Abstract: Concrete is the basic material in all construction works and coarse aggregates constitute more than 50% of the mix. But the procurement and generation of natural aggregates is getting difficult day by day because of lack of natural source and environmental effects. In search of alternative for natural aggregates, lead to the usage of Reclaimed Asphalt Pavement aggregates, which are produced abundantly due to replacement of Flexible Pavements with Rigid Pavements in India. This study is taken up to determine the variation of different properties of strength and flexural strength of concrete with natural aggregates and RAP aggregates. The cubes will be casted and tested for Strength and Flexural Strength is also determined by casting beams. The results can be analyzed to identify the importance of RAP aggregates for its effective and efficient usage for present scenario of India. The RAP Aggregates are procured from Kanmangla flyover, Bangalore. And it is checked for the effective utilization in Concrete. RAP aggregates are replaced with Natural Aggregates by 50% and 25% and evaluated.

Keywords: concrete, flexural strength, compressive strength, reclaimed asphalt pavement (RAP)
