USE OF PLASTIC WASTE IN PAVEMENT CONSTRUCTION

Civil Engineering

Pervious pavement blocks are noteworthy concrete blocks that allow infiltration of storm water through the ground surface into the soil. Pervious pavement blocks are a recognized runoff-reducing substitute for normal pavements in development of sustainable parking areas, sidewalks, gardens. The cavities present in the previous pavement blocks allows water to percolate through it. The compressive strength of the pervious pavement block is lesser than that of the impervious pavement blocks due to the presence of voids. Also, the strength of plastic based pervious concrete is less than the strength of pervious concrete made using cement as plastic possesses less adhesive property than cement. The waste plastic is shredded & coated over aggregate & mixed with hot bitumen and resulted mix is used for road/pavement construction. This will not only strengthen the pavement but also increases its durability. This innovative technology will also be suitable for Indian hot-humid climate. It is eco-friendly as well as economical. In this paper, we have discussed the method of using plastic waste in construction of roads and how it is better than the ordinary roads.
