AASHTO R 43
Standard Practice for Quantifying Roughness of Pavements
Year: 2013
Abstract: This standard practice describes a method for estimating roughness for a pavement section. An International Roughness Index (IRI) statistic is calculated from a single longitudinal profile measured with a road profiler in both the inside and outside wheel paths of the pavement. The average of these two IRI statistics (Mean Roughness Index, MRI) is reported as the roughness of the pavement section.
This standard practice recognizes the need for a quality assurance (QA) plan and proposes guidelines for the development of a QA plan.
Measurements of profile are made in accordance with ASTM E 950. If any part of this standard practice is in conflict with its referenced documents, such as ASTM standards or other AASHTO standards, this standard practice takes precedence for its purpose.
This standard practice 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 practice to establish appropriate safety and health practices and determine the applicability of regulatory limitations related to and prior to its use.
