ROUND 1 HOT MIX ASPHALT LABORATORY MOLDED PROFICIENCY SAMPLE PROGRAM
All laboratories conducting tests for the Strategic Highway Research Program (SHRP's) Long-Term Pavement Performance (LTPP) program were required to be accredited by the American Association of State Highway and Transportation Officials (AASHTO's) Accreditation Program (AAP). AAP includes site inspections of equipment and procedures, and participation in applicable proficiency sample testing. A few critical LTPP tests were not addressed fully by the AAP, and LTPP staff decided to conduct supplemental testing. The Hot Mix Asphalt (HMA) Laboratory Molded Proficiency Sample Program is one of those supplemental tests. Round 1 testing provided within- and among-laboratory diametral resilient modulus data for tests performed in accordance with SHRP Test Protocol P07. The objectives included drafting single operator and multi-laboratory test precision statements in testing proficiency status for SHRP laboratories, and preserving test sample information for future analysis. Worksheets, supporting data, analyses, final comments, and conclusions are presented. A complete set of proficiency sample statements in AASHTO and American Society for Testing and Materials (ASTM) format are provided.
