Research Report RR:D04-1037

    Research Report D04-1037 and D04-1038 presents the results of the Interlaboratory Study used to establish the precision and bias statement for ASTM D7226, Standard Test Method for Determining the Viscosity of Emulsified Asphalt Using a Rotational Paddle Viscometer. The collaborative study included respectively 14 labs and 15 labs who used method D7226 to analyze the viscosity of several types of emulsified asphalt of varying viscosity levels, including three different standards. The research report presents summary method performance statistics as well as the measurement data used to calculate results for the study.
