Abstract: Problematic Soil improves by better root growth, water movement, and also by mixing portions of the soil profile, to provide more uniform texture. As a ground improvement technique to improve the strength of problematic soils and this study is carried out to understand the settlement behaviour of layered soils. The soil which is collected was found to be problematic in nature, which is more swelling in nature. The samples of soil are collected the from Mudichur road, Tambaram. The sand used in this study is taken from nearby site and is used to improve the problematic soil by forming a layer of required thickness. The preliminary tests are conducted on the soil samples to determine their properties as per IS standards. After the preliminary test, the plate load tests are performed on the soil with square plate (10 mm x 10mm) in order to know the bearing capacity of soil. The load tests are performed on sand and clay layers with varying thickness of 5cm, 10 cm and 15 cm of sand over clay soil. From the plate load test the load- settlement behaviour of soil layers are studied. It can be conclude that if different layers of sands are provided over Problematic soil then It gets enough Load bearing resistance which can be further gets implemented during Highways constructions. The results says that of 15 cm layer of sand shows maximum load bearing capacity & shown better load – settlement graphs as well.
