SOLVE PROBLEMS AND CUT COSTS WITH COLD-RECYCLED ASPHALT

Cold in-place asphalt recycling (CIR) has made steady technical progress in recent years, resulting in improved pavements and cost savings. However, according to asphalt expert Jon Epps at the recent meeting of the Asphalt Recycling & Reclaiming Association (ARRA) in Florida, more research is needed in mix design, structural strength measurements, life cycle costs, field density control methods, and lab curing techniques. Solutions to the aggregate stripping problems with CIR, according to Epps, are to be found in the potential of lime and portland cement as stabilizers, improved construction quality control of mixing the material, and liquid antistripping additives. Guidelines offered by Epps for CIR include the following: Mill and recycle to a depth of 2 to 4 in.; Softening of the material may occur in 2 to 3 days and re-rolling should be practiced; Recycled material should cure 2 to 3 hours before traffic.
