This study investigates the application of Geosynthetic Cementitious Composite Mats (GCCMs), specifically Concrete Canvas (CC), to reinforce railway substructures. Combining waterproofing, durability, and ease of installation, CC addresses challenges in ballasted railway tracks, such as local failures, moisture, and dynamic forces. The research fills a gap in the literature on CC's dynamic performance and its comparison to geogrids. Experimental methods, including shear box and static plate load tests, revealed that CC increases load-bearing capacity by up to 72% and improves shear resistance through its semi-rigid interlocking mechanism. Robust under dynamic forces, CC ensures stability without deformation. Compared to geogrids, CC offers similar reinforcement, with added benefits like easier hydration and installation. The study concludes that CC is a cost-effective solution for reinforcing railway substructures and improving load distribution and stability. Future research should address environmental impact and integration with advanced materials for enhanced performance and sustainability.
