HOT-MIX RECYCLING: EQUIPMENT CONSTRUCTION, DESIGN, RESULTS

Modified equipment now is readily available for reclaiming and recycling asphalt pavements. Mix design procedures exist that assure the proper proportioning of reclaimed asphalt pavements (RAP), recycling agents, and untreated aggregate. Savings in construction and material costs can be significant for properly designed and constructed recycling projects. Despite these advantages, recycling has not been readily accepted. Some of the reasons for this slow acceptance and some of the elements necessary for the recycling process to be successful are discussed. Existing information is reviewed that supports the fact that the properties of recycled mixes and virgin asphalt mixes are very similar. Guidelines are offered on the handling and quality control of RAP. Suggestions are made on plant modifications to maximize production and minimize air quality problems in the manufacture of recycled asphalt mixes.
