The overall performance of a flexible pavement structure underneath loading circumstance is ruled by the properties of materials used in base and sub base layer. The highway construction industry has made rapid studies in the field of new technology up gradation and adoption with increase in traffic volume and increase in demand for innovative design, repair& Rehabilitation of the available transportation infrastructure. New materials and strategies have been attempted with lot of emphasis on optimizing existence cycle cost and minimizing layout price. RBI Grade 81 is an odourless beige powder this is composed of a number of naturally going on compounds. It improves the structural residences of soil. It works by means of hydration reaction. Through the addition of low dosages of RBI Grade 81 the strength of the soil is increased notably. The response of RBI Grade 81 with granular particles produces an inter particle blend that binds the particles together right into a inflexible mass. This binding of the particle, thru both chemical bonds and fractional forces, serves to restrict the pore quantity of the created inflexible stabilized base layer. In this study, an attempt is made to have a look at the effect of overall performance enhancers utilized in base layer. In addition to the laboratory experimental work, evaluation of results when the material is applied in field has also been studied. The California Bearing Ratio, Maximum Dry Density, Degree of compaction were determined for the samples collected from Ammapet Village, Erode district., Tamilnaduat different chainages and these results are compared with the design data. Economic analysis was performed for unmodified soil and soil modified with RBI Grade 81 and theresults were compared.
