Steven E. Lenker, P.E. Director, Construction Materials Reference Laboratories AASHTO Materials Reference Laboratory Cement & Concrete Reference Laboratory • • • • Laboratory Assessment Program Proficiency Sample Program AASHTO Accreditation Program NTPEP Manufacturer Audit Program What is a Laboratory Assessment? • Full and thorough check of all equipment required to perform tests • Full demonstration of each procedure laboratory elects to present • Direct comparison between laboratory and AASHTO and ASTM standard test methods and specifications • Thorough check of laboratory quality system AMRL Laboratory Assessment Program • Completed 26th Assessment Tour in April, 2008 which included 1360 laboratory assessments • The 27th Tour began in May, 2008 and will likely include assessments of more than 1500 laboratories.

This is over a 100% increase as compared to CY’ 2001. Laboratory Assessment Program Assessor Productivity AMRL Proficiency Sample Programs • 14 different types of proficiency samples • Pairs of samples are sent to all participants for testing • Participants complete tests and send AMRL results AMRL Control Chart AMRL Proficiency Sample Programs Number of Participants PSP Aggregate Participation 1500 1400 1300 1200 1100 1000 900 800 700 600 500 400 300 200 100 0 84 86 88 90 92 94 96 Year 98 00 02 04 06 08 The AASHTO Accreditation Program The standard by which others are measured.
