In the current research, a study of the mechanical properties of the concrete used for the rehabilitation of flexible pavements was carried out, through the Whitetopping methodology, by means of the addition of synthetic fibers. This new technique was applied in the Central Avenue of San Juan de Lurigancho, in Lima, for which the general objective was to determine the change in the mechanical properties of concrete with the addition of the aforementioned synthetic fibers to rehabilitate flexible pavements. The results were satisfactory, obtaining for the tensile strengths an increase of 27.30 kg/cm2 without fiber to 33.80 kg/cm2 with 4% fiber, and 41.71 kg/cm2 with 7% fiber. Regarding flexural strength, it increased from 33.3 kg/cm2 without fiber to 41.4 kg/cm2 with 4% fiber, and 50.6 kg/cm2 with 7% fiber. And, finally, the modulus of elasticity improved from a deformation of 24.9 GPa without fiber to of 25.2 GPa with fiber at 4% and 25.6 GPa at 7%. Finally, the thickness of the Whitetopping pavement was calculated based on the traffic study and all the variables defined in the equation established by AASHTO 93, where it was obtained that the thickness of the Whitetopping pavement is to 17 cm, therefore, a slim whitetopping was achieved. It was concluded that, with the use of synthetic fiber in the whitetopping concrete, the properties of the concrete were improved.
