More RAP in HMA: Is it Worth It? The 2007 Virginia RAP Initiative

In this article the author describes the promotion of reclaimed asphalt pavement (RAP) for use in hot-mix asphalt (HMA). Data from the Virginia Department of Transportation (VDOT) are used. The total material cost for VDOT’s “virgin” Superpave is $41.20 per ton, with a $3.72 per ton savings if 10 percent RAP is used instead of unreclaimed asphalt. If 30 percent RAP is used instead, VDOT saves $11.76 per ton. When it is taken into account that many organizations produce hundreds of thousands of tons of HMA per year, the author explains that integrating RAP into an agency’s plan is the largest potential cost saving measure currently available. A four-step plan is presented that is currently being used by VDOT to increase its use of RAP. The first is to make the initiative multi-level, with implementation occurring in all sectors of the department’s business. Second is to learn from mistakes and successes in the past with regard to RAP. Third is to visually demonstrate the efficacy of its use. And, lastly, ensuring a high level of quality control (QC) is essential to the program’s success.
