Investigation on Bitumen Modification Using Nitrile Butadiene Rubber and Low-Density Polyethylene

Abstract

Study of feasible usage of waste plastic in addition with Nitrile butadiene rubber to enhance the engineering and rheological properties of bitumen binder. Rheological properties impact the performance and service life of bitumen greatly. Different percentages of Nitrile butadiene rubber were introduced as an additive in base bitumen binder along with Low density polyethylene. Nanoclay was used as compatibility agent. Waste plastic percentage was restricted to 3% where as NBR was used by 14 % by weight of bitumen. The nano-composite yielded softening value increased by 34% and recovery percentage was improved by 7.3 %.
