In today’s world, the vehicles are increasing day by day and at the same time more amount of tyres are being wasted going to be land filled and burnt creating a lot of environmental foot print. So we have to reduce the wastage to its minimum value. In this context, we got an idea to use the waste rubber which is shredded in soil as a stabilizing material to increase its index as well as engineering properties of soil. We conducted a number of tests to increase the soil strength by adding rubber tyre shreds. The shredded rubber
size considered in our project is which passes through IS 2.36mm sieve. The tests conducted were Grain Sieve Analysis, Atterberg’s limits i.e., Plastic Limit, Liquid Limit, Standard Proctor Compaction Test and CBR test. The shredded tyre is mixed with various proportions in the soil to increase its CBR value by determining its optimum moisture content.
