The Hot Mix Asphalt (HMA) Level 2 Job Mix Technician course is intended to cover the concepts and preparation procedures of HMA job mix formula (JMF).  Individuals who complete this course will be re-certified to perform HMA Level 2 Job Mix Technician duties for SCDOT projects.  The re-certification course includes a general overview as well as a review of all specification and procedural changes that may have occurred.  Each participant is also responsible for performing mathematical calculations related to the JMFs.  The instructors for the course are made up of knowledgeable asphalt industry consultants, academia, contractors and SCDOT representatives.

Entry Requirements/What to Expect
Prerequisites

  • Current HMA Level 2 Job Mix Technician Certification

Frequency of Re-certification
The certification period is five years. An individual will be informed, by way of a letter mailed to the technician's last address of record, when the certification period is nearing the expiration date. If the technician was last registered for certification by his/her employer, the last address of record may be the employer's address. However, it is the responsibility of the individual to keep Tri-County Technical College and the Technician Certification Board advised of his/her current address. The individual is also responsible for registering for the re-certification course, attending the re-certification course, and passing the written exam with a score of 80% or higher.

Additional Requirements
On a yearly basis, to maintain certification and to continue to be able to submit JMFs to SCDOT, each HMA Level 2 Job Mix Technician must submit the results of his/her annual AMRL proficiency samples to Myrtle Mraovich at Tri-County Technical College via fax at 864-646-1894.  See the SCDOT Technician Certification Policy for more details.

Re-certification Date Policy (as of June 2005)
The SCDOT Technician Certification Board hereby requests that the certification expiration dates for re-certifications obtained within one year prior to the technician's original date of expiration be issued based on the original expiration date. For example, if a technician's certification expires April 2006, and that technician passes a re-certification exam in April 2005, his/her certification will be extended five years from the original April 2006 date to April 2011. However, if that technician chooses to attend a re-certification course in March 2005 and passes the exam, the re-certification will be valid from March 2005 to March 2010 (because the technician passed the exam outside of the one-year window). If that technician does not obtain the re-certification before April 2006, then his/her certification expires on that date.
