Warm Mix Asphalt Using Sasobit in Cold Region | Cold Regions

The potential of using Warm Mix Asphalt (WMA) in reducing the energy consumption of HMA is becoming more and more attractive nowadays. The goals for the WMA are to lower mixing and compacting temperatures and use the same Hot Mix Asphalt (HMA) plants to produce mixes that still meet specifications.

Figure 23 shows a pneumatic feeder used to meter Sasobit into a drum plant. The Sasobit is introduced into the mixing chamber at about the same point that the binder is introduced (or where fibers would be introduced). Since 1997, more than 142 projects totaling more than 10 million tons of mix have been paved using Sasobit.
