Hei-way general purpose recycled asphalt material (RHM). Final report
Utilization of Reclaimed Asphalt Pavement (RAP) in paving projects is a popular concept. It conserves material and can often provide an economical alternative to using virgin materials. The research summarizes the utilization of about 8000 tons of RAP in a project in Armstrong County (SR 3011 and SR 3013) using a proprietary process by Heilman Pavement Specialities. The mix is called Recycled Heilman Mix (RHM), which is prepared using a proprietary blend of asphalt cement (AC-5) and a rejuvenator mixed with equal weights of RAP and virgin aggregates in a batch-type pugmill. A control mix was produced by using 9.6 gallons per ton of E-5 emulsion and a blend of equal weights of RAP and coarse aggregates. The construction of the two sites were completed in September 1988 without any significant problems. A three-wheeled roller, ballasted rubber-tired roller and a second 1-ton tandem roller was used for compaction. There were no significant construction problems. RHM performed well on this project. The method of recycling asphalt pavements appears to be viable. RHM is stockpileable. Although RHM was 40 to 50 percent more expensive on the project, the life cycle costs on larger projects can be more competitive, especially when the cost of a seal coat is either avoided or delayed on RHM jobs when compared to E-5 mixes as control.
