ASTM D6936-09
(Test Method)Standard Test Method for Determining Demulsibility of Emulsified Asphalt
Standard Test Method for Determining Demulsibility of Emulsified Asphalt
SIGNIFICANCE AND USE
This test method is used to identify or classify an emulsified asphalt as an RS or MS by measuring the amount of available asphalt that is broken from the emulsified asphalt by utilizing specified amounts and concentrations of calcium chloride solution for anionic emulsified asphalts and dioctyl sodium sulfosuccinate for cationic emulsified asphalts.
SCOPE
1.1 This test method, applicable to both anionic and cationic emulsified asphalts of the RS and MS type, measures the chemical breaking of the emulsified asphalt.
1.2 This test method 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.
1.3 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
