A Review on Utilization of Industrial Wastes and Byproducts in Highway Construction
Keywords:Industrial wastes, Byproduct, Environment, Highway construction
Industrial waste and their disposal are currently a major issue in India while highway materials such as crushed stone, sand, and gravel are in high demand, yet economic resources are often scarce. The development of significant amounts of industrial waste necessitates not only its disposal, but also its treatment prior to disposal in order to reduce contamination of soil, water, and air. Given the sharp increase in the number of factories and industries, it is important to understand the advantages of waste materials that can be recycled and used in various ways. Adopting these waste materials from industry for highway construction is the best use for them. These aspects are also a factor influencing production costs. So, the current study is concerned with the utilization of waste materials in highway construction, including waste tires, waste glass, retrieved paving materials, slag and ashes, construction rubble, and sewage waste. Based on technical, environmental, and economic factors, reclaimed paving materials, coal fly ash blast furnace slag, boiler slag, steel slag, and rubber tire have significant potential to replace conventional materials in various applications in highway construction and should be projected for future construction. Increased use of wastes and byproducts will reduce demand for accessible materials while also assisting in the resolution of many disposal issues.
