Scope

1.1 This test method covers the procedures for preparing, testing, and measuring asphalt mixture rutting resistance at high temperatures using cylindrical laboratory-prepared asphalt mix samples or pavement cores. The test method describes the determination of the rutting tolerance index, RTIndex, and other parameters determined from the loaddisplacement curve. These parameters can be used to evaluate the resistance of asphalt mixtures to rutting. 1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard. 1.3 The text of this standard references notes and footnotes which provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard. 1.4 The within-laboratory repeatability standard deviation of rutting tolerance index has been determined to be 2.42, based on two labs, 30 test replicates, and ten different samples. The between-laboratory reproducibility of this test method is being determined and will be available on or before December 31, 2026. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purpose. 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, health, and environmental practices and determine the applicability of regulatory limitations prior to use. 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
