Warm Mix Asphalt (WMA) production technologies allow lowering the production and paving temperature of the conventional Hot Mix Asphalt (HMA) by at least 20°C without compromising the performance of asphalt. This promises various benefits over HMA, for example, allows to reduce the energy consumption, thus lowering the greenhouse gas emissions, permits to extend the paving season, attain better compaction, provides longer haul distances etc. However, in order to reach widespread implementation of WMA, it is necessary to provide enough information to the decision makers on the benefits of this technology. This article presents overview of different WMA products and production principles, benefits and drawbacks associated with the technologies. A total of fifteen products that were found to be used in Europe are reported in the paper. However, not all of the technologies are suitable for Latvia, because of the necessary economical investments, climate, local legal provisions and the industry traditions. Potentially most favourable technologies for Latvian circumstances are analysed with the reference to local road specifications.
