Sustainable Use of Sasobit in Warm Mix Asphalt: A Review

-Warm Mix Asphalt (WMA) is widely utilized in many parts of the globe due to its ability to combine the benefits of both hot mix and cold mix. Solidification is enhanced at lower temperatures when the adhesive's viscosity is decreased. On addition of additive, the asphalt mix is able to attain the properties of hot mix at the mixing temperature of a cold mix. To make the asphalt layer less vulnerable to low temperatures and have excellent permanent deformation qualities, the organic additives must be selected in such a manner that they melt at a lower temperature than predicted for the asphalt layer to reach the development site. Blends with the right qualities may be made in a more cost and environmentally-friendly way by using WMA expertise in asphalt. In recent years, there has been a rise in awareness of environmental and health risks in the construction industry. Various methods and additives have been developed by the industry to reduce the required assembly temperature of asphalt mixes, and this has resulted in the development of a new blend type known as Warm-mix-Asphalt (WMA). In this paper a review of contemporary practices of use of Sasobit in preparation of Warm mixes has been done.
