Abstract
The use of Reclaimed Asphalt Pavement (RAP) aggregates in road construction reduces both the amount of construction debris disposed of in landfills and the rate of natural resource depletion. This paper presents the results obtained from a series of repeated load triaxial tests conducted on both untreated and treated RAP aggregates. Test specimens were compacted at density corresponding to optimum moisture content with different dosages of ordinary Portland cement (Type I/IT) with fibrillated polypropylene fibers. The resilient moduli of untreated aggregates varied between 180 and 340 MPa and that of cement-fiber treated aggregates varied between 200 and 580 MPa. Effects of cement and fiber dosages on the moduli enhancements of RAP aggregates are explained. Structural coefficients of these materials are also presented.
