ASTM D244-23 PDF

SIGNIFICANCE AND USE 5.1 This test method measures the amount of water present in the emulsified asphalt, as distinguished from either bitumen or petroleum solvent. SCOPE 1.1 These test methods and practices, given under the headings titled Composition, Consistency, Stability, and Examination of Residue, cover the examination of asphalt emulsions composed principally of a semisolid or liquid asphaltic base, water, and an emulsifying agent. The test methods cover the following tests and practices: Test Sections Composition: Water Content 4 – 10 Residue and Oil Distillate by Distillation See Test Method D6997 Residue by Evaporation See Test Method D6934 Particle Charge of Cationic Emulsified Asphalts See Practice D7402 Consistency: Viscosity (Saybolt Furol) See Test Method D7496 Stability: Demulsibility See Test Method D6936 Settlement See Test Method D6930 Cement Mixing See Test Method D6935 Sieve Test See Test Method D6933 Aggregate Coating See Practice D6998 Miscibility with Water See Practice D6999 Freezing See Practice D6929 Coating Ability and Water Resistance 11 – 18 Storage Stability of Asphalt Emulsion See Test Method D6930 Examination of Residue 19 – 26 Identification Test for Rapid Setting Cationic Emulsified Asphalt 27 – 34 Identification of Cationic Slow Set Emulsions See Practice D7402 Field Coating Test on Emulsified Asphalts 35 – 40 Emulsified Asphalt/Job Aggregate Coating Test 41 – 46 Density of Emulsified Asphalt See Test Method D6937 Residue by Low-Temperature Vacuum Distillation See Test Method D7403 1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only. 1.3 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. 1.4 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.
