"NB/SH/T 0978-2019 Determination of apparent viscosity of emulsification asphalt swirl/spin paddle Viscosity meter method" is an industry standard, published on June 4, 2019 and implemented on October 1, 2019. The standard specifies a method for measuring the apparent viscosity of emulsification asphalt using swirl/spin paddle Viscosity meter, suitable for emulsification asphalt with a viscosity range of 30 mPa · s to 1500 mPa · s. Its main technical content includes instrumentation requirements, test procedures, result calculation and precision requirements. Repeatability of this method can provide a scientific basis for quality control and performance evaluation of emulsification asphalt, and is widely used in road construction, asphalt modification and other fields.
