HMAC Changes to the Level 1A Program - Effective August 2016

The Level 1A Plant Production Specialist certification program prepares individuals to sample and test hot mix asphalt produced at the plant in accordance with TxDOT Test Procedures and Specifications. 

Starting this August, the Hot Mix Asphalt Center (HMAC) will no longer offer the week-long training/certification class. All individuals seeking certification will attend a one-day certification class where they will have to successfully complete an individual performance evaluation (examination) and pass the written examination.

The individual performance evaluation requires actual demonstration of the required TxDOT test procedures. The evaluation is judged on the individual’s ability to correctly perform (or describe, where allowed) the test procedure.

The two-hour written examination is open-book and consists of 100 multiple-choice questions. To pass the written examination the individual must score an 80 or above.
