Specifications include, but are not limited to: The Materials & Tests Division, through our technician training program, certifies annually approximately 1,500 students in testing of aggregate, asphalt, concrete and, the use of nuclear density gauges. The students are split between internal TDOT employees, contractors, local agency and Construction Engineering and Inspection (CEI) consultants . In the past, classes have been delivered in person with testing but because of COVID-19 this has been suspended. The Department has made progress in teaching the classes online but needs a solution to administer/proctor and secure the integrity of the test. While current circumstances are the major d river here, there is need for off schedule certifications t hat would be incorporated into this system moving forward even as we are able to return to in person sessions.
