AASHTO T 59-22

These test methods, given under the headings titled Composition, Consistency, Stability, Examination of Residue, Identification Tests, Coating Tests on Emulsified Asphalts, and Density of Emulsified Asphalts, cover the examination of emulsified asphalt composed principally of a semisolid or liquid asphalt base, water, and an emulsifying agent. The methods cover the following tests:

• Composition: Water Content, Residue and Oil Distillate by Distillation, Emulsified Asphalt Residue by Evaporation, Particle Charge of Cationic Emulsified Asphalts
• Consistency: Viscosity
• Stability: Demulsibility, Settlement, Cement Mixing, Sieve Test, Coating Test, Coating Ability and Water Resistance, Storage Stability of Emulsified Asphalt
• Examination of Residue: Specific Gravity, Ash Content, Solubility in Trichloroethylene, Penetration, Ductility, Float Test
• Identification Tests: Identification Test for Cationic Rapid-Setting (CRS) Emulsified Asphalts, Identification Test for Cationic Slow-Setting (CSS) Emulsified Asphalts
• Coating Tests on Emulsified Asphalts: Field Coating Test, Emulsified Asphalt/Job Aggregate Coating Test
• Density of Emulsified Asphalts: Test to Determine Mass per Liter (Gallon)
