Reinforcement of Soil Strength by Adding Polypropylene Fibres and RecycledWaste Tire Cords

Soil stabilization is the alteration of one or more soil properties, by mechanical or chemical means, to create an improved soil material possessing the desired engineering properties. Thus, fibre-reinforced soils have recently attracted increasing attention in geotechnical engineering. So, this paper is going to introduce and investigate a novel method for the reinforcement of soil samples. In this way, the composite soils were prepared through the addition of fibres by the injection of lime-water. Polypropylene Fibres (PP) and Recycled Waste Tire Cords (RWTC), an environmental problem, were selected. Consequently, the unconfined compressive test was employed to investigate the compressive behaviour and ultimate-compressive strength of different reinforced-soil samples. So, the effects of lime-water, fibre content, fibre length and fibre type were evaluated
