Abstract
In this study, an alternative and environmentally
friendly method for the reinforcement of dune sand is
proposed. This technique consists of using randomly distributed
rubber fibers to improve the engineering properties
of sand. Rubber fibers are added to the sand with different
percentages: 0.25, 0.5, 0.75, 1, 1.25, 1.5, 1.75 and 2% of
dry weight of sand. The experimental program carried out
consists of investigating the effect of rubber fibers on the
shear strength properties of sand. Reinforced and unreinforced
samples are tested in the dense as well as loose state.
The results obtained showed that the inclusion of rubber
fibers in dune sand will improve the engineering properties
of various civil engineering applications such as shallow
foundations and slope. Therefore, incorporation of rubber
fibers can enhance the shear strength characteristics, peak
and residual strengths, and introduce more ductility to the
mechanical behavior of sand. In addition to the technical
effect, this paper emphasizes another environmentally
attractive option, which is the use of rubber fibers as
reinforcements for granular soils as this helps to remove
some parts of these wastes and protect the environment.
