In Pavement Design and Construction, there is an urgent need of economical and innovative Technology that reduces energy consumption and Green House Gas (GHG) emission apart from providing sufficient strength and durability to pavement. Soil and aggregate Stabilization is one of the solutions for obtaining sustainable pavement and economically mitigating the critical issues such as energy consumption and GHG emissions. Stabilization with RBI Grade 81 is one such solution. It is a natural inorganic material that is used in aggregate and soil as pavement material and soil Stabilizer. Soil or aggregate can be stabilized with RBI grade 81 and then can be used in Subgrade and also as Sub base and base Layers.
This paper presents and analyses various lab test results of RBI Grade 81 with five different type of soils, mixture of Black cotton and stone dust and a mixture of 10mm down Aggregate and stone dust to prove its suitability as a soil Stabilizer and Pavement material in Sub base and Base layers.
