USE OF WASTE POLYTHENE IN MODIFICATION OF BITUMINOUS MIX FOR DBC– A REVIEW

Bituminous mixes are most typically used everywhere the world in flexible pavement construction. It consists of asphalt or bitumen (used as a binder) and mineral combination that is mixed along, set down in layers and so compacted. Under traditional circumstances, standard bituminous pavements if designed and executed properly perform quite satisfactorily; however, the performance of bituminous mixes is extremely poor under varied situations. Today's asphaltic concrete pavements are expected to perform higher as they're experiencing the increased volume of traffic, accrued loads and increased variations in daily or seasonal temperature over what has been experienced within the past. Additionally, the performance of bituminous pavements is found to be terribly poor in wet induced situations. Considering this plenty of labour has been done on the utilization of additives in bituminous mixtures and as well as on modification of bitumen. Plastics are everywhere in today's lifestyle and are growing rapidly throughout particularly in a developing country like India. As these are nonbiodegradable there is a major problem posed to the society with regard to the management of these solid wastes. Low density polyethylene (LDPE) has been found to be a good modifier of bitumen. Even, the reclaimed polyethylene originally made of LDPE has been observed to modify bitumen.
