Abstract

This paper describes a quick approach for quantification of the effects of a chemical warm additive and its interactions with temperature and aging on the rheological properties of asphalt binders using Response Surface Method. The central composite method was applied to design experimental programs for three test temperature conditions, namely; very high temperature (120°C–180°C), high temperature (46°C-82°C), and intermediate temperature (19°C–31°C). Rotational viscosity, G*/sin δ and G*sin δ were selected as parameters to assess the effects of a chemical warm additive named Rediset on the rheological properties of asphalt binders for different aging conditions. Evaluation of the effects of this additive on the transformed value of G*/sin δ at high temperatures indicates that additive content has significant effect on Ln(G*/sin δ). The results for intermediate temperatures show that this additive has a positive effect on G*sin δ of asphalt binders.
