Abstract

This paper provides an extensive literature review especially on Warm Mix Asphalt (WMA) technology. A wide considerations of construction example, current issues and future research topics on WMA were performed. It is well known that WMA is an environment friendly, next generation asphalt pavement technology. In order to understand the blowing agent in the WMA method, It summarizes the blowing agents principle, manufacturing method, selection criteria, and blowing mechanism, and summarizes the characteristics of blowing agents commercialized domestically and abroad. Since many Blowing agents have already been developed and used abroad, continuous research and development is needed to produce Blowing agents with only domestic technology. Based on this paper, readers can understand the Blowing agents principle and the types of Blowing agents commercialized well in many specialized areas.
