Abstract
The process of soil stabilization refers to changing the physical properties of soil in order to improve its strength, durability, or other qualities. Typically, this is important for road construction, and other concerns related to the building and maintenance of infrastructure. Soil that has been stabilized will have a vastly improved bearing capacity, and will also be significantly more resistant to being damaged by water, frost, or inclement conditions soil). This research briefly describes the suitability of the gypsum to be used in the stabilized soil. Unconfined compressive strength (UCS) used as indicator to the strength development and hence evaluating the performance of gypsum stabilized soil. This research focusing on the effect of gypsum as a soil stabilizer. A various mix design at different percentage of gypsum (0, 4%, 8%, 10% and 15%) were prepared and cured for 0, 7, 14 21 and 28 days. Then the unconfined compressive strength (UCS) was carried out on 38mm diameter x 76mm height specimens. The lowest unconfined compressive strength test results were found in the gypsum content of 0% and curing for 0 days of 3.8667 kg / cm2. While, the largest found in the gypsum content of 8% with 28 days of 14.2 kg / cm2. Curing increases the strength of soil. The addition of gypsum is effective for stabilization of clay soil.
