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.
