Significance and Use
4.1 This test is used for determining the amount of inorganic or non-organic materials in an asphalt or emulsified asphalt residue. The emulsified asphalt residue can be obtained by methods such as Test Methods D6934 and D6997, Practice D7497, AASHTO PP72, or other agency specified methods. This test may be useful as an alternative to solubility tests when a confounding material creates an interference to the solubility test being performed acceptably. An example of an interfering material is a polymer which may be incompatible with the solubility test solvent and plugs the filter.
Scope
1.1 This test method measures the ash content of an asphalt or emulsified asphalt residue.
1.2 A precision and bias statement for this standard has not been developed at this time. Therefore, this standard should not be used for acceptance or rejection of a material for purchasing purposes.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
1.4 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.
