Increase of Sandy Soil's Soil Bearing Capacity Using Plastic and Bitumen

Abstract

In order to improve the soil's engineering quality, soil stabilization can be defined as the changing of soil parameters by chemical or physical methods. Increases in the soil's carrying capacity, resistance to weathering, and permeability are the basic goals of soil stabilization. This may be accomplished through the use of controlled compaction or the use of suitable admixtures such as cement, lime, and waste products such as fly ash, phosphor gypsum, etc. This innovative method of soil stabilization can be utilized to tackle societal challenges, reduce waste production, and create useful resources from non-useful waste. Waste plastic bags have been used in bituminous mixtures, and it has been demonstrated that they improve the mixture's characteristics. This plastic-coated gravel is combined with hot bitumen to create a mixture that is used to build roads. Bottles and other plastic debris are combined with bitumen to improve the engineering performance of subgrade soil and to achieve the greatest dry density, CBR, and UCS investigations. Bitumen and plastic garbage were thrown onto the earth at random. On randomly reinforced soil with changing percentages of plastic waste and bitumen in various sizes and quantities, a series of Standard Proctor tests, California Bearing Ratio (CBR) tests, and Unconfined compression tests were conducted.
