The Oregon Department of Transportation has established a Quality Assurance Program for quality control and quality assurance construction of transportation facilities. The purpose of the Technician Certification Program is to develop and maintain a pool of well-trained technicians to perform field-testing of materials for both Quality Control and Quality Assurance. All technician certification programs must be approved by the Certification Advisory Committee. ODOT's Quality Assurance program requires all personnel and laboratories performing materials testing to be certified. This requirement applies to project personnel working as technicians for the State, Contractors, or Consultants on such projects.
ODOT is a member of the Western Alliance for Quality Transportation Construction (WAQTC) which consists of 11 western states committed to the quality of our transportation systems. WAQTC has developed a technician-training program which is comprised of instructional and student modules used to assist in the training process of material field-tested procedures. ODOT has adopted the training packages for all (material testing) certifications except for ODOT-specific certifications/requirements and those controlled by entities other than WAQTC, such as:

Technicians are required to pass a written and/or a practical test demonstrating a knowledge and understanding of how to perform the specific tests. All tests shall be administered and evaluated only by evaluators approved by the Certification Advisory Committee Chair, or their designated representative.

A description of each technician certification is provided below with a link to register for the required training. • Certified Aggregate Technician or WAQTC equivalent: A CAgT performs a variety of tests on aggregates including sieve analysis, fracture, sand equivalency, and other tests. A CAgT also performs other duties as required by current specifications for aggregate materials. Certification duration: Initial – 3 years; Recertification – 5 years. Register for CAgT training. • Certified Embankment and Base Technician or WAQTC equivalent: The CEBT performs testing of soils and aggregates for establishing the relative maximum density and optimum moisture for use in compaction testing of subgrade soils and aggregate bases. A CEBT also determines the specific gravities of aggregate. Certification duration: Initial – 3 years; Recertification – 5 years. Register for CEBT training.
• Certified Flagger: ODOT has designated the Chemeketa Community College Center for Business and Industry as the administrator of flagger curriculum, materials and flagger certification cards. To find out more about flagger certification classes is your area visit the Oregon Flagger Certification Program webpage. • Certified Density Technician or WAQTC equivalent: A CDT performs in-place density testing of soils, aggregates and asphalt mixtures using the nuclear density gauge. In addition to certification, a CDT must possess a current Radiation Safety Card issued by an approved source. For soil, soil aggregate mixtures and aggregates, a CDT determines percentages of coarse and fine material, performs one-point testing and related calculations. Certification duration: Initial – 3 years; Recertification – 5 years. Register for CDT training. • Certified Asphalt Technician I or WAQTC equivalent: A CAT-I performs sampling and testing for ACP and EAC mixtures including AC content, maximum specific gravity, sieve analysis, volumetric measurements, and other tests and duties as required by current specifications. Certification duration: Initial – 3 years; Recertification – 5 years. Register for CAT-I training. • Certified Asphalt Technician II: A CAT-II is responsible for managing the volumetric properties of asphalt mixes by controlling plant operations, for troubleshooting ACP sampling and testing processes, and for making appropriate adjustments to ACP production and laydown procedures. Certification at CAT-II level is contingent on having successfully completed the CAT-I certification at least once. Certification duration: Initial and recertification – 3 years. Register for CAT-II training. • Certified Mix Design Technician: A CMDT is responsible for preparing ACP and EAC mix designs, including all material testing and data analysis necessary to properly complete a design. A CMDT prepares designs for both dense and open-graded ACP mixtures. Certification duration: Initial – 3 years; Recertification – 2 years. Register for CMDT training. • Quality Control Technician: A QCT performs testing of fresh Portland cement concrete including sampling, concrete temperature, slump, unit weight, air content, and fabrication of specimens for strength testing, and performs other duties including calculating cement content and water-cement ratio as required by specifications. QCT certification may be obtained through the American Concrete Institute Concrete Field Testing Technician – Grade 1 certification program, with the Oregon written supplement, conducted by the Oregon Concrete and Aggregate Producers Association. Certification duration: Initial and recertification – 5 years. Register for QCT training. • Concrete Control Technician: A CCT is responsible for proportioning concrete mixtures to meet job requirements and for making adjustments to the mix design as necessary to provide a concrete mixture of the quality required by specifications. A CCT certification may be obtained through a program conducted through Oregon Concrete and Aggregate Producers Association. Certification duration: Initial and recertification – 3 years. Register for CCT training. • Concrete Strength Testing Technician: A CSTT is responsible for testing the compressive or flexural strength of hardened concrete cylinders or beams. The duties of a CSTT include proper capping of specimens (bonded and unbonded), correct operation of breaking device, and visual evaluation of broken specimens. Also, the CSTT is responsible to ensure the proper handling, mold removal, logging and curing of field fabricated samples upon arrival at the laboratory. A CSTT certification may be obtained through a program conducted by the Oregon Chapter of the American Concrete Institute. Certification duration: Initial and recertification – 5 years. Register for CSTT training.
Recertification is necessary after the original certification expiration date. Certified Technicians must obtain recertification before the expiration date of the certification. Recertification may only be obtained by passing the written and/or practical test required for that particular certification. A Certified Technician must apply for the appropriate certification. The Certified Technician is responsible for scheduling his/her own written and/or practical comprehensive examination. Should a technician fail to successfully complete a Certification renewal in a specialty area, the technician will be considered disqualified in that area, until the requirements for Certification renewal have been successfully met.
The following is a sample of the Technician Rights and Responsibilities Agreement. Each certification has a specific agreement designed for that discipline. This document affirms that __________________________________, hereinafter the Technician, desires to be certified by the Oregon Department of Transportation as a ______________________________________. This certification carries inherent rights and responsibilities. These rights include being exclusively sanctioned along with others so certified by ODOT to perform sampling, testing, and reporting of test results for quality control and quality assurance programs. These responsibilities include performing and reporting tests with the accuracy and precision expected of the Technician in accordance with the required test procedures. Abuse of these rights and responsibilities shall be penalized upon recommendation by the Certification Advisory Committee Chair. Penalties, as prescribed herein, may be assessed for abuse of the rights and prerogatives conferred upon the Technician by this certification. Abuse is defined as intentional deviations from approved procedures. A finding of abuse shall result in a one year suspension of certification. Any subsequent instance of abuse shall result in permanent revocation of certification. Permanent revocation of certification shall result in that person being ineligible for any ODOT certification at any level. I, ________________________________, have read, understand and agree to abide by the rights, responsibilities and penalties and affirm that this warrant expires no later than three (3) years from the date of execution.
