Abstract:
Understanding the precision of a test method is important to aid in evaluating the expected level of agreement in test results on like materials when performed either in a single lab or across multiple labs. Every test will be subject to some level of random errors; additionally, systematic factors or other factors impacting the test result could exist and also produce imprecision.
Recently developed draft test methods Tex-122-E and Tex-134-E establish full-depth reclamation (FDR) mixture designs for asphalt emulsion and foamed asphalt treatments, respectively, using the indirect tension test. This product describes the methods and results from measuring the current level of precision using these draft methods.
