STUDY ON USE OF WASTE POLYTHENE BITUMINOUS PAVEMENT MIXES

Abstract

Use of waste material in road construction is becoming more popular as a way to reduce the 
environmental effect of building roads across the world. These materials and technologies have been 
developed in the highway infrastructure to determine their appropriateness for the design, building and 
maintenance of pavements. One of these is polythene. Also taking into account the environmental 
element, the damage to the environment is huge as more and more polythenes is used in everyday 
operations. Carry bags and food coverings made of polythene are becoming more and more 
commonplace. Main emphasis of this research is to utilise the plentiful waste poylthene that may be 
used cheaply and easily. The use of polythene in the sub-base course of the pavement will provide 
strength and is environmentally good when these waste materials are used in road building. Bitumen 
and tar are both bituminous binders used in pavement construction. Hydrocarbon substance derived 
from the fractional distillation of crude oil known as bitumen is accessible. Bituminous materials are 
often utilised in highway building because of their ability to bind and seal off water. Plastic has become 
the best buddy of the average guy. It may be used in any industry. Packaging accounts for almost half of 
all plastic waste. Carry bags, cups, thermopolis, and foams are the most common plastic packaging 
materials. Polymers such as polyethylene, polypropylene, and polystyrene are used in the production of 
these products. Polyvinyl chloride (PVC) tubing and wires are used. Thrown away or discarded, these 
items end up in landfills or combined with municipal solid waste (MSW). The non-biodegradability of 
plastic means that it is difficult to dispose of and generates societal issues that contribute to 
environmental degradation. One of the most pressing issues facing modern civilization is the pollution 
created mostly by plastics. Bituminous mixtures containing 'Zycothermal', a chemical stabiliser, may be 
made by substituting 8 percent, 10 percent, and 12 percent of bitumen by weight of plastic for optimal 
bitumen content. Straight run bituminous mix is compared for stability and flow.
