Strength Behaviour of Expansive Subgrade Soil Stabilized with Coronus Material

Abstract Expansive subgrade soil needs to be re-engineered enhance the load-bearing capacity as it lacks sustain traffic and pavement load. Although various chemical modification techniques have proven effective for stabilization, they are expensive unsustainable. Coronus aggregate material is an uplifted coralline deposit abundantly available in Pacific. The current study focuses on strength behavior of fine-grained notably clayey when blended with coronus a potential alternative usual stabilization methods employed construction industry. To successfully stabilize sample material, particle size distribution, coefficient uniformity, curvature were determined. results indicate that well-graded. consistency was determined using four-point Casagrande method Atterberg limits i.e, liquid limit, plastic shrinkage limit soil. stabilized standard compaction tests calculate maximum dry density optimum moisture content clay before after blending 10% increments material. California Bearing Ratio (CBR) test all samples CBR laboratory tests. It has been observed addition improved Hence, recommended that, wherever possible, utilized stabilizing agent improve geotechnical properties expansive
