Methods of Testing Asphalt Emulsions

Immerse the plates to a depth of 1 inch (25.4 mm) in the emulsion sample, the current connected and adjusted to a flow of 8 to 10 milliamperes. When the current has dropped to 2 milliamperes, or at the end of 30 minutes, whichever occurs first, disconnect the current, and remove the plates from the sample and gently wash with distilled water. ................
