The objective of this work is to analyze the influence of the geometry related to the International Roughness Index (IRI) indicator in section II of the improvement of the Oyón – Ambo highway sector Km. 181+000 – Km. 188+000 in order to plan the conservation and maintenance of said road, for this it is proposed to establish ranges of the IRI indicator in the regulations of the transport sector, since the execution of said section is crossing mountainous regions, which are characterized by a rugged topography located above 4,700 m.s.n.m. and extreme temperatures of up to -40 ºC. Likewise, the IRI values exceed the threshold of IRI 3.0 indicated in the minimum technical requirements of the technical file by 83.33%. This translates into a longitudinal profile of the roads with many sharp curves, steep slopes and short distances to make inclined curves, since the highest IRI value is 4.835 with a radius of 70 and curve length of 49.660, being the minimum IRI value 2.535 with a radius of 160 and curve length of 35.102, these geometric conditions lead to typically high IRI values, meaning that some sections will have high IRI values due solely to the geometric design. Likewise, information related to the execution of said section was analyzed, which served to determine the problems that exist in compliance with the IRI indicator due to geographical particularities and temperature change. The results showed non-compliance with the IRI more frequently in curves where there are smaller radii. As part of the proposal and according to the results obtained in the analysis, it is evident that there is a need to discuss how IRI thresholds should be evaluated on roads with extreme geometry and temperatures.
