Certification is achieved once both a written examination and a laboratory proficiency examination are passed. Certification is valid for five (5) years.

To become a Certified Binder Technician, a candidate, must have work experience with the testing of asphalt binders for compliance with the PG specification (AASHTO M320).  Candidates must have either six (6) months of experience or sixty (60) days working directly under an NBTC or NETTCP certified technician before attempting to achieve certification.
How to Apply

Once a technician decides to pursue certification, he or she first needs to complete an application form. An Asphalt Institute (AI) representative will then contact the technician to schedule attendance at an upcoming certification course if qualified or advise on next steps if not.

Certification courses and examinations are conducted at the Asphalt Institute Laboratory in Lexington, Kentucky and at host sites throughout the United States and Canada. Every person entering Laboratory space must wear safety glasses and a lab coat. Individuals who wear glasses must wear side shields. AI will supply required PPE, but welcomes students to bring their own PPE to ensure comfort and fit.



This certification program has a capacity for up to 13 students per event. Because of practical exam scheduling constraints, all registrants beyond the eighth must plan to finish on Friday AM.
