ASTM D8078-18e1 PDF Download

ASTM D8078-18e1 is a standard test method used to determine the amount of inorganic or non-organic materials present in an asphalt or emulsified asphalt residue. This test can be used as an alternative to solubility tests when an interfering material, such as a polymer, makes the solubility test impractical. The emulsified asphalt residue for testing can be obtained through various methods specified by testing standards like Test Methods D6934 and D6997, Practice D7497, AASHTO R78, or other agency-specified methods.

Note 1 in the standard emphasizes that the quality of the results obtained from this test method depends on the competence of the personnel performing the procedure and the calibration and maintenance of the equipment used. Compliance with Specification D3666 alone does not guarantee reliable results, as several factors influence the accuracy of the test. However, following the suggestions of Specification D3666 or a similar guideline can help evaluate and control some of these factors.

The test method itself measures the ash content of the asphalt or emulsified asphalt residue, providing valuable information about the quantity of inorganic or non-organic materials present. The standard includes explanatory notes and footnotes, which are not considered requirements of the standard unless specified in tables and figures.
