Warm Mix Asphalt

Contact us for sales or technical advice on this product


Roadstone Warm Mix Asphalt (WMA) is a bituminous mixture that incorporates technology that allows the material to be manufactured at lower production temperatures. This reduces the amount of fuel required to dry and heat the aggregates in the bituminous material, resulting in lower energy consumption and lower CO2 emissions.

The incorporation of this technology means that the performance characteristics of the Warm Mix Asphalt are the equivalent of a Hot Mix Asphalt (HMA) despite being produced at a lower temperature. Warm Mix Asphalt is a “greener” more environmentally sustainable option.
