Abstract
In the present paper, the effect of alccofine and tyre buffings addition on the compression and bearing ratio of sand are evaluated through laboratory study. On the basis of compaction test, a reference mix composed of sand + 12 % alccofine + 2 % tire buffing was selected for further study. The unconfined compression and bearing ratio test on the reference mix was then carried out by curing the sample for 7, 14 and 28 days respectively. The compression strength and penetration resistance of the reference mix were found to increase substantially with increase in curing period. The obtained compression strength and bearing ratio of the reference mix suggests that the reference mix can be effectively used for pavement application and further will help in utilizing the waste quantity of tire buffings.
