In this thesis work, the correlation between the indicators Pavement Condition Index (PCI) and International Roughness Index (IRI) of the flexible pavement, in the section of the road network 28B Calca-Cusco, is proposed and investigated. Two methods were used to determine the IRI; the Merlin Roughness Meter and the Roadroid mobile application. For this 4.1 km study, the section was divided into two sections, corresponding to the LamayCoya road as the outbound section and Coya-Lamay as the return. For each section, 82 sampling units were obtained for the PCI study, 41 sampling units for the Roadroid application and 11 sampling units for the Merlin Roughness Meter. The readings for the IRI using the Merlin Roughness Meter correspond to 5.48 m/km for the outbound section and 5.92 m/km for the return section. Both respond to "very bad" pavement surface roughness. The IRI readings using Roadroid correspond to 3.39 m/km eIRI and 4.68 m/km cIRI for the outbound section, corresponding to 3.59 m/km Eri and 5.20 m/km Cri for the outbound section. Both sections correspond to "bad" and "very bad" pavement roughness, respectively. The values obtained for PCI correspond to 15.74 for the outbound section, and 13.40 for the return section, both values signify a "very bad" pavement condition. The study carried out indicated the degree of dependence that the pavement indicators will have, obtaining correlation coefficients PCI-IRI (obtained from Merlin Roughness Meter) with a value of 0.5236 corresponding to a strong correlation, PCI-eIRI with a value of 0.4653 corresponding to a moderate correlation and PCI- cIRI with a value of 0.3455 corresponding to a moderate correlation. Due to the fact that in the use of the Roadroid mobile application, a speed between 60-80 km/h was not constantly reached in the car, the values for PCI-cIRI will not be representative for this study.
