed to analyze the structural-environmental performance of the warm mix technology. The results showed that there was a close relationship between the properties of the asphalt binders and mixtures for various binder types and ageing states. Furthermore, the results indicated that this new methodology could be used by pavement and environment engineers to determine whether an asphalt mix is consistent with environmental regulations well as satisfying the structural performance requirements.
