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.
