STUDY ON LATERITIC SOIL TREATED WITH A CEMENTITIOUS STABILIZER FOR USE AS PAVEMENT MATERIAL

Abstract

Road network in rural areas plays an important role in development of agricultural base country, like India. The life and maintenance of rural road depends on strength of subgrade soil and traffic intensity. Options for dealing with poor soils include attempting to dry and compact the subgrade; reinforcing the subgrade with a geo-synthetic material; applying a chemical stabilizer such as lime, cement, polymer or other amendment and/or designing a very thick and expensive pavement section. Traditional lime and cement treatment can be very effective, but the use of lime and cement are limited due to issues with dust control and other handling problems.
