Effective Use of Waste Plastic as Bitumen Strength Modifier

Abstract

Type of shopping bag that are made from various kinds of plastic mainly from low & high density Polypropylene are carrier bags, shopping bags or plastic grocery bags. These are often called single-use bags as these are used to carrying stuff from a store to a home. The uses of these bags are increasing day by day due to rapid increase in population and growth in urban area. Plastic bags not only clog drainage systems but also contribute to flooding. Infrastructure of trash collection is less developed in Pakistan which causes a serious problem of littering. Plastics are friendly to consumer but are not environmental friendly due to their biodegradability. General methods to disposed waste plastic are either by incineration of materials or by way of land filling which are hazardous for human health and environment. This paper covers a new method to utilize waste plastic bags in modification of bitumen not to just effectively utilize waste plastics but also to improve strength properties of bitumen concrete mix of flexible pavement.
