Warm Mix Asphalt (WMA) technologies allow significant lowering of the production and paving temperature. By reducing the viscosity of bitumen and/or increasing the workability of mixture, WMA technologies can reduce the temperature up to 80 degrees below the temperature of conventional Hot Mix Asphalt without compromising the performance of pavement. This promises various benefits over HMA, e.g. lowering the greenhouse gas emissions, lowering energy consumption, improved working conditions, better workability and compaction, etc. However despite the promising performance in...
