Abstract :

Most State highways in the central part of India (e.g., Maharashtra State) have problems of foundation due to presence of highly compressible clayey soils (mostly black cotton soil). The sub grade soil and its properties are important in the design of pavement structure. It has been the common observation and experience that the pavements of highways and roadways constructed either on in situ soil formations or on compacted black cotton soil embankment show several types of damages to pavement structures, and in many instances the pavements may even become unserviceable because of highly deteriorated conditions of the whole pavement system. The present work is aimed to assess the improvement in the strength and stability characteristics in soft Subgrade soil by using the fly ash for the stabilization and then Nylon fibre as reinforcing material. Randomly distributed fibre reinforced soil (RDFRS) technique is used to prepare the reinforced soil samples. In RDFRS technique the mixing of reinforcement in the soil is very easy and no special skill is required. The reinforcement is added by percentage of the weight of the soil sample and by following certain aspect ratio i.e., length/diameter (L/D) ratio. Attempt is made to determine optimum combination of fly ash and fiber content for maximum gain in strength.
