ASTM D244 – Standard Test Methods and Practices for Emulsified Asphalts
Description:
Significance and Use
5.1 This test method measures the amount of water present in the emulsified asphalt, as distinguished from either bitumen or petroleum solvent.
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:
| Test | Sections |
| 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 |
1.2 The values stated in SI units are to be regarded as the standard. The values given in parentheses are for information only.
