To Study Experimental Analysis of Replacement of Aggregate with Recycled Concrete Aggregate in Bituminous Concrete - A Review

Abhishek Meshram, Dr. Alok Goyal

Abstract: The propose of this research work is to use recycled concrete aggregate (RCA) in replacement of fresh aggregate in bituminous concrete to provide good strength, made economic roads & environment friendly. In bituminous concrete aggregate is replaced by RCA with 0%, 5%, 10%, 15%, 20% to observe behaviour of bituminous concrete. We made 3 sample of each percent and take average of values. The experimental results shows that when we replace the fresh aggregate with recycled concrete aggregate in 0%, 5%, 10%, 15%, 20% then its behavior about Marshall stability, Marshall flow, Air void, Percent volume of bitumen (Vb), Void in mineral aggregate (VMA), Void filled by bitumen (VFB).
