Experimental Study about Soil Improvement with Glass Fibers

Abstract

Soil stabilization methods are important in dealing with for geotechnical engineering and transportation engineering departments. In addition to that, soil stabilization is becoming an alternative for increasing the strength properties of cohesive soils. There are a lot of stabilization methods and one of the most important stabilization methods is the soil stabilization with glass fibers. In this study, serious tests have been applied in the laboratory to investigate the availability of soils with glass fiber for increasing the bearing capacity and decreasing consolidation settling. For this purpose, the cohesive soil were prepared adding 0%, 5%, 10%, 12%, 15%, 17% and 20% with glass fiber for determining effect of glass fiber strength at cohesive soil's road subgrade. According to results, all combinatons of glass fibers showed higher improvement engineering properties of soil. In according to that, this study indicates mixture containing 17% rubber particles is the best suitable solution in the stabilization of cohesive soils.
