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:

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
