|Significance and Use|
5.1 The viscosity of emulsified asphalts characterizes their flow properties and affects their utility at 50 °C or at other temperatures. The sprayability and workability of an emulsified asphalt are directly related to its viscosity for many applications. The material must be thin enough to be sprayed yet thick enough such that it will not flow from the crown or grade of the road. For mixing-grade emulsified asphalts, the viscosity will affect its workability and resulting film thickness on the aggregate. This test method is useful to measure the apparent viscosity of emulsified asphalt at a temperature of 50 °C, 25 °C, or another agreed-upon temperature. The preset temperature and rotational speed at 100 r/min allow for an automated and consistent determination of an emulsified asphalt viscosity within a short time.
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 and .
1.2 The values stated in SI units are to be regarded as standard. No other units of measurement are included in this standard.
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, health, and environmental practices and determine the applicability of regulatory limitations prior to use.
1.4 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
