Abstract:
The main objective of this research is to investigate the potential use of reclaimed asphalt pavement (RAP) as an aggregate in portland cement concrete (PCC). RAP aggregate finer than number 4 (4.75 mm) sieve was treated as fine materials while those particles passing 3/4 inch (19.05 mm) and retained on number 4 sieve were treated as coarse aggregate. One set of concrete cylinders was prepared using 100, 75, 50, 25, and 0 percent RAP as coarse aggregate while fine aggregate was 100 percent RAP. Another set of samples was made using 100, 75, 50, 25, and 0 percent RAP as fine aggregate while coarse aggregate was 100 percent RAP. Samples were prepared using water to cement ratios of 0.40 and 0.50. In addition, control mixtures containing100 percent conventional aggregate (gravel and sand) were made for comparison purposes. Higher compressive strength was obtained as the percentage of RAP aggregate was decreased for all mixtures. The control specimens yielded the highest compressive strength. However, the strength was sufficient to qualify the use of RAP aggregate in concrete applications such as barriers, sidewalks, driveways, curbs, pipes, and gutters. Furthermore, mixtures containing RAP aggregate had enhanced ductility and showed excellent shatter resistance properties. Additional studies should investigate the use of additives and admixtures with RAP aggregate.
