Abstract: The biggest challenge for developing countries like India is to build a complete network of road systems and provide a limited source of funding. The use of local materials can greatly reduce construction costs. If the stability of the local soil is insufficient to support the wheel load, the performance is improved by soil stabilization techniques; for example, the use of geogrids to use randomly distributed fibers or waste plastics in the subgrade soil, which helps to increase the strength of the roadbed. Research has been carried out in this field to improve the engineering properties of subgrade soils by adding different types of waste plastics. In this study, different types of waste plastics were randomly mixed with soil and then subjected to a series of California Bearing Ratio (CBR) tests to assess the strength of the subgrade soil. Various percentages of high density polyethylene (HDPE), low density polyethylene (LDPE) and polypropylene (PP) are used to improve soil strength. The results of the CBR test indicate that the addition of these materials to the subgrade soil provides effective strength for the subgrade soil. It was observed that the CBR value increased to a certain percentage as the fiber content increased, but decreased as the waste plastic content was further added. The pavement section adopts modified subgrade design, using HDPE, LDPE and PP, and analyzes the critical strain value of the top of the subgrade and the bottom of the asphalt layer, and compares it with the allowable value of IRC: 37-2012 The traffic load of the four-lane regional road project is 150 MSA. The reduction in crustal thickness and project cost savings were compared by different waste plastics and different plastic content.
Keywords: Highway, Waste Plastic, High density polyethylene (HDPE), Low density polyethylene (LDPE), Polypropylene, CBR.
