OBLITAS-GASTELO, Boris Enrique; MEDINA-CARDOZO, Ingrid Isabel  and  PAREDES-ASALDE, Carmen Rosa. International evenness index and pavement condition index for defining pavement serviceability levels. Iteckne [online]. 2021, vol.18, n.2, pp.170-175.  Epub May 16, 2022. ISSN 1692-1798.  https://doi.org/10.15332/iteckne.v18i2.2616.

The present research constitutes a systematic review of the literature on the evaluation methods of flexible pavements, IRI (International Roughness Index) and PCI (Pavement Condition Index) to determine the levels of serviceability in flexible pavements, during the last 15 years. A thorough search of sources under inclusion and exclusion criteria was used, from which 29 scientific articles indexed in recognized databases were selected. Through an information analysis matrix, we proceeded to work exclusively with twenty on which thematic categories were constructed around which the results of the research are proposed. This process made it possible to identify the main findings, making comparisons between the results and different or similar points of view of authors in order to draw conclusions. Among the main results, it was found that it is necessary to perform pavement surface evaluation methods in order to know the current condition of pavements and not to carry out activities without a technical criterion. Therefore, using methods such as IRI and PCI is of utmost importance to determine the current characteristics of pavements, for decision making regarding maintenance, reconstruction and rehabilitation of roads, achieving an adequate pavement infrastructure management system, investing resources effectively.

Keywords : International regularity index; pavement condition index; flexible pavement; levels of serviceability.
