Effect of Geogrid Reinforcement and Air Entraining Admixture on Behaviour of Airport Concrete Pavement

Cem Alper Caliskan

Abstract: This study evaluates the potential of geogrids as reinforcement materials in airport concrete pavements to enhance tensile strength and ductility. The experimental investigation involved 10 geogrid-reinforced concrete beams tested for flexural behavior using a four-point bending test. Polyester-based (PET) geogrids demonstrated superior ductility compared to basalt-based alternatives. Results indicated that geogrids enhance crack control, with polyester-based geogrids showing better post-cracking behavior.
