Evaluating the Performance of Sand–Geotextile Biocemented Interfaces
The relative sliding between soil and geotextile in the interface zone leads to the pullout of geotextile reinforcement. The tensile strength of the geotextile limits the sliding resistance offered by the interface bond resistance. The biotreatment of soil-geotextile assembly is a sustainable and ecofriendly method to improve the interface. The biocementation options are possible in soil, geotextile individually, and as a unit. The interfacial interaction of five different interface combinations were analyzed by performing interface tests and microstructural analysis. The maximum improvement in adhesion was observed in the biocemented sand geotextile system. The maximum (interface) frictional resistance was observed in interfaces of biotreated geotextile with or without biocementation for sand, attaining peak interface friction angles of 41° and 38°, respectively. The comparisons of interface strength, resources consumed, reaction time, and feasibility are presented in the study alongside the application options. The study facilitates adopting and optimizing the interface for targeted large-scale applications.
