Understanding Warm-Mix Asphalt

Warm-mix asphalt (WMA) allows producers to lower the temperatures at which the material is mixed and placed on the road. Such reductions have obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases. In addition to the environment, other benefits include better compaction on the road, the ability to haul paving mix for longer distances, and the ability to pave at lower temperatures.
