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 mainly durability of concrete pavements 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
NICE, Bangalore. And it is checked for the effective utilization in Concrete Pavements. RAP aggregates are replaced with Natural
Aggregates by 100%, 75%, 50% and 25% and evaluated. Also the fatigue models are developed by testing the beams under repeated
loadings by considering stress ratio of 65%, 75% and 85%.
