Effects of waste tire textile fibres on geotechnical properties of compacted lime-stabilized low plastic clays
In this research, concurrent employment of Waste Tire Textile Fibres (WTTFs) and lime in two types of low plastic clays (soil A and soil B) is investigated by performing various tests, namely, standard Proctor compaction, Direct Shear, UCS, CBR and Split Tensile Strength (STS). Fibre inclusion with an optimum weight content of 1.5% led to an improvement in strength parameters of soils. Cohesion and internal friction angle were enhanced as a result of lime-stabilization. Simultaneous employment of 1.5% of fibres and 6% of lime increased the UCS by 10.66 and 7.95 times in the examined clays. It was demonstrated that fibres compensated for the brittleness induced in the soil by lime admixture. Therefore, concurrent addition of lime and fibres produced excellent specimens in terms of both strength and ductility. Soil mixtures with an optimum fibre content of 1.5% increased the CBR value of soils A and B by 4.9% and 3%, respectively. Moreover, the concurrent addition of 1.5% fibres and 4% and more lime increased the CBR value by more than 100%. STS was also enhanced by fibres and lime addition. Concurrent reinforcement by 1.5% of fibres and stabilization by 6% of lime in soils A and B increased STS by 23.6 and 14.5 times, respectively.
