    Abstract - (Show below) - (Hide below)

    CONTAINED IN VOL. 04.03, 2015 Specifies the mathematical processing of longitudinal profile measurements to produce a road roughness statistic called the International Roughness Index (IRI).

    Scope - (Show below) - (Hide below)

    1.1This practice covers the mathematical processing of longitudinal profile measurements to produce a road roughness statistic called the International Roughness Index (IRI).

    1.2The intent is to provide a standard practice for computing and reporting an estimate of road roughness for highway pavements.

    1.3This practice is based on an algorithm developed in The International Road Roughness Experiment sponsored by a number of institutions including the World Bank and reported in two World Bank Technical Papers (1, 2).2 Additional technical information is provided in two Transportation Research Board (TRB) papers (3, 4).

    1.4The values stated in SI units are to be regarded as the standard. The inch-pound units given in parentheses are for information only.

    1.5This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
