Modification of Bituminous Mix by Adding Waste Polythene

Bituminous mixes are most commonly used all over the world in flexible pavement construction. It consists of asphalt or bitumen which binds mineral aggregate to make a homogeneous mix, laid down in layers and then compacted. In normal condition, conventional flexible pavements if designed and constructed properly as per the specifications, perform quite satisfactorily but the performance of bituminous mixes is very poor under temperature variation. Todays asphaltic concrete pavements are expected to perform better as they are experiencing increased volume of traffic, increased loads and increased variations in daily or seasonal temperature over what has been experienced in the past. Also these flexible pavements made up of bituminous materials are prone to deterioration by moisture.In the current investigation a fibrous and more moisture resistant bituminous mix is formed with the incorporation of waste polyethylene a locally available waste and non biodegradable compound. A comparison is drawn between conventional standard bitumen concrete and polyethylene modified bitumen concrete with varying polyethylene contents 0 , 2 , 4 , 6 , and 8 with bitumen binder 80 100 grade bitumen. Fly ash is used as mineral filler material. Waste polyethylene used as a modifier for the bituminous mixes for sustainable management of plastic waste as well as for improvement of bituminous mix. Marshall Method of proportioning mix design is to find the best percentage of polyethylene content to prepare mixes of different concentration. Yogesh Duddi | Er. V. S.
