PROCESSING AND STORAGE MAKE A DIFFERENCE : SHELTERED, BLENDED STOCKPILES LEAD TO BETTER USE OF RAP IN ASPHALT MIXES

With a recycling rate of 80%, hot-mix asphalt (HMA) pavement is one of the most recycled products in the U.S. This article focuses on the value of maintaining sheltered, blended recycled asphalt pavement (RAP) stockpiles and how this can reduce moisture content and the amount of heating required to dry it in an HMA plant, as well as boost the consistency of RAP for mixes. Fractionating, or reprocessing RAP into individual gradations can help improve the uniformity of the material and help control the mix properties and performance. The process, however, may not always be desired, since it can be costly, while simple screening and blending may be all that is needed to achieve consistency.
