Road construction is an activity in which natural resources are utilized. Large quantities of natural materials like gravel, rock, and sand are used in kilometers of newly-laid roads. At the same time, the sustainable development concept requires more efficient management of waste materials, preservation of environment and cost. In the present scenario, the safe disposal of different wastes produced from industries causes several problems. Several million metric tons of wastes are produced in these establishments. The utilization of these materials in road making is based on technical, economic and ecological criteria.
The lack of traditional materials used for making roads in protecting the environment makes it imperative to investigate the possible and careful use of these materials. Traditionally, soil, stone aggregate, sand, and others are used for road laying. Natural materials being exhaustible, its quantity is declining gradually. Also, the cost of extracting good quality of natural material is increasing. If these materials can be suitably utilized in highway development as stabilization material in the subgrade, the pollution and disposal problem is partly reduced. In the absence of other outlets, these solids waste have occupied several acres of cultivable lands throughout the country. Considering these aspects, the need for bulk use of solid waste in India, it was thought convenient to test this material, develop specifications and enhance their use in road making to obtain a high rate of returns. Material such as copper slag from copper extracting industries, steel slag from steel extracting companies, fly ash and other solid wastes have already proved to be useful for road laying in many other countries. California Bearing Ratio (CBR) tests are conducted to check the effect of adding waste materials in determining the strength and performance of the soil and the results are compared with that of test results made with natural soil.
Why: Problem statement
The structural foundations and roads constructed on soil may undergo differential settlement.
How: Solution description
The project provides how to improve various engineering properties like compaction, strength and bearing capacity of the subgrade with the addition of copper slag to the natural soil below the bitumen paving. The technology of adding copper slag wastes in soil stabilization leads to proper utilization of this waste and also solves the problem of mass disposal. In this investigation, the soil is partially replaced with copper slag at different percentages and the optimum percentage of copper slag is determined from conducting tests like Specific gravity, Proctor compaction, and CBR.
How is it different from competition
The replacement of industrial waste materials as earth reinforcement in road construction by the combination of soil and copper slag resulted in higher strength when compared to the natural soil. From the overall analysis of the test results, it was observed that the optimum percentage of copper slag required to strengthen the poor subgrade of soil was 60% (Category-D).
