As RAP usage continues to increase as a way for producers to keep costs down while utilizing stockpiles of reclaimed asphalt pavement, ASTEC, Inc., an Astec Industries company, 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% RAP. A 1/8 model of the new high RAP Double Barrel drum were on display during the ConExpo 2014 tradeshow in Las Vegas.
ASTEC President Malcolm Swanson says, “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.”
