This present work presents the results of the study of the main properties; the compressive strength and the flexural strength of the fiber reinforced concrete and the relationship between them. Taking into account that the rupture modulus (flexural strength) of hydraulic concrete is crucial for the design of pavement slabs. Said module is theoretically obtained by means of the product of a ratio factor “R“ and the square root of the compressive strength of the hydraulic concrete. In order to determine this relationship between the two behaviors, the experience of the American Concrete Institute (ACI) Committee 363, which establishes a range of variation that is usually between 1.99 and 3.18. With this objective the research focused on the identification of this value of relation “R“ for a concrete reinforced with polypropylene fibers type fibromac 12 and metallic fibers by means of the analysis of test pieces worked in the field. The design of mixtures for a specified compressive strength of 300 kg / cm2 and a flexural strength MR = 42.15 kg / cm2 was started by sampling the latter, compression and flexion tests were performed at 3, 7 and 28 days, with these data it was identified that the quality of the mixtures made is high. The values obtained in the molded specimens reflect an increase in the mechanical properties of the concrete with fibers, also concluding that the relationship between the resistances R = MR/v f´c increased to R = 3.23 with respect to those proposed by ACI 363 and this allows the optimization of our design of reinforced slabs for rigid pavements.
