Sales are hot--so is asphalt
Roads & Bridges
August 2002
Margaret Cervarich
The Victor facility of Rochester Asphalt Materials recently earned the Diamond Achievement Commendation for Excellence in Hot Mix Asphalt Plant/Site Operations from the National Asphalt Pavement Association (NAPA). In 1996 a developer came to the company with the idea of putting in a shopping mall that would house stores like Target and Home Depot. Rather than go through the permitting process at a new location, Rochester Asphalt Materials worked out an arrangement with the mall that allowed them to move the plant to one side of the property. Because they remained at their old location, the existing permits covered them.

Handling RAP in an HMA Facility
Roads & Bridges

Dale Decker
In the HMA facility, the RAP must be dried and heated prior to mixing into the HMA. Heat transfer to the RAP can be accomplished either conductively or convectively. Conductive heat transfer is used in almost all batch facility applications and when RAP is introduced in counterflow dryers while convective heat transfer is used in conventional batch plant aggregate dryers and parallel-flow drum mixes.
