Characterization of Shredded Waste Plastic on Warm Stone Mastic Asphalt
The heavy traffic on the national highways demand for durable bituminous mixtures for long run. To serve this purpose, the Stone Mastic Asphalt (SMA) can be used, which is a gap-graded mixture with high binder content. In this study, the stone mastic asphalt was prepared using viscosity grade (VG) 30 binder and stabilized with shredded waste plastic (SWP) by varying percentage of plastic by the weight of total mix (0–1% with an increment of 0.2%) to prevent drain down characteristic of the binder. The experimental study was carried out to assess the Warm SMA stabilized with shredded plastic waste and subjected to performance tests including Marshall mix design, Indirect tensile strength by IDT setup to evaluate the performance of Warm SMA. It was observed that optimum bitumen content for the desired WSMA mix with SWP is 6.1%, for the optimum dosage of shredded waste plastic as 0.8% of the total mix. The lowered mixing and compaction temperature were determined for Warm SMA and Tensile strength ratio (TSR) was determined for the chosen temperature. However, unit cost of shredded waste plastic is lesser than that of cellulose fibers. Hence, the designed WSMA mix with shredded waste plastic is cost effective as well as eco-friendly.
