ASTM D7113/D7113M : 24

1.1 This test method covers the procedures for determining the in-place density and relative compaction of asphalt pavement mixtures by an electromagnetic surface contact device by measuring changes in the electromagnetic field resulting from the compaction process.

1.2 The equipment referenced in this method is a surface contact device, which must accommodate surface moisture and temperature variation in the range typically encountered in paving applications. This can be accomplished by design parameters that reduce the device’s sensitivity to surface moisture and temperature variation or by measurements and algorithms to account for surface moisture and temperature variance in the rolling pattern.

1.3 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.

1.4 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.

1.5 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.
