AASHTO T 59-08

These test methods, 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 asphalt base, water, and an emulsifying agent. The methods cover the following tests:

• Composition: Water Content, Residue and Oil Distillate by Distillation, Identification of Oil Distillate by Micro-Distillation, Residue by Evaporation, Particle Charge of Cationic Emulsified Asphalts
• Consistency: Viscosity (Saybolt Furol)
• Stability: Demulsibility, Settlement, Cement Mixing, Sieve Test, Coating Test, Miscibility with Water, Freezing Test, Coating Ability and Water Resistance, Storage Stability of Asphalt Emulsion
• Examination of Residue: Specific Gravity, Ash Content, Solubility in Trichloroethylene, Penetration, Ductility, Float Test
• Identification Test for Rapid-Setting Cationic Emulsified Asphalt
• Identification of Cationic Slow-Set Emulsions
• Field Coating Test on Emulsified Asphalts
• Emulsified Asphalt/Job Aggregate Coating Test
• Weight per Gallon of Emulsified Asphalt
