INFLUENCE OF COMPACTION ENERGY ON SOIL STABILIZED WITH CHEMICAL STABILIZER

Increase in traffic along with heavier magnitude of wheel loads cause rapid deterioration in pavements. There is a need to improve density, strength of soil subgrade and other pavement layers. In this study an attempt is made to improve the properties of locally available loamy soil using twin approaches viz., i) increasing the compaction of soil and ii) treating the soil with chemical stabilizer. Laboratory studies are carried out on both untreated and treated soil samples compacted by different compaction efforts. Studies show that increase in compaction effort results in increase in density of soil. However in soil treated with chemical stabilizer, rate of increase in density is not significant. The soil treated with chemical stabilizer exhibits improvement in both strength and performance properties
