HMA Level 1 Quality Control Technician



Course Description:
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 certified to perform HMA Level 1 QC Technician duties on SCDOT projects.  Each participant is responsible for performing laboratory quality control tests during the course, demonstrating competency of these testing procedures individually, and performing mathematical calculations related to working as a HMA Level 1 QC Technician.  The instructors for the courses are made up of knowledgeable asphalt industry consultants, academia, contractors and SCDOT representatives. 

Course Outline:
To become certified, participants are required to attend a three-and-a-half (3 ½) day course, pass a written exam (open book and open notes) with a score of 80% or higher, individually demonstrate proficiency in quartering of HMA (closed book and closed notes), and pass an individual oral exam (closed book and closed notes) on each of the following laboratory procedures:

  • Aggregate Stockpile Sampling
  • Dry Sieve Analysis
  • Washed Sieve Analysis
  • Compacting Laboratory HMA Samples
  • Ignition Oven (including correction factor)
  • Maximum Specific Gravity (MSG)
  • Bulk Specific Gravity (BSG)
  • Indirect Tensile Strength (including compaction and testing)
  • Stability (including compaction and testing)

 Participants must score 80% or higher on the oral exam for each laboratory procedure as well as on the individual demonstration of HMA quartering.   

The course is divided into two parts - a lecture portion and a laboratory portion.  During the laboratory session, the class is divided into subgroups of three or four students.  The groups work together as teammates to perform laboratory procedures simulating actual working conditions at the asphalt plant.  After performing the procedures in the lab as a group, the students are required to prove their own individual capabilities on the last day of class with an individual demonstration of the HMA quartering procedure and individual oral exams on the remaining laboratory procedures.  Topics covered include:

  • Technician's Responsibilities
  • Materials
    • Aggregate
    • Asphalt Binder
  • SCDOT Laboratory Procedures and Related Calculations
    • Dry Sieve Analysis
    • Washed Sieve Analysis
    • Ignition Oven
    • Maximum Specific Gravity
    • Compacting Laboratory Samples
    • Bulk Specific Gravity
    • Calculation of Volumetric Properties
    • Indirect Tensile Strength
    • Stability
  • Overview of Mix Design
  • SCDOT Specifications

Entry Requirements/What to Expect:


  • Experience form signed by either a certified HMA Level 3 QC Manager or a certified HMA Level 1 QC Technician confirming 6 months of related asphalt lab experience

Additional Prerequisites for SCDOT Participants Only

Re-certification Requirements:
To become re-certified, the participant must attend a two (2) day course and pass a written exam (open book and open notes) with a score of 80% or higher.  The re-certification course will contain a general overview, a review of all specification changes, and any procedural changes that may have occurred.

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.
