Warm Mix Asphalt - About WMA

Warm-mix asphalt allows 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 degrees Fahrenheit have been documented. Such drastic reductions have the obvious benefits of cutting fuel consumption and decreasing the production of greenhouse gases.

Hot Mix Asphalt Vs Warm Mix Asphalt - Zydex Industries

2021-8-13  Warm mix asphalt (WMA) uses a process called “adhesive bonding” to create an even, strong bond between the aggregate and binder that allows it to be put down at about 180 degrees Fahrenheit without cooling. HMA is produced and transported at a higher cost than WMA because of the higher temperatures needed to prevent it from solidifying.
