Enhancement of Sub Grade Soil Strength using Lime
Keywords:
Black cotton soil, Lime, stabilization, ucsCBRAbstract
Subgrade is an important components in the pavement structure. It takes all the load and transfer it into the ground over a larger area. The performance and durability of pavement also depends on type of subgrade soil and its engineering properties. During construction we come across different types of soil among that Black cotton soil also known as expansive soil is one of the problematic soil. In these unavoidable situation improvement of geo mechanical properties are very much essential. Stabilization is one of the method of ground improvement techniques. It this present study stabilization of black cotton soil has been carries out using lime. The test results has been shown that there is an improvement in strength properties of soil and also decrease in plasticity index .substantial increase in CBR value has been observed.
