Abstract: The study was aimed to find the effect of lime on Atterberg limits of soil. The experiment was carried out using clay as soil sample and tests were conducted on various proportions of lime ( i.e 2%,4%,6% of lime in addition by weight of soil sample). The experiment shows the increment in liquid limit and plastic limit of soil on addition of lime upto 6%. The experiment also shows the declination in plasticity index on increasing the proportion of lime.
