Construction on clayshale susceptible to durability problems due to that soil very easily weathered when in contact with water and air. Clayshale durability may decrease when subjected to drying and wetting cycles. The aims of the study are to analyze cement stabilized clayshale durability affected by the shape of the sample and mixing method. The cement content that used was 10 percent by weight of the dry soil and prepared using dry mix method and spray mix method. There are two kinds of mold that used to prepared specimens i.e. mold A and mold B. Mold A measures 3,5 cm in diameter and 7 cm in high, the specimens are prepared as high as half a mold. Mold B is 7 cm in diameter and 14 cm high, specimens are molded and divided into fragments weighing 40-60 g. The result of this study indicates that adding cement can increase the stability of soil and reduce the degradation of soil. Specimen B and dry mix method have greater durability than specimen A and spray mixing method.
