Emulsified Asphalt Analysis (AASHTO M140)
Emulsified Asphalts are typically used as surface treatments and tack coats. They fall into four categories: quick setting, rapid setting, medium setting and slow setting. Emulsions can also be cationic and anionic. Depending on the type, several combinations of tests can be required to verify adherence to specification. Both the properties of the asphalt emulsion and the asphalt after distillation or evaporation are measured. Testing May Include:
- Saybolt Furol Viscosity 2 temperatures
- Storage and Stability
- Demulsibility
- Coating Ability and Water Resistance
- Cement Mixing Test
- Sieve Test
- Residue by Distillation or Evaporation
- Oil distillate by Volume of Emulsion
- Penetration of Residue from Distillation
- Ductility of Residue from Distillation
- Solubility
- Float Test
Cutback Asphalt Analysis (AASHTO M81/82)
Cutback Asphalts are commonly used in cold mixes or as prime applications. The two types are Rapid-Curing and Medium-Curing. Testing may include:
- Kinematic Viscosity
- Flash Point
- Water Percent
- Distillation Test
- Residue from Distillation
- Absolute Viscosity of residue
- Ductility of residue
- Solubility of residue
- Spot Test
