Abstract:

This digest summarizes the findings of research conducted between January 2007 and June 2009 in NCHRP Project 9-26A to recommend new or updated precision statements of the AASHTO standard methods of test T 22, T 104, T 105, T 154, T 186, and T 242. These specific precision statements were developed through statistical analysis of multi-year results obtained from (1) the Proficiency Sample Programs (PSP) of the AASHTO Materials Reference Laboratory (AMRL) and the ASTM Cement and Concrete Reference Laboratory (CCRL) and (2) calibration testing of state friction measurement systems at field test centers at the Texas Transportation Institute, College Station, Texas, and the Transportation Research Center, East Liberty, Ohio.
