AASHTO T 382-22 PDF

This test method utilizes a rotational paddle viscometer to measure the viscosity of emulsified asphalt. It is applicable to all the emulsified asphalts described in AASHTO M 140, M 208, and M 316, and with temperatures between 25°C and less than 90°C (77°F and less than 194°F).

Note—The viscometer makes measurements at 25°C (77°F), 40°C (104°F), 50°C (122°F), 80°C (176°F), and 90°C (194°F) without any external ancillary equipment and with a temperature probe directly in the liquid sample. The viscosity measurement range is from 30 mPa∙s to 3000 mPa∙s (30 to 3000 cP).

This standard was formerly designated as provisional standard TP 121.
