Soil is an important element that can not be separated in a construction project. Therefore, the soil should have good carrying capacity so that it can carry the load above it perfectly. But, usually soil with poor bearing capacity is not uncommon to fine. One of those is expansive clay soil which has high shrinkage and swelling properties as to endanger the structure above it. One effort that can be done to solve the problem is by stabilization. Stabilization aims to reverse the decline, increasing the shear strength which means to increase the carrying capacity of the soil (Das, 2007). Many methods of stabilization that can be done such as by mixing chemicals.In this research, stabilization by mixing the soil using two types of Chemicals admixture, those are gypsum with a variation of 5%, 10%, and 15% and Soil binder with a concentration of 20 gr / lt of water, 25 gr / lt of water, and 30 gr / lt of water aimed to determine the effect on the soil plasticity index values and comparing the value of shear strength parameters of the mixture with the original soil conditions using a Triaxial UU test.Based on research done shows that with increasing variations in the mix, then the value of plasticity index decreased which was originally 42% (very high degree of swelling) becomes worth 11.24% (lower Swelling degree) when a mixture of gypsum 15% and 30 gr / lt water soil binder. As for the value shear strength parameters increased in all variations of mixture. Admixture with the highest shear strength parameters value is at 15% the mixture of gypsum and 20 gr / liter of water of soil binder with 14 days treatment period which has enhanced the cohession value of 559.01%, the friction angle by 1157.14%. and a shear strength value of 568.49%. It can be concluded that the admixture of gypsum and soil binder correctly can increase the value of shear strength parameters significantly and decrease the value of plasticity index of the soil.
