Stabilization of Pavement Material: an Economic Solution for Pavements for Better Strength and Cost Aspect

This study throws light on the suitability of waste materials like Brick Kiln Dust, Marble Dust, Marble Chips and Tyre Scraps as soil stabilizer for use in pavement. Also, the suitability of Quarry Dust, which is not considered as a waste material nowadays and 6mm aggregate chips as a soil stabilizing agent is studied. The role of brick kiln dust, marble dust, marble chips, quarry dust, 6mm aggregate chips and tyre scraps in improving the characteristics of expansive subgrade material, capping layer material and other sub base material is analyzed. The amount of cost savings for a pavement when it is stabilized separately with brick kiln dust, marble dust, marble chips and tyre scraps is also studied. The results of the experimental research show that brick kiln dust, marble dust, marble chips, tyre scraps, quarry dust and 6mm aggregate chips can effectively be used as soil stabilizer for subgrade, capping layer and sub base layers as the CBR value is increased.
