Determinación del índice de rugosidad internacional de la malla vial de BOGOTÁ

Abstract

The International Roughness Index (IRI) was proposed by the World Bank in 1982 as a statistical standard of roughness and has served as a parameter of Reference of the measurement of the quality of the rolling of the roads at level international. With the passage of time has spread its application to the roads Urban, however, these present a number of singularities as they are Construction processes, traffic management, presence of intersections, accesses To buildings, geometry, types of ways and speeds of operation, existence of networks Of public services, presence of horizontal signage, and conditions Traffic in cities, among other aspects. In some routes of the main arterial vial mesh of the city of Bogota has been Presented a problem for the measurement of this index, since the Exclusion of some of the singularities mentioned, brings about the Considerable reduction of homogeneous and continuous sections to evaluate this index That can represent the regularity of the pavement of the entire road in Study, in addition to drawbacks, in some cases, to obtain the thresholds Of IRI required by the contracting entity that acts as road manager. Taking into account the interest of the IDU to obtain information on parameters Conditions of the pavement of the Bogotá, the lifting, processing and analysis of Surface, functional and structural information of the pavement structures of The elements of road that make up the road network of Bogota.
