The soil reinforcement is a method to improve the soil properties using the proper additives. An example of such additives is synthetic fibers, which improve the strength parameters of the soil. In this paper, the effect of the polypropylene (PP) and the glass (GS) fibers on the strength of the clayey sand (SC) soil stabilized with different contents (0.2, 0.5, 1, and 1.5%), using the unconfined compressive strength (UCS) test, has been studied. The results showed that by increasing the fiber content for both types of fibers, the values of UCS are considerably enhanced, and for 1.5% fiber content, they all reach their maximum values. In addition, PP fibers have shown to be more effective in enhancing the UCS, elastic modulus (E), and ductility compared to the GS fibers. This can be attributed to the fact that PP fiber has higher tensile and flexural strength compared to GS fiber. [ABSTRACT FROM AUTHOR] |
