The life of flexible pavement depends on properties of the subgrade soil and traffic volume density. Clayey soils are considered to be problematic due to its swelling and shrinkage characteristics. To overcome this problem it is necessary to stabilise the clayey soil. The present study deals with stabilisation of subgrade soil by using stone dust and RBI Grade 81 as additives. The RBI Grade 81 ...
