Hot Mix Asphalt (HMA) Level 1 Technician Recertification

The Hot Mix Asphalt (HMA) Level 1 Quality Control (QC) Technician Course is intended to assure an understanding of the requirements for inspection of asphalt materials at the plant, proper testing procedures, and related SCDOT specifications.  Individuals who complete this course will be re-certified to perform HMA Level 1 QC Technician duties on 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.  The participants are also responsible for performing mathematical calculations related to working as a HMA Quality Control Technician. The instructors for the courses are made up of knowledgeable asphalt industry consultants, academia, contractors and SCDOT representatives. 

Course Outline:
To become re-certified, participants must attend a two (2) day course and pass a written exam with a score of 80% or higher.  The exam is open notes and open book.  Topics covered include:

Frequency of Re-certification:
The certification period is five years. It is the responsibility of the individual to keep track of his/her certification expiration date. 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.

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.
