The soil improvement methods recently became an attractive topic for geotechnical engineers. Because theydo not have any control over the process of soil and some soil mass may not be suitable for supporting the desiredfacilities. When the mechanical qualities of these soils are lower than those required, stabilization can be an option toimprove performance, notably in enhancing its strength. The solid waste materials are preferred as additive materials insoil improvement processes because they are more economical than factory product additive materials. As a result,researches in this direction show an increase. One of the solid waste materials is plastic bottles and produced using thePolyethylene Terephthalate. This study reports the properties of sandy soils when waste of the plastic bottles is used infiber form as additive material in reinforced sandy soils. In this study, straight and irregular recycled polyethylene fiberswere used. The percentages of recycled plastic fibers added in the concrete mix were 0.1%, 0.2%, and 0.3% respectively.The strength values show that the stabilized sandy soil samples with the waste of the plastic bottle fibers have highstrength when compare with the unstabilized sandy soil samples. The results show that the reinforced sandy soil sampleswith the waste of the plastic bottle fibers have high strength when compare with the unreinforced sandy soil samples.Consequently, it is concluded that the waste of the plastic bottles materials can be successfully used for the reinforce ofsandy soils in the geotechnical applications.
