## Abstract
This study is intended to increase the compressive strength and durability of subgrade with lime, on high plasticity expansive soil. The composition of the stabilizing agent used; composition-1 is soil + 5% slakelime, composition-2 is soil + 5% quicklime, and composition-3 is soil + 5% (quicklime with rosin and iron oxide activation). The testing includes swelling test, durability test, and CBR test. That the performance of stabilization with the composition-3 was able to reduce the swelling potential on 3 th day by 93.89%, decrease the volume increase potential by 93.09% and decrease the weight increase potential by 94.00% in the 3 periods of wet-dry cycle, and increase the CBR value by 758.62%. That the activation of gum rosin and iron oxide on quicklime can significantly improve the performance of lime for stabilization of expansive clay as subgrade of highway.
