Analysis of Warm Mix Asphalt (WMA) Implementation in Latvia

WMA is a relatively new technology that allows significant lowering of the production and pavement temperature of conventional hot mix asphalt (HMA). WMA promises various benefits, e.g. lowering the greenhouse gas emissions, lowering energy consumption, improved working conditions, lower binder viscosity, better compaction, etc. These technological advantages of WMA allow to use it not only as substitute for conventional HMA by applying the same asphalt specifications, but also to use it in circumstances, where usage of HMA would not be eligible
