As Reclaimed Asphalt Pavement (RAP) usage continues to increase as a way for producers to keep costs down while utilising stockpiles of reclaimed asphalt pavement, ASTEC has increased the ability of its signature double barrel drum dryer/mixer to handle RAP. The ASTEC double-barreled HR includes enhancements to the drum which allows use of up to 65 per cent RAP. A 1/8 model of the new high RAP double barrel drum was on display during the ConExpo 2014 trade show in Las Vegas.

ASTEC President Malcolm Swanson said, ?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.?
