Abstract

Abstract: In this project, the value of the International Roughness index (IRI) is determined on the Loja Yangana Road, both in the right and left lanes. For this, two measurements were made during the months of March and April. The equipment used is the Roughometer III, this device is installed in a vehicle and once it is correctly connected and ready, the road under research is being traveled by the vehicle at a speed between 60 - 80 km/h. For this project, the following results are obtained: for the first measurement, a value of 3.0 m/km is obtained in the right lane, while the left line resulted with a value of 1.8 m/km. For the second measurement, a value of 3.8 m/km was obtained in the right lane, and in the left lane a value of 2.2 m/km respectively. With these results, it is concluded that the road under study is in a range between excellent and good, given the fact that most of the route covered is in good conditions, but also taking into account that there are some parts of the road where IRI values reaches to values between 6 and 10 m/km, due to the effects of winte.
