Response of graphene-based geotextiles under hydromechanical loading with sensing applications in smart road infrastructure

Monitoring pavement loading is essential for pavement reliability modelling and maintenance. Current methods have limitations, providing constrained information and incurring substantial costs. This study evaluates a novel graphene-coated conductive geotextile for road infrastructure. Currently used in leak detection, the geotextile is examined for hydro and mechanical loading applications, serving as a pavement sensor. The research addresses deficiencies in current pavement monitoring methods by investigating the electro-mechanical behaviour of the geotextile and its response to moisture. The study also aims to integrate the geotextile into existing pavement monitoring practices through proof-of-concept laboratory experiments.
