        abstract = {In the process of recycling flexible pavement, a significant quantity of Reclaimed Asphalt Pavement (RAP) aggregate is produced, which ends up being disposed of both legally and illegally in nearby communities, creating various challenges for agencies. The use of these aggregates in cement concrete pavements appears to be an innovative approach and could offer numerous socio-economic and environmental advantages. In this research, standard concrete is produced by utilizing recycled aggregates combined with the addition of silica fume as an admixture in concrete. However, little research has been done to examine the potential of incorporating RAP Aggregates into concrete mix to replace conventional aggregate. The present study focused on the evaluation of mechanical properties of concrete mix made with real RAP materials through laboratory experiments. Two types of RAP materials (coarse and fine RAP) were used to replace an equal amount of conventional coarse and/or fine aggregate.The concrete mix is designed for target strength of M40 MPa. Coarse aggregate were partially replaced with RAP aggregate at 30 %, 45 % and 75%. The relative parameters influencing the strength of concrete were studied in terms of RAP aggregate and silica content respectively. Test results reveled concrete produced with 45% of RAP aggregate tend to reduce the strength by 15% whereas addition of silica fume into the matrix improved the physical, mechanical and chemical properties of concretes containing RAP. When the RAP aggregate is increased by more than 30%, a noticeable drop in compressive strength is observed.},
