Coarse Aggregate Level 2 Testing Technician Re-Certification
The Coarse Aggregate (CA) Level 2 Testing Technician's Certification Course is intended to assure competency in physical property testing of course aggregate materials. Individuals who complete the course will be re-certified to perform CA Level 2 Testing Technician duties for aggregate materials produced for use 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 instructors for the course are made up of knowledgeable aggregate industry and SCDOT representatives.
To become re-certified, 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
- Current Coarse Aggregate Level 1 Sampling and Grading Technician Certification
- Current Coarse Aggregate Level 2 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.
Electronic versions of the course materials are available below. However, course materials can be updated at any time, and these electronic materials may not be the most updated version. The most updated version of the course materials are mailed to all course registrants upon submission of all required registration items and payment.
Section 1 - Important Properties of Aggregate
Section 2 - Flat and Elongated
Section 3 - L.A. Abrasion
Section 4 - Sodium Sulfate Soundness
Section 5 - Specific Gravity and Absorption
Section 6 - Unit Weight
Section 7 - Sand Equivalency
Section 8 - Micro-Deval
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, passing the written exam with a score of 80% or higher, and individually demonstrating proficiency in the four required testing procedures.
