In Peru, most rigid pavements have various cracks. These are generated by poor maintenance management, by the high vehicular flow and by the thermal expansion and contraction of the concrete. From previous studies, the addition of PET fibers in concrete had a positive influence on its mechanical properties, as long as it did not exceed 0.50% fibers. For that reason, the main objective of this work is to carry out laboratory tests of concrete with percentages of 0%, 0.20%, 0.30% y 0.45% of PET corrugated fibers to opt for the most favorable one and model the rigid pavement using Kenpave software. To achieve this, the place of study was first selected, which was Av. Las Gaviotas, in Chorrillos and the current state of the rigid pavement was determined. Then, the designs of mixtures for each concrete with their respective percentage were made. The mixture designs of conventional concrete and concrete with the addition of PET fibers were tested at compressive, flexural and tensile strengths. With the results obtained, we proceeded to choose the best concrete with the addition of PET fibers to make a comparison with conventional concrete. Finally, the rigid pavements, which used these concretes, were modeled using Kenpave software. With this program, the stresses, deflections and useful life of rigid pavements were calculated. It is concluded that using 0.45% of PET corrugated fibers in concrete increases flexural and tensile strengths. While it tends to decrease its compressive strength, if more corrugated fibers are added to the concrete. Likewise, using the Kenpave software, it was estimated that the useful life of the pavement using concrete with 0.45% PET corrugated fibers was 26.41% higher than rigid pavement using conventional concrete.
