Evaluation of Rediset for use in warm-mix asphalt: a review of the literatures

Abstract

This literature review paper presents the effects of a chemical warm mix additive, named Rediset on the rheological properties of asphalt binders, laboratory performance of asphalt mixtures, field behaviour of constructed road sections, energy consumption and air pollution, physicochemical properties of asphalt binders and behaviour of asphalt mortar. The rheological effects of Rediset on asphalt binder were evaluated from the viewpoint of very high temperature properties (viscosity of asphalt binder and workability of asphalt mixtures), high temperature properties (rutting resistance of asphalt binders and mixtures), intermediate temperature (fatigue behaviour) and also low temperature cracking properties. Other topics such as the mechanisms of temperature reduction by Rediset, storage stability of Rediset modified binders, moisture susceptibility, mix design issues, volumetric properties and economic benefits were also investigated. The information reported in this paper will help decision makers to appropriately select, apply and evaluate this warm additive type. In addition, researchers can identify gaps in existing knowledge for future research.
