WARM MIX ASPHALT (WMA) 

In 2010, BoDean Company made investments to become the first batch plant asphalt producer in California to shift away from Hot Mix Asphalt (HMA) production to Warm Mix Asphalt production (WMA) without using chemical additives.

Typically, asphalt must be produced at temperatures over 320 degrees Fahrenheit. These high temperatures create “blue smoke,” which can be easily detected by the odor associated with asphalt paving projects. Higher temperatures also lead to greater oxidation, lowering a pavement’s life span. However, by injecting atomized water molecules into the hot binder oil during the production process, we can reduce the temperatures to below 275 degrees, thereby eliminating the harmful gases (blue smoke) and virtually eliminating the obnoxious odors associated with paving. This greatly reduces CO2 gases and the energy consumption associated with the production process.
