Soil reinforcement is one of the most popular ground improvement techniques. Availability of different material and techniques for reinforcement is one of the major reasons for the continuous increase in the application of the soil reinforcement. Rapid industrialization is full filling the need of the present time and it is also producing a huge amount of waste Under the present investigation, a detailed parametric study through a series of triaxial experiments has been carried out to develop an understanding of the behavior of geocell-shredded tyres reinforced sand under triaxial loading. The influence of various parameters pertaining to geocell- shredded tyres reinforced soil such as relative densities (i.e., 30%, 50%, 70%), confining pressures (i.e., 50kPa, 100kPa, 200kPa), types of geocells (i.e., M=4.79, 3.23), and shredded tyres content (i.e., 10%, 20%, 30%, 40%) have been studied extensively in a systematic manner. The results of the triaxial tests show that the stiffness and the load carrying capacity of the soil improve substantially with the provision of shredded tyres reinforcement in content 10% and 20% respectively while results of tyre content 30% and 40% show less stiffness and the load carrying capacity of the soil. The stiffness and load carrying capacity of the soil also improves with the provision of reinforcement of soil using geocells and also improves with the provision of reinforcement of soil using geocell-shredded tyres. When geocells are used with shredded tyres for reinforcement of soil then improved results have been seen in 10%, 20%, and 30% tyre content as compare to geocell reinforcement of soil without shredded tyres. While 40% of tyre content shows less load carrying capacity as compare to lesser contents of shredded tyres.
