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 M 140@ M 208@ and M 316@ and with temperatures between 25??and less than 90??(77??and less than 194??. Note 1??The viscometer makes measurements at 25??(77??@ 40??(104??@ 50??(122??@ 80??(176??@ and 90??(194?? 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). The values stated in SI units are to be regarded as the standard. The values given in parentheses are for informational purposes only. This standard does not purport to address all of the safety concerns@ if any@ associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
