Abstract


Sand loamy soil is often used as construction material for buildings and highways. The disadvantages of this soil are low density and high permeability that can reduce the quality ofroad construction. One way to improve the
quality of the soil is to stabilize it with cement added material. This study aims to determine how much the velocity of permeability of subgrade and to the addition of the Portland Cement Composite (PCC) mixture with variations
of 2%, 4%, and 6%. Calculation analysis method uses SNI M.22-1990-F. From the permeability test with the variation of native soil without cement mixture, the coefficient value is 10.025 cm/hour, with the addition of 2% cement the coefficient value is 7, 132 cm / hour, the addition of 4% cement is obtained coefficient of 6.245 cm /hour, the addition of 6% a value of 5.208 cm / hour was obtained. So it can be concluded that along with the increase in cement content for the clay sand mixture, the coefficient value is getting smaller
