Summary:In this study, sustainable polyurethane-based polymer rubber concrete (PU-based PRC) was prepared using crumb rubber (CR) and ground glass fiber (GGF) particles for road pavement and runway repair. Moreover, tensile characteristics and failure mode of rigid GGF/PU grout materials were investigated. Response surface methodology/central composite design tool was employed to analyze the responses’ compressive strength, flexural and relative density. CR and GGF particles were used as input variables. The result indicates that the combined effect of CR and GGF particles improved the mechanical properties of PU-based PRC specimens, and a reduction in mechanical properties was observed in samples blended with high CR content as only admixture material. On the other hand, the tensile characteristic of GGF/PUgrout material decreases with an increase in GGF content. The developed models have successfully predicted the mechanical behavior and relative density of PU-based PRC using CR and GGF particles as the independent variable with high accuracy. The optimized PU-based PRC mix could be achieved by partially replacing 13.47%CR and the addition of 3%GGF. Moreover, scanning electron microscopy revealed that the reinforcing mechanism of GGF particles had bridged the cracks and voids.
