N2 - Conventional reinforced concrete is widely used in the pavement construction despite its technical drawbacks, economic and environmental issues. To address these matters, the concept of functionally graded material (FGM) with materials that present changeable properties over its volume is adopted on concrete, generating functionally graded concrete (FGC). However, more studies are needed to understand how this material performs. In this study, six mixes of FGC concretes were produced to assess the effect of the recycled aggregate and different depths of the fiber reinforced layer on the flexural performance. Besides, the inductive method was performed to estimate the fiber content and distribution in the mixes. The outcomes of the study highlight the inductive method as a good tool to perform the quality control of the mixes and that FGC produced with recycled aggregates and fibers present great potential in terms of Serviceability Limit States (small deflection).
