ASTM E1926-98
Historical Standard: ASTM E1926-98 Standard Practice for Computing International Roughness Index of Roads from Longitudinal Profile Measurements
SUPERSEDED (see Active link, below)
ASTM E1926
1. Scope
1.1 This practice covers the mathematical processing of longitudinal profile measurements to produce a road roughness statistic called the International Roughness Index (IRI).
1.2 The intent is to provide a standard practice for computing and reporting an estimate of road roughness for highway pavements.
1.3 This 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). Additional technical information is provided in two TRB papers (3) (4).
1.5 This 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.
2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
