Abstract
Plastic waste is considered as harmful and hazardous in nature. If it’s not given proper consideration, it can turn into a disaster very quickly. The major problem related to plastic is its proper disposal. In today’s word plastic is being used everywhere from households, to shopping malls and even hospitals in the form of plastic cups, water bottles, for packaging materials etc. Various methods have been tried for the safe disposal of plastic to reduce its harmful effects on the environment. One such method of disposal is the utilization of waste plastic in bituminous mixes. Plastic waste is being utilized in the bituminous mixes in the form of HDPE, LDPE and EVA, PET etc. By utilization of plastic waste in the mixes, permanent strain gets lowered .Also the optimum percentage of bitumen is cut down by the utilization of Plastic waste in the mixes .The mixes having plastic exhibit better retained stability as compared to the normal mixes. Plastic wastes not only enhance the life span of a road but also reduces the cost of construction as well. In general, the optimum dosage of plastic for addition to bituminous concrete is kept as 6- 8%.This paper draws attention to the parameters which affect the performance of mixes when modified with Plastic.
