Comprehensive Review on Sustainable Pavement Materials Used in Flexible Pavements

Present the availability of the waste plastics is enormous, as the plastic materials have become part and parcel of daily life and also become a serious problem with the apparent disposal, leads to the environmental pollution. Utilization of waste plastic bags in bituminous mixes has proved that these enhance the properties of mix in addition to solving disposal problems. They either get mixed easily with Municipal Solid Waste and/or thrown over land area. Plastic waste which is cleaned and cut into a size such that it passes through 2.36mm sieve using shredding machine. The bitumen is heated and further added with plastic. Different grades of bitumen like 30/40, 60/70 and 80/ 100 are available on the basis of their penetration values. The steady increase in high traffic intensity in terms of commercial vehicles, and significant variations in daily and seasonal temperature demand improved road characteristics. If any improvement in the binding property, that can be utilized in further more. The plastic waste is mixed with hot bitumen and the new product can be used for the road construction. The use of innovative technology plays a vital role in the cost effective. It is not only strengthening the road construction but also increase the road life as well as will help to improve the environment.
