Abstract

Land is the place where a structure or construction is established, both construction of buildings and roads. What often causes problems is if the soil has bad properties such as high plasticity and a large potential for shrinkage. One way to improve the shrinkage properties is to stabilize the soil with added cement and fiber to determine the dynamic compressive strength of subgrade in the form of clay and the effect of dynamic compressive strength of clay to the addition of cement and fiber. Clay mixed with cement and fiber was tested by dynamic compressive strength test using the SNI 03-6887-2002 method. The percentage addition of cement, cement and fiber is 5%, 10%, and 15%. Addition of fiber is 1% by weight of the cement used for each variation. The value of the dynamic compressive strength of the subgrade is 1,080 kg / cm2. The value of dynamic compressive strength of clay stabilized with cement was 4.45 kg/cm2, 7.77 kg/cm2, 9.35 kg/cm2. Cement and fiber are 3.86 kg/cm2, 6.06 kg/cm2 and 10.08 kg/cm2. Soil mixed with cement is strong but brittle, with the addition of fiber, it can change the pattern of collapse that occurs, which is from patterns that behave in a brittle manner to patterns that behave in a ductile manner.
