摘要

With rapid urban and industrial developments, large quantities of wastes are being generated worldwide. The disposal of these wastes in landfills is not a sustainable solution for countries like India due to availability of limited land space. Waste management and waste reduction can be achieved through recycling or re-use. Utilization of industrial wastes in geotechnical applications is likely to provide viable, environmentally friendly and sustainable solutions. In view of these requirements, an experimental study was carried out to demonstrate the potential of using two industrial wastes, namely fly ash and waste recycled product (WRP) generated after recycling of blast furnace slag from steel plant, reinforced separately with high density polyethylene (HDPE) plastic waste strips. Three different sizes of waste plastic strips were used in this study. The effect of strip content (0.25% to 4%) and strip length on the California bearing ratio (CBR) and the secant modulus of plastic strip-reinforced fly ash and plastic strip-reinforced WRP were investigated. The study reveals that the addition of waste plastic strips to fly ash and WRP results in appreciable increase in CBR and secant modulus. The proposed materials can be used in flexible pavement construction leading to safe and economical disposal of these materials that otherwise would be disposed as wastes.
