Utilisation of Waste HDPE strips in Expansive Soil and its Behavioural Analysis

Abstract

The road pavement shows often bad after every monsoon and develops cracking, potholes, settlement at various points etc. Especially in Maharashtra state most of the area is occupied by black cotton soil. Its fundamental property is when it is dry carrying a maximum strength, but when hike in moisture content loses its strength gradually. Urbanization and growth in the economy of India have led to steep increase in building construction and infrastructure projects such as Highways, Railways etc. At the same time HDPE pipe is the most abundant of all residues, disposal take more land also non-degradable material. So, disposal of HDPE plastic ecologically in suitable manner has lately become global concern. Demonstrate the potential of reclaimed waste HDPE as soil reinforcement for improving properties of sub grade soil. HDPE strips obtained from waste were randomly mixed with the soil. A series of California Bearing Ratio (CBR) and Unconfined Compression Test were carried out on treated soil by different aspect ratios and percentage of HDPE strips. The feasibility of adding HDPE waste plastic is concluded for improving the engineering properties by Experimentally & Analytically. An eco-friendly technology is present which can benefit the society
