Abstract: Road pavement failure is a challenging phenomenon for road maintenance agencies due to increase vehicular traffic. In developing countries, some pavements fail even before the completion and handing over site. During maintenance, the material removed from failed portions is regarded as waste and are disposed-off along road sides or in dumps. This paper investigates the possibility of recycling the material removed known as Reclaimed Asphalt Pavement (RAP) in concrete specimens as partial replacement of aggregate. RAP was used to replace the fine aggregates from 0-100 % at 20 % intervals. Water absorption, density and compressive strength tests were carried out. Increased workability, less water absorption and compressive strength of 75 %, 25 % and 28.4 MPa were achieved at 100 % replacement, 20 % and 40 % replacement levels respectively

Keywords: compressive strength, density, fine aggregate, Reclaimed Asphalt Pavement, workability
