In this paper it was analyzed that the mechanical properties, the permeability and the freezing properties of SB-2 materials which are mainly used with the subbase materials. To this ends, a series of the physical test, the permeability test and the freezing test were carried out the samples mixed the small aggregate and the big aggregate from which was re-classified the SB-2. From the test results, it was analyzed the characteristics of permeability and the characteristics of freezing of the samples. And it was reviewed for SB-2 materials that the use of possibility for the freezing prevention layer material.
