摘要

Since the mid-1970s, tens of millions of tons of reclaimed asphalt pavement (RAP) have been used to produce recycled hot-mix asphalt (HMA) that has the same performance characteristics as HMA make with all virgin materials. Substantial savings have been achieved by using RAP in mixes. This report provides a review of the state-of-the-practice for the use of RAP, addressing the generation and handling of RAP materials, mix design techniques, handling RAP in the HMA facility (including environmental concerns), and placement and performance issues. Recycling HMA is a "win-win" scenario. The consumer wins with lower construction and rehabilitation costs without compromising quality, thereby stretching tax dollars and allowing more roads to be kept in better driving condition than if all virgin materials are used. The public also wins by a reduction in the volume of construction rubble in landfills and dumping sites. The constructions industry wins because higher volumes of production from the same fixed investment lowers business risk and keeps more people employed.
