Utilisation of municipal solid waste (MSW) is becoming a global practice in the struggle to control ever-increasing environmental pollution. Among all the constituents of the MSW produced in Pakistan, demolition and construction (D&C) waste and plastics contributes about 8% each (Pak-EPA, 2017).
RCA is a component of D&C waste that has poor structural performance. It can be concluded that plastic coated aggregates result in durable and long life asphalt concrete. This leads us to conclude that coating the aggregate will result in better durable long life asphalt concrete.
This research is based on the idea to enhance the strength of RCA for structural application by using another waste material (polyethylene plastic bags).
