This work analyzes the theoretical or geometric IRI (International Roughness Index), which is the IRI specific to the geometry of the road that determines from the beginning the final result of the real IRI at grade level. The one kilometer study section is located in the progressive sections from km 191+000 to km 192+000 of section 2 of the Oyón – Ambo highway. With the information from the technical file, the profile of the road at grade level was obtained, through the use of AutoCAD Civil 3D software, generating the axis of the road with a 6.60 m carriageway with two lanes in both directions. On these lanes, the heights of the traffic tracks were determined every 25 cm, located at 0.70 m and 2.60 m from the axis of the road. Using the data from the heights of the traffic tracks, the geometric IRI was calculated using the ProVAL 3.61 software, obtaining average values in the range of 0.85 m/km to 1,539 m/km. Finally, the elevation tolerance of ± 5mm established by the EG-2013 was considered randomly, thus generating new average values of the geometric IRI in the range of 4,362 m/km to 5,566 m/km. Those have shown that the value of the geometric IRI is affected when considering transitions and curves, as well as random tolerance ranges, so they should be taken into account as unique situations on roads with restricted geometry.
