Abstract

The importance of effective waste management has grown as technology has permeated every sector of the economy. Tyres from discarded cars, trucks, tractors, construction equipment, and off-road vehicles can be found in every state. When tyres are burned in the open, they release noxious substances such polycyclic aromatic hydrocarbons, dioxins, furans, and oxides of nitrogen, all of which contribute to air pollution. The nonbiodegradability of waste tyre rubber has made it a problem in recent years. The use of recycled tyre rubber in bitumen is explored in this paper to determine its potential. This is accomplished by layering aggregate and scrap tyre rubber and then applying varying concentrations of bitumen (5, 10, and 15 percent) to the topmost layer. In light of these findings, the research estimates the potential improvement in road pavement strength and economic success from switching to rubber from conventional asphalt.This not only lessens the environmental impact of old tyres, but it also lessens the need for traditional aggregate, a resource with finite availability. The problem of where to put all the trash that modern industry creates is now pressing. Many of these materials are not biodegradable, which might have negative effects on the environment. Besides natural sand and gravel, you can also use modified bitumen or granulated, crushed, or crumb rubber as fine stone aggregate. Crumb rubber from recycled tyres mixed with hot bitumen. It serves multiple purposes, including crack and joint sealing, chip seal coating, and asphalt pavement production when combined with heated mineral aggregate
