Use of Plastic in Flexible Pavement

The use of plastic and related materials is increasing day by day due to grisly growth in population and over garbage and urbanization and changed life style leads to widespread littering of plastic on the landscape. Disposal of waste plastic is a serious problem globally due to their non-biodegradability and dangerous to human health, since these are not disposed scientifically and thus, create land and water pollution and air pollution after burning. Plastic is a curse to mankind but we used as a boon for mankind by using it as additives in road construction, it will proved to be the best solution over bad road condition. These days the techniques had been developed to use plastic waste for construction of bituminous roads and flexible pavements. In general bitumen is used as binder in road construction. Binding properties of this bitumen can be modified by mixing it with waste small plastic pieces. It can be used for construction purpose. Waste plastic coated the road aggregates and it can increase road strength. This modified bitumen mix and aggregates show better binding property, stability, density and more resistant to water thus increasing durability of roads with increased resistance to wear and tear of road.
