Joint Training and Certification Program (JTCP)
California Hot Mix Asphalt and Aggregate Technicians To Be Certified by JTCP
The second and final pilot training a certification class finished December 15, 2017 and now California materials testing technicians are going to be certified through JTCP for certain test methods. Previously, technician certification was completed through Caltrans independent Assurance (IA) group. Now the JTCP program administered by California State University, Long Beach (CSU Long Beach) is tasked with certification for certain hot mix asphalt (HMA), aggregate and soil test methods used in construction materials quality control and quality assurance laboratory testing. JTCP certifies technicians for test methods in bundles included in each of three modules. Each JTCP module includes training developed by CSU Long Beach and industry partners administered by pre-qualified instructors, and examination by Caltrans IA staff. Successful completion of training and demonstration of tests included in each module, results in a three year certification for all methods included in a module.
Available modules:
- HMA I
- HMA II
- Soil and Aggregate
- Portland Cement Concrete Certification completed via American Concrete Institute (ACI) Field Grade I certification
