The current study aims to reduce industrial waste disposal by examining the mechanical properties of crumb rubber in pavement layers. The study evaluated the effects of crumb rubber in the concrete mix related to compressive, flexural, and tensile strength. Further, the study also focuses on microstructure analysis with the help of a scanning electron microscope (SEM) test. The load-transfer efficiency of crumb rubber concrete leads to higher resistance against cracks developed in pavement structures. Further, it revealed that crumb rubber concrete provided better fatigue performance while decreasing the crack tendency. The study indicated that the concrete mixed with 10% crumb rubber (CR) partially replaced coarse aggregate yielded good strength. Further, adding 2% basalt fiber and steel fiber enhances the flexural and tensile strengths, respectively. The study concluded that using crumb rubber concrete in pavement structures gives better solutions for sustainable materials and efficient use of waste management.

摘要

The current study aims to reduce industrial waste disposal by examining the mechanical properties of crumb rubber in pavement layers. The study evaluated the effects of crumb rubber in the concrete mix related to compressive, flexural, and tensile strength. Further, the study also focuses on microstructure analysis with the help of a scanning electron microscope (SEM) test. The load-transfer efficiency of crumb rubber concrete leads to higher resistance against cracks developed in pavement structures. Further, it revealed that crumb rubber concrete provided better fatigue performance while decreasing the crack tendency. The study indicated that the concrete mixed with 10% crumb rubber (CR) partially replaced coarse aggregate yielded good strength. Further, adding 2% basalt fiber and steel fiber enhances the flexural and tensile strengths, respectively. The study concluded that using crumb rubber concrete in pavement structures gives better solutions for sustainable materials and efficient use of waste management.
