Abstract

Several parts of India have inadequate bearing capacity and may not support the weight of the superstructure by the weak soil alone. Soil reinforcing techniques can be used for in-situ soils as a viable building material for a variety of projects with reinforcing materials like geogrid, geocell, confinement, etc and these are extremely expensive. In order to reduce the cost of construction, alternate and local available waste materials are needed as sustainability is the key. The increasing use of plastic goods has led to new issues with waste management; hence these waste items can be used to enhance the geotechnical qualities of the soil to increase the soil's bearing capacity, which avoid disposal issues. In this study series of model tests are conducted with plastic bottles as reinforcement, using sand at varying densities, reinforcement layers and the distance between the base of footing to first reinforcement layer. It is observed that the parameter selected in the present study has increased the load carrying capacity up to 262.5% compared with unreinforced soil.
