ASTM D8292-20

Standard Test Method for Permanent Deformation Behavior and Rutting Resistance of Compacted Asphalt Mix in the Modified Loaded Wheel Tracker Test Utilizing Controlled Confining Pressure

SIGNIFICANCE AND USE
5.1 This test method measures the permanent deformation behavior and rutting resistance of an asphalt mixture specimen.  
5.2 This method can also measure moisture susceptibility of an asphalt mixture specimen if required by the agency.
Note 1: The quality of the results produced by this standard are dependent on the competence of the personnel performing the procedure and the capability, calibration, and maintenance of the equipment used. Agencies that meet the criteria of Specification D3666 are generally considered capable of competent and objective testing, sampling, inspection, etc. Users of this standard are cautioned that compliance with Specification D3666 alone does not completely ensure reliable results. Reliable results depend on many factors; following the suggestions of Specification D3666 or some similar acceptable guideline provides a means of evaluating and controlling some of those factors.
SCOPE
1.1 This test method describes a procedure for testing permanent deformation behavior and rutting resistance of compacted asphalt mixtures using a modified version of a loaded wheel tracker device2 utilizing controlled confining pressure. The test specimen is tested either dry or moisture conditioned. A laboratory roller compactor or its equivalent is used to prepare test slabs of 305 mm by 305 mm [12 in. by 12 in.] and thickness 50 mm, 75 mm, or 100 mm [2 in., 3 in., or 4 in.] depending on the nominal maximum aggregate size. The thickness of the specimen must be at least two and half times the nominal maximum aggregate size. Alternatively, saw-cut slab specimens with dimensions 305 mm by 305 mm [12 in. by 12 in.] and thickness 50 mm to 100 mm [2 in. to 4 in.] may be secured from the field.  
1.2 Units—The values stated in either SI units or inch-pound units are to be regarded separately as standard. The values stated in each system may not be exact equivalents; therefore, each system shall be used independently of the other. Combining values from the two systems may result in nonconformance with the 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 Since a precision estimate for this standard has not been fully developed, the test method is to be used for research and informational purposes only. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.  
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.
