Warm Mix Asphalt (WMA) – Asphalt Pavement

Hot Mix Asphalt (HMA) is the traditional process for constructing asphalt pavements. HMA is manufactured in a central mixing facility (typically called a hot mix plant) and consists of high quality aggregate and asphalt cement. The two are heated and mixed while hot to completely coat the aggregate with asphalt cement.

Warm Mix Asphalt - Home

Warm-mix asphalt technologies allow the producers of asphalt pavement material to lower the temperatures at which the material is mixed and placed on the road. Reductions of 50° to 100° Fahrenheit have been documented. Such drastic reductions have the obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases.

The second type is known as asphalt treated permeable bases, and it is used specifically for its ability to drain water away from the top layer of pavement. It is used as a base for dense-graded asphalt and Portland cement surfaces. Warm Mix Asphalt Warm mix asphalt or WMA is currently used in about 30 percent of all paving projects.
