Use of Plastic Waste in Construction of Roads

Abstract

Plastic is one of the toxic substance in nature. The major problem today is the disposal of waste plastics. These are non-biodegradable elements and can be removed only burning which will result air pollution and land pollution and hygiene problems. Instead of burning them or burying them we can use the plastic waste in construction of roads. This usage will be based on Economical, Technical, and Ecological criteria. Every year we produce some million metric tons of plastic waste. Theses wastes will be cleaned and cut into small pieces to get mixed well. These materials will also cost us less when compared to that of some traditional road materials. In road construction, they will get modified with the Asphalt, forming a mixture which can be used as a top layer for flexible pavements. If these wastes are used appropriately in construction of roads, the disposal and pollution problems can be controlled to a large extent. They can provide better binding property, Stability, Density, Durability and resistant to water. The use of this innovative technology will not strengthen the road construction but will also increase the life time and helps to improve the environment.
