USE OF WASTE PLASTIC IN CONSTRUCTION OF BITUMINOUS ROAD: A Review

Waste plastics and their disposal are a major threat to the environment, resulting in pollution and global warming. The use of plastic waste in bituminous mixtures increases its properties and strength. In addition, it will also be a solution to the disposal of plastics. The waste plastics used are polyethylene. The waste plastic is crushed and spread on aggregate and mixed with hot bitumen and the resulting mixture is used for road construction. This will not only strengthen the pavement, but also increase its durability. Titanium dioxide is used as a smoke absorbing material that absorbs smoke from vehicles. This innovative technology will benefit India’s hot and humid climate. It is economic and ecological. In this article, we have discussed the soil properties that need to be considered in roadway design, roadway design, flexible construction process. Therefore, this study is expected to help minimize the pollution caused by plastic and thus develop an environment-friendly technology. The aim of this paper is to review the relevant literature that published related to use of waste plastic in construction of bituminous road. By studying 10 research papers, focused on various strategies, tools, techniques and methodologies.
