Some soils due to undesirable technical specifications and having substantial amounts of clay or silt, for road construction operations are inferior. In cases where the soil is undesirable technical specifications to promote technical parameters and in cases where soil replacement is not economical, soil improvement must be investigated so that if it is technically and economically justifiable proceed to do it. Soil stabilization is improvement of physical and engineering properties of soil to provide a series of predetermined objectives that one of the proper strategies for the operation and faster implementation of projects. In this project, for soil stabilization used from waste cellulosic fibers mixed with polyvinyl alcohol resin. This mixture of fibers and resins are commonly found in loom factories and workshops for waste. Laboratory variables in this project is the percentage of fiber and processing period and CBR and compression tests were conducted in both dry and saturated conditions. By doing the compression test on sand without additives and sand with 0.5% and 1% of cellulosic fibers mixed with polyvinyl alcohol resin it was found that optimum moisture content has been reduced to the amount of 1%. As a result, the optimum moisture content for CBR tests obtained for sand without additives, 12% and for sand with additives, 11%, CBR tests done in the dry state with no additives and four different content of fibers (0.125, 0.25, 0.5, 1) and with two different curing period (6 and 24 hours) and it was found that the CBR value had the highest increase by adding 0.25 percent of fibers and 24 hours of curing in comparison to the sand without additives. CBR value increased to 0.25 percent of fibers and decreased with higher percent of fibers. Also, CBR value with curing period of 24 hours is higher than CBR value with 6 hours curing period in al states. CBR tests done in the saturated state with no additives and three different content of fibers (0.25, 0.5, 1) and with 24 hours curing period and it was found that the CBR value had the highest increase by adding 0.5 percent of fibers and 24 hours of curing in comparison to the sand without additives.
