ASTM D8159-19 PDF Download

ASTM D8159-19 provides a standard test method for the automated extraction of asphalt binder from asphalt mixtures. This test method is used to determine the quantitative asphalt binder content in asphalt mixtures and pavement samples, allowing for specification acceptance, service evaluation, quality control, and research purposes.

The extracted aggregates obtained from this method can also be used for sieve analysis using Test Method D5444. Additionally, the extracted asphalt binder can be recovered using Test Method D1856 or Practice D5404/D5404M.

It is important to note that the quality of results obtained from this standard is dependent on the competence of the personnel performing the procedure and the calibration and maintenance of the equipment used. Compliance with Specification D3666 does not guarantee reliable results. Factors such as testing, sampling, and inspection should be evaluated and controlled according to the suggestions of Specification D3666 or similar acceptable guidance.

This standard references notes and footnotes for explanatory material, which should not be considered as requirements. Furthermore, it is highlighted that an Interlaboratory Study (ILS) is being conducted according to Practice E691 and will be available by December 2018. Therefore, this standard should not be used for acceptance or rejection of materials for purchasing purposes until the ILS is completed.
