Comparison Study on R.A.P with Old Asphalt Aggregate with Virgin Bitumen

The cost of paving materials rises as the restoration and building of highways progresses, and there is a scarcity of good quality materials. One of the most essential answers to this problem is recycling. This procedure creates a sustainable pavement by milling old components from the pavement and mixing them with virgin materials to create recycled combinations. Economic savings, reduced environmental impact, and natural resource conservation are all significant advantages of recycling. The primary aims of this research were to examine the effectiveness of recycled materials in asphalt mixes, to examine the impact of recycled materials on mixture behavior, and to examine the impact of including progressively older components into virgin mixtures. Old materials processed from the field, filler and 12.5 mm nominal maximum size of virgin aggregate, and virgin bitumen of (40–50) penetration grade have been modified and utilized to make recycled mixes. There were a number of analyses performed on the mixes used in this study. The Marshall Stability (3 specimens). In the case of recycled asphalt pavement the recycled combinations including 100% virgin/old components and old with new aggregate and old aggregate with new bitumen, Recycled. The performance of mixtures with old aggregate content was good. When compared to blends with old bitumen, the percentages of variance for mixture properties were features of (Marshall Stability), and the reduction in mixture properties was in an acceptable range.
