The Double Barrel dryer/ mixer is a combination aggregate dryer and hot mix asphalt mixer with high productivity and low operating costs. Units have the ability to run up to 50 percent reclaimed asphalt pavement (RAP) with no added fuel cost, and feature a unique design that allows for keeping RAP and virgin aggregate separate until the mixing phase of production. While the virgin material is dried in the main drum, RAP is injected into the outer mixing chamber. Because the RAP never comes into direct contact with the hot gas stream of the dryer, the Double Barrel drum mixer produces mixes with up to 50 percent RAP, with no more blue smoke emissions than all-virgin mixes.

The Double Barrel dryer/mixer is a combination aggregate dryer and hot mix asphalt mixer with high productivity and low operating costs. The ability of the Double Barrel drum mixer to run up to 50 percent reclaimed asphalt pavement (RAP) with no added fuel cost makes it especially valuable in today’s market of fluctuating fuel and liquid AC prices.
