| 摘要： | TRB’s National Cooperative Highway Research Program (NCHRP) Web Document 71: Precision Estimates for AASHTO Test Method T308 and the Test Methods for Performance-Graded Asphalt Binder in AASHTO Specification M320 includes the results of Phase 3 of NCHRP 9-26, in which data from the AMRL Proficiency Sample Program (PSP) are used to create or update precision estimates for a variety of test methods. These include those methods specified in AASHTO Standard Specification M320, “Performance-Graded Asphalt Binder,” and AASHTO Standard Test Method T308, “Determining the Asphalt Binder Content of Hot-Mix Asphalt (HMA) by the Ignition Method.” The report from Phase 1 of Project 9-26, which was published as NCHRP Web Document 54, includes precision estimates of selected volumetric properties of HMA using non-absorptive aggregates. The report from Phase 2, which was published as NCHRP Web Document 66, discusses the results of an investigation into the cause of variations in HMA bulk specific gravity test results using non-absorptive aggregates. |
