Relationship between International Roughness Index and Straightedge Index
Journal of Transportation Engineering, 2012AbstractThis study presents the regression relationships between two commonly used indicators of longitudinal road unevenness, the international roughness index (IRI) and the straightedge index. A total of 290 real longitudinal road-profile records were processed. The asphalt-concrete and cement-concrete road surfaces were analyzed separately.

Smooth Enough?: Estimated Roughness on Roads with Low International Roughness Index Values [PDF]
Transportation Research Record: Journal of the Transportation Research Board, 2003 The reported investigation is one part of a project concerning methods for measurement of the longitudinal roughness of roads and the necessary accuracy. In this study the main focus was on the subjective experience of roughness on roads with low international roughness index (IRI) values, that is, fairly good roads. With the available data it was also

Applicability of the International Roughness Index as a Predictor of Asphalt Pavement Condition [PDF]
Journal of Transportation Engineering, 2007 This note establishes the relationship between the surface distress of an asphalt pavement and its roughness, as conveyed respectively by the pavement condition index (PCI) and the international roughness index (IRI). The DataPave software provides the roughness of varied roadway pavement sections from the North Atlantic region that were investigated ...

IRI (International Roughness Index): An Indicator Of Vehicle Response
Materials Today: Proceedings, 2018Abstract Public roads are the principle source of excitation to ground vehicles. Objective roughness/severity classification of the public roads is essential to predict vehicle response/fatigue damage at an early stage of vehicle development program.

Factors Contributing to Differences between Profiler and the International Roughness Index [PDF]
Transportation Research Record: Journal of the Transportation Research Board, 2006 One of the data elements included in a pavement management system is the roughness of each highway segment. State highway agencies use inertial profilers to collect profile data of the pavements and then use these data to compute the International Roughness Index (IRI) of each highway segment.
