【国外标准】 Standard Test Method for Automated Extraction of Asphalt Binder from Asphalt Mixtures

4.1 This test method is used for quantitative determination of asphalt binder in asphalt mixtures and asphalt pavement samples for specification acceptance, service evaluation, control, and research.4.2 Aggregates obtained by this method may be used for sieve analysis using Test Method D5444. Extracted asphalt binder from this test method may be recovered using Test Method D1856 or Practice D5404/D5404M.NOTE 1: The quality of results produced by this standard is 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 guidance provides a means of evaluating and controlling some of those factors.1.1 This test method covers the quantitative determination of asphalt binder content in asphalt mixtures and pavement specimens, using the automated computer controller or human-machine interface system (HMI), to perform a solvent extraction for specification acceptance, service evaluation, quality control, and research.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 An ILS is being conducted according to Practice E691 and will be available on or before December 2018. 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.
