Due to montmorillonite black cotton soil is an expansive soil which years ago. However, their major weakness is that they has undesirable plasticity characteristics it possesses high severely pollute the environment: littering parks and swelling and shrinkage properties and high optimum moisture roadsides, clogging sewers and filling landfills. With content. The swelling and shrinking process of a sub grade landfills rapidly filling up, finding a solution to this black cotton soil results into failure of structures in the form of non-degradable polyethylene waste is key to a settlement and cracking. It may cause damage to the structure sustainable environment. This research, therefore, was constructed on black cotton soil. Therefore, prior to undertaken to investigate the potential increase in soil construction of structures like foundation, buildings, shearing strength when it is reinforced with plastic pavements, roads on such subgrade, it is important to improve strips. It was anticipated that positive laboratory the engineering properties of soil by stabilization. Plastic bags results could trigger field applications, success of of general use are produced from non-renewable petroleum and natural gas resources. Plastic bags are nonwhich would permit reduction of the plastic grocery biodegradable. India and all over the world, facing the bag wastes destined to landfills bringing along problem of disposal of plastic waste. In present project environmental and economic benefits. utilization of polyethylene shopping bags waste used for improvement of soil properties. The plastic strip of lengths 20mm,40mm,60mm and width 10mm and 15mm are mixed with the black cotton soil by 0.15%,0.30%,0.45% and 0.60% by the weight of soil and standard proctor, UCS and CBR tests are conducted on mix the results obtained form the tests are shown that mixing of this material in black cotton soils is effective for improvement of soil properties.
2. MATERIALS AND METHODS 2.1 Soil Material Black cotton clayey soil was used in this study collected from Ganur Tal. Chandwad Dist- Nashik, Maharashtra, India. The collected soil is low plastic silt (ML). Then the soil was screened through the sieve of 4.75 mm aperture before preparing the specimen for testing. According to the Unified Soil Classification Systems soil is clay.
Key Words: Polyethylene Plastic bags, Soil reinforcement, Ground improvement, Waste.
1.INTRODUCTION A large part of Maharashtra are covered with black cotton soils. Black cotton soil is an expansive soil which is having undesirable plasticity . Black cotton soil contains the clay mineral montmorillonite. Montmorillonite is unstable clay mineral, thus the soil have high swelling and shrinkage characteristics. It is very difficult to construct a structure with this soil, as black cotton soil has very low bearing capacity and it do not possesses sufficient strength to support the loads imposed upon them during the service life of the structure. For building a structure on such soils, the ground properties of such soil need to be improved. The study area in the present work consist of black cotton soil, So the main objective is to stabilize the soil and improve its geotechnical properties in order to make use of the soil in the study area for construction purpose. © 2017, IRJET
