Coarse Aggregate Level 2 Technician

The Coarse Aggregate (CA) Level 2 Testing Technician's Certification Course is intended to assure competency in physical property testing of course aggregate materials.  It is aimed at aggregate suppliers' QC/QA technicians and appropriate SCDOT personnel who are required to perform and regulate necessary aggregate QC/QA tests.  Individuals who complete this course will be certified to perform CA Level 2 Testing Technician duties for aggregate materials produced for use on SCDOT projects.  The instructors for the course are made up of knowledgeable aggregate industry and SCDOT representatives.

Course Outline:
Participants are required to attend a one-and-a-half (1 ½) day course, pass a written exam (open book and open notes) with a score of 80% or higher, and individually demonstrate proficiency (closed book and closed notes) in each of the following required laboratory testing procedures:

  • Specific Gravity and Absorption of Coarse Aggregate (AASHTO T 85)
  • Resistance to Degradation of Small-Size Coarse Aggregate by Abrasion and Impact in the Los Angeles Machine (AASHTO T 96)
  • Plastic Fines in Graded Aggregate and Soils by Use of the Sand Equivalent Test (AASHTO T 176)
  • Method for Determining Flat and Elongated Particles in Coarse Aggregate (SC T 77)

Upon registration AND payment for the course, each participant will be sent a course manual. 

Topics covered in the course include:

  • Important Properties of Aggregates
  • Flat and Elongated Particles
  • Los Angeles Abrasion
  • Sodium Sulfate Soundness
  • Absorption and Specific Gravity
  • Sand Equivalency

Entry Requirements/What to Expect:
All participants in this course are expected to have some laboratory experience in testing aggregate and should be familiar with the related SCDOT specifications.


  • Current Coarse Aggregate Level 1 Sampling and Grading Technician Certification 

Additional Registration Information:
If registration information and payment for the course are not received at least 14 days prior to the course start date, the participant will not receive a course manual and will be dropped from the course.  If the registrant provides an incorrect mailing address and the manual has to be re-shipped, a $10.00 processing and handling fee will be charged.
