Aggregate Production Tester Certification
The Aggregate Production Tester Certification (APTC) is required for anyone who performs Quality Control (QC), Quality Assurance (QA), or Independent Assurance (IA) sampling and testing of aggregate (rocks). This includes procedures such as aggregate sampling, sample reduction, sieve analysis, and loss by washing. (See course objectives for a complete and detailed list of test procedures.)
People who have and use this certification work at/for MnDOT (in QC, QA, and IA roles), local agencies (counties and cities), consultants, contractors (the private businesses who are contracted to do construction work), and producers (businesses that supply the aggregate materials, including concrete and bituminous plants).
This introductory course focuses on fundamental information about aggregate materials (rocks, sand, and gravel) and the key methods used to sample, conduct test procedures, and document test results to ensure these materials meet roadway and bridge construction quality requirements.
Instruction includes lecture, demonstration, discussion, practice activities, and hands-on lab experiences with the testing procedures. Quizzes, course resources, and content reviews are included to help participants prepare for the written and lab-based performance exams. Depending on participants’ prior knowledge and experience, they may want to do additional practice and review before taking the class and/or the exam.
