ASTM D3549/D3549M-18

Standard Test Method for Thickness or Height of Compacted Asphalt Mixture Specimens

SIGNIFICANCE AND USE
4.1 The thickness of a compacted asphalt mixture is often used as a construction check to ensure that the proper quantity of materials has been placed on a project, and to correct strength measurement on constant diameter specimens with varying heights.
Note 1: The text of this test method 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 test method.
Note 2: 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 covers determination of the thickness (or height) of compacted asphalt mixture specimens.  
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.  
1.2.1 Section 7.4 specifies SI units because they are the units used in the equations for Test Methods D1188 and D2726. Performing calculations without first converting any measurements made in inch-pound units to SI units in 7.4 will result in nonconformance with the standard.  
1.3 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.  
1.4 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.
