Cold mix asphalt: An overview - ScienceDirect

2021-1-20  Depending upon the production temperature asphalt mix is broadly divided into 3 categories i.e. hot mix asphalt (HMA), warm mix asphalt (WMA) and cold mix asphalt (CMA). First and most widely used asphalt mix is HMA for the construction of pavement. HMA is prepared at very high temperature which goes up to 190 ° C (Al-Busaltan et al., 2012).
