Background
In the early 90s, the transition to the Superpave PG asphalt binder system represented a significant step forward in our industry's ability to characterize asphalt performance properties. Now, after more than ten years of practical laboratory experience in PG testing, lab technicians have mastered techniques that yield excellent repeatability. However; repeatable results are not necessarily accurate results. Likewise, precise results in one lab may not be reproducible in other lab environments. And in one lab setting there may be no reason to question established techniques, but when results are compared between laboratories, variability may occur.

How do we overcome the inertia of variability?
Regional certification programs, such as the New England Transportation Technician Certification Program (NETTCP), have proven to be effective. However, currently there is no common technician certification program for all states and regions.

Serving the Asphalt Industry
The Asphalt Institute (AI) is pleased to announce a new National Binder Technician Certification (NBTC) program, debuting in 2008. The NBTC program is designed to address a recognized national need for expanded training in PG testing. This program will provide a consistent means of ensuring that asphalt binder technicians are knowl­edgeable and fully qualified to produce valid specification compliance and quality assurance data.

AI has been active in technical training in the field of asphalt technology since the 1920s. In recent years, the Institute has hosted hundreds of training and certification courses and taught thousands of students. Drawing from this experience and input from recognized centers of excellence nationwide, AI is prepared to provide a comprehensive, standardized, best practice protocol for PG asphalt binder testing.

The text for the NBTC program, MS-25 Asphalt Binder Testing, was introduced by AI in February 2007. Drawing on the practical laboratory expertise of AMRL, FHWA, Asphalt Institute and leading industry experts, MS-25 is the comprehensive link between standards and the technician – providing essential information needed to perform PG system tests. It also covers terminology, handling asphalt binders and temperature measurements.

What are the potential benefits and results of trained technicians who demonstrate the ability to produce accurate data?

• More concise interpretation of standard methods
• Standard laboratory best-practice
• Less retesting
• Quicker trouble shooting
• Reduced penalties, deducts and disputes
• Greater confidence in data for use in product development
• Reduced variability in published standards
• Streamlined PG plus requirements.
