As reclaimed asphalt pavement (RAP) usage continues to increase as a way for producers to keep costs down while utilizing stockpiles of reclaimed asphalt pavement, Astec has increased the ability of its signature Double Barrel drum dryer/mixer to handle RAP. The Astec Double Barrel HR includes enhancements to the drum which allows use of up to 65 percent RAP.
“The Double Barrel HR is a key product in the Astec line. It fulfills a need for those producers who already run high percentages of RAP and in whose markets the trend toward running more recycle is expected to increase,” says Astec president Malcolm Swanson.
