Currently, there is inefficiency in road maintenance in Latin America, for example, in Chile and Peru. In Peru, the money allocated to road infrastructure is less than the 5% allocated to road maintenance. Therefore, in this research it is proposed to use the International Roughness Index (IRI) to provide a diagnosis of the state of conservation of the road based on the Highway or Road Conservation Manual. In addition, the Chille Highway Manual and manuals for the use of measuring equipment are also added to this standard, since there is a gap regarding the IRI methodology in the national regulations regarding events and singularities. For the sample, it was proposed to evaluate the road situation of the highway section II (Chinchaypujio - Cotabambas), a total of approximately 69.8 km. To measure the IRI on the track, the ARRB Roughness Meter III was used to read the section every 20 meters and the MARK IV Laser Profiler to calibrate these values as indicated by ASTM. The average track IRI was 3.99 m/km, while the calibration increased to 4.14 m/km. To evaluate the IRI, according to the Chilean manual, it must evaluate 5 homogeneous sections; For this reason, the road was divided into a total of 39 sections. On average, the IRIc was 4.50 m/km, showing that 14 sections have a permissible IRI, while 25 require maintenance to improve the rolling surface and vehicle comfort.
