Abstract

Black cotton soils or expansive soils which are vastly found in India are known for their susceptibility to varying moisture condition. This causes severe problem for pavement construction in areas where black cotton soils are predominantly present. To cope up with this problem in many sites, soil replacement technique is adapted which is very costly. In present investigation a study area from Samalkot to Uppada in Andhra Pradesh, India is selected having similar problem. Experiments are carried out to stabilize the soil with Vitrified Polish Waste (VPW) as an admixture and geogrid provision. The VPW is mixed in proportions of 5%, 10%, 15%, 20% to virgin soil and the engineering and index properties of soil are evaluated after stabilization. The subgrade soil is also tested for simulated traffic loading condition by providing geogrid membrane in the laboratory and result analysis proved that VPW has a good potential to be used as an additive for black cotton soil stabilization
