UTILIZATION OF WASTE PLASTIC BAGS IN ROAD CONSTRUCTION
Abstract:
Disposal of waste plastic bags from the domestic has become a become a major problem to the agencies in the cities. The waste plastic bags available in the dogmatic waste plastic mainly consist of lowdensity polyethylene .plastic bags dumped in the dustbins find their way into the drainage system and clog them. Often, these are burnt along the roadside ,which produces fumes causing air pollution.
This paper emphasizes on the laboratory evaluation on the bituminous mixes for utilization of plastic bags in the road construction.the laboratory performance studies were conducted on bituminous concrete mixes a dence mix used as a surface course in road construction.the laboratory studies proved that waste plastic enhances the property of the mix in addition to providing for the way for it’s disposal in a useful way. In the present investigation,comparision was made between convention bituminous concrete mix and the mix modified with waste plastic . The results indicated that the strength properties of the mix with waste plastic were better when compared with a conventional mix. The fatigue life was doubled using waste plastic in the mix under laboratory condition.
INTRODUCTION:
Disposal of waste has become a grate problem in cities .Disposal of waste plastic bags is one such menace. The main problem with plastic is, it will be thrown on roads and dumped in dustbins and drains. The waste plastic bags, which are dumped, find their way into drainage systems and aesthetic problems. One of the promising option currently under investigation is the use of such waste plastic to modify the bituminous mixes used for paving roads .These polymers (plastic) need to be process separately, as they can be obtained from waste plastic, which are reduce throughout the world in several million tones every year .These plastic will improve some properties of the bituminous mix and also solve environmental problems.
