Abstract
International Roughness Index (IRI) has become a well-recognised tool and standard measurement of pavement riding quality. The IRI is also used by many road agencies as an end-result specification for newly constructed asphalt concrete pavements. As the IRI is a geographically transferable, repeatable, auditable, and time-stable means, it has been largely considered as a measure suitable for evaluating pavement performance evaluation. This paper describes analysis of IRI measurements provided by several contractors using different IRI measuring devices conducted on 12 representative pavement sections in Canada. Furthermore, the influence of different devices on IRI measurement is carried out through statistical analysis.
