Performance of Chemical WMA Mixtures – A review

Abstract

In recent years, a new approach called WMA technology is developed, which include reduces binder viscosity and accordingly
allows lower temperatures for mixing and compaction. This technology gives several benefits, such as reduce emission, less odor,
and energy saving. This study gives a comprehensive review on the use of WMA with chemical technology. In addition, give an
introduction to use chemical additives into the bitumen, in order to understand the application of these additives, the problems,
benefits and how they act are reviewed.
