Bituminous mixes are most commonly used all over the world in flexible pavement construction. It consists of asphalt or bitumen used as a binder and mineral aggregate which are mixed together, laid down in layers and then compacted. Under normal circumstances, conventional bituminous pavements if designed and executed properly perform quite satisfactorily but the performance of bituminous mixes is very poor under various situations. Today's 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. In addition, the performance of bituminous pavements is found to be very poor in moisture induced situations. In the present study waste polyethylene which has been easily obtained are used, in dry form with the aggregates like a fiber in a bituminous mix. A comparative study is carried out between 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. Using Marshall Method of mix design the optimum polyethylene content have been determine of the different type of the mix.
