Clarification of scope and consistent use of the phrase rotational paddle viscometer throughout the standard. 1. Scope 1.1 This test method utilizes the Rotational Paddle Viscometer to measure the viscosity of emulsified asphalt. It is applicable to all the emulsified asphalts described in Specifications D977 and D2397. 1.2 The values given in SI units are to be considered the standard. The values given in parentheses are for information only. 1.3 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 4. Summary of Test Method 4.1 The Rotational Paddle Viscometer for this test method is used to measure the apparent viscosity of emulsified asphalt at 50C (122F), 25C (77F) and other agreed-upon temperature. A microprocessor circuitry system functioning in tandem with a temperature probe and equipped with internal electronic sensors detects and analyzes the preset temperature. A paddle is immersed in the emulsified asphalt sample and is rotated at 100 RPM. The apparent viscosity of the sample is obtained and read from the electronic display or an optional printer.
