ASTM D244-09

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 D 6997
Residue by Evaporation	See Test Method D 6934
Particle Charge of Cationic Emulsified Asphalts	See Test Method D 7402
Consistency:
Viscosity (Saybolt Furol)	See Test Method D 7496
Stability:
Demulsibility	See Test Method D 6936
Settlement	See Test Method D 6930
Cement Mixing	See Test Method D 6935
Sieve Test	See Test Method D 6933
Aggregate Coating	See Practice D 6998
Miscibility with Water	See Test Method D 6999
Freezing	See Practice D 6929
Coating Ability and Water Resistance	11-18
Storage Stability of Asphalt Emulsion	See Test Method D 6930
Examination of Residue	19-26
Identification Test for Rapid Setting Cationic Emulsified Asphalt	27-34
Identification of Cationic Slow Set Emulsions	See Test Method D 7402
Field Coating Test on Emulsified Asphalts	35-40
Emulsified Asphalt/Job Aggregate Coating Test	41-46
Density of Emulsified Asphalt	See Test Method D 6937
Residue by Low-Temperature Vacuum Distillation	See Test Method D 7403

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 and health practices and determine the applicability of regulatory limitations prior to use.

4.1 This test method covers the procedure for determining the water content of an emulsified asphalt by reflux distillation using a water trap.

11.1 This test method is intended to aid in the identification of asphalt emulsions suitable for mixing with coarse graded calcareous aggregates. It can be applied to other aggregates. (See Note 2).

19.1 Tests for specific gravity, ash content, solubility in trichloroethylene, penetration, ductility and float test are suggested for examination of the emulsified asphalt residue obtained by distillation or evaporation (see Test Method D 6934 and Test Method D 6997).

27.1 This practice covers a procedure for identifying rapid-setting cationic emulsified asphalts. Their inability to coat a specific silica sand distinguishes them from medium and slow setting cationic grades.
