Review on Usage of Waste Plastic in Bituminous Roads

This paper presents the review of the use of the plastic waste material in the road construction. Plastic cannot be easily decomposed by bacteria as it is a non-biodegradable. There is an increase in amount of waste plastic material due to day by day increment of industrialization and population. We can construct roads with the help of the plastic waste material. To withstand the stresses, the field tests demonstrated that the waste plastic material used after proper treatment as an additive would build up the life span of the road and can also deal with the environmental problems. As we change the amount of waste plastic in the bitumen the properties such as ductility, aggregate impact value, penetration value, Los angles values and softening point of bitumen changes with change in the amount of plastic waste. The roads laid out with the addition of the shredded plastic waste are much more durable compared to those roads which are laid out with normal bitumen. With the help of latest technology, the life span of the road is increased and construction cost is reduced. This technology helps to improve the environment also.
