Astec Double Barrel® Green Warm Mix Technology

Staff | September 28, 2010

Astec's Double Barrel® Green is considered a warm mix process. Water, injected into mix, along with liquid asphalt cement, causes liquid asphalt to foam and expand in volume. Foaming action helps liquid asphalt coat aggregate at a temperature that is said to be about 50 degrees Fahrenheit less than traditional hot mix asphalt.
