Engineers frequently aim to enhance the road's surface and texture in response to stress-induced reflection and deformation by reinforcing the underlying concrete structure of the pavement. Studies have shown that the utilization of crushed concrete and steel fiber reinforced concrete (SFRC) can enhance the performance and cost-efficiency of concrete. This study investigated the advancement of a durable concrete road surface capable of withstanding heavy vehicular loads. The experimental laboratory program consisted of four groups: standard concrete, concrete with crushed concrete, steel fiber reinforced concrete (SFRC), and a mixture of crushed concrete and SFRC. The simulation testing process involves two steps: first, separating a validation sample from a previous study, and second, widening the inquiry to analyze the impacts of different concrete pavement thicknesses and dimensions. Studies have demonstrated that the addition of crushed concrete at a rate of 10-20% and steel fiber reinforced concrete (SFRC) at a rate of 40% may significantly enhance the performance of concrete with a compressive strength (fc) of 30 MPa. The results indicated that crushed concrete exhibited significantly higher shear strength compared to SFRC and ordinary concrete. In addition to the enhancement in shear strength, the overall performance of the concrete material was also improved. Ultimately, the incorporation of crushed concrete and Steel Fiber Reinforced Concrete (SFRC) is accountable for the enhanced mechanical properties of concrete in all concrete pavements.
