Abstract

Construction of a large number of roads in India under various projects requires good quality aggregate. The scarcity, high cost and extraction of these aggregates has led to the investigation of cheaper materials of sufficient strength for the construction of roads. The marginal materials or the locally available materials are thus employed to serve the purpose. The use of the marginal materials having comparatively less strength will affect design, construction and pavement performance. These materials may often cause poor performance thus leading to rutting, shoving, cracking, aggregate abrasion, raveling, low strength, low skid resistance, shortened service life etc. In order to utilize these materials effectively certain modifications or improvement is required which is achieved by stabilizing these materials using various stabilizing agents. Stabilization is a process of improving the properties of the marginal materials to get desired engineering properties. The paper highlights various stabilizing agents such as coarse grained materials as well as lime, cement, fly ash and also mixture of these to stabilize weaker soils/marginal materials. Various tests required to test the suitability of these stabilized materials has also been discussed. Also the issues associated with the use of these stabilizing agents and their possible solutions have been discussed.
