Precision Estimates of AASHTO T 201, AASHTO T 202, and AASHTO T 49

This digest presents results of Task Order #2 of National Cooperative Highway Research Program (NCHRP) Project 10-87, “Precision Statements for AASHTO Standard Methods of Test.” This work was conducted to update precision estimates of three test methods pertaining to asphalt binder: T 201, “Kinematic Viscosity of Asphalts (Bitumens)”; T 202, “Viscosity of Asphalts by Vacuum Capillary Viscometer”; and T 49, “Penetration of Bituminous Materials." Using the computed precision estimates, new precision statements for the three test methods have been prepared and are presented in this digest.
