Assessment the Role of Recycled Bottle Fragments and Littered Rubber Fibers on the Sandy Soil Engineering Behaviors

Rusted bottles and ragged car tires are good examples of modern waste materials, which can cause significant environmental concerns. Despite all environmental issues of these materials they could be used as a reinforcement material in weak soils. This strategy not only reduces the volume of waste materials but also can make them valuable. The results of laboratory tests have shown that using PET crushed particles can improve the engineering properties of sandy soils while for rubber fibers these changes are not as positive as PET particles. In fact using rubber fibers has damaged some of the engineering characteristics of the sandy soils.
