In late years, it may use in combination deep mixing method and shallow mixing method for the purpose of cost reduction in the soft ground measures of road embankment. When we thin thickness of shallow improvement layer and combine it with the deep mixing column of the low improved rate, tensile stress occurs in a base of shallow improvement layer. The specimen and the adhesion method with the testing equipment become important to perform a tension test of the improved soil. In addition, it is important to make a homogeneous specimen so that local weak parts do not affect the test results. Therefore, three types of soil were used to make an improved soil, and unconfined compression test and unconfined tensile test were performed. We mixed solidification materials to three kinds of ground materials and made solidification materials improvement soil and carried out one axis compression examination and one axis tension test. In this report, In this report, we report the result of examining the method of compacting the specimen to the soil improved by solidifying material and the method of preparing the mixed sample to make a homogeneous specimen.
