Aggregate Technician Certification

About the Certification

The Aggregate Technician Certification Program was initially developed in 1997 in response to a Federal regulation stating:

“After June 29, 2000, all sampling and testing data to be used in the acceptance decision or the
independent assurance program will be executed by qualified sampling and testing personnel.”

Continuous improvements are being made to the program through a work group consisting of PennDOT personnel and PACA members and staff; who also serve as instructors and proctors for the program.

Requirements for the program and the retest process are highlighted in PennDOT Publication 725.

Courses are held at PennDOT's lab in Harrisburg, PA.

Dates for the course and course registration are hosted on the Northeast Center for Pavement Technology's (NECEPT) website.
