ASTM WK26816

    New Test Method for Determining the Susceptibility of Asphalt Mixtures to Cracking Using the Overlay Tester

    (What is a Work Item?)

    Developed by Subcommittee: D04.20 | Committee D04 | Contact Staff Manager


    1. Scope

    1.1 This test method provides quantitative procedures for determining a failure point in load cycles at 25C (77F) related to the crack failure of asphalt mixture samples subjected to repeated loads using an overlay tester. Test specimens are fabricated from laboratory compacted bituminous mixtures. 1.1.1 Since a precision estimate for this test method has not been developed, this test method is to be used for research and informational purposes only. Therefore, this test method should not be used for acceptance or rejection of a material for purchasing purposes. 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. An exception is made for the mass of epoxy, which is measured in grams only. Standard inch-pound units for mass of epoxy in these quantities are not commonly used in asphalt mixture laboratories. 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 and health practices and determine the applicability of regulatory limitations prior to use. 1.4 The text of this standard references notes and footnotes that provide explanatory material. These notes and footnotes (excluding those in tables and figures) shall not be considered as requirements of the standard.

    Include specimen preparation details along with details for using the device to test asphalt mixtures. Other asphalt materials such as microsurfacing, slurry, cold-in-place recycled materials, and hot-in-place recycled materials may be added at a later date.
