Abstract

Waste plastic polypropylene is increasing due to development activities and changes in lifestyle, leading to widespread littering on the landscape. The study investigates the polypropylene waste plastic potential using an asphalt concrete modifier. The compressive strength tests conducted to examine asphalt concrete wearing course mixture strength using Modified Buton Asphalt (MBA) binder with and without waste PP (Plastic Polypropylene) based on AS-2891 standard. In these tests, mixture condition with 1% and 2% asphalt binder by total weight, were chosen as an additive for AC-WC (Asphalt Concrete Wearing Course) mixture to improve the compressive strength values. The results showed that the treated AC-WC mixture compressive strength was higher as compared to the untreated AC-WC mixture. The results denoted that waste PP can coalesce with the MBA to provide much proper binder and result in higher resistance to compressive load.
