Levantamiento de línea base del Índice de Rugosidad Internacional (IRI) de la vía Intervalles

Abstract

Abstract:This paper presents a methodology to determine the International Roughness Index (IRI) applied to the Intervalles road located in the Loja canton, southern Ecuador. A type III Roughness Meter endorsed by the World Bank was used, which allows the registration of the IRI based on the irregularities registered by the sensor placed on the rear axle of a vehicle which must circulate with a speed range from 40 to 60 km/h. From the data obtained, it was determined that the road has an IRI value of 3.2 m/km, which is classified as an acceptable pavement. Knowing the IRI per lane, it was possible to establish a relationship where it was determined that the two lanes do not have the same wear, with the return lane being the most affected. The high IRI values correspond to 5 sections characterized by pavement failures. For future research, a temporal analysis should be carried out to define the pavement wear rate and propose maintenance measures in the short and medium term.
