Warm mix asphalt technology: An up to date review

Abstract The purpose of the current review is to give an insight into various Warm Mix Asphalt (WMA) techniques in pavement engineering. The idea is to provide a comprehensive overview of this technology that may serve as a basis for engineers and practitioners to structure the entire processes, associated with the design and construction of roads, under healthier and safety-oriented working conditions while following an environmentally friendly conscious approach. This manuscript provides an up-to-date review of WMA technologies. The paper also presents and compares several studies on the most common additives, mix design and environmental benefits of this production method. Also, this review discusses the improvement in physical, mechanical properties and durability of pavement designed with WMA mixtures.
