HMA Sampling Certification for Local Agency Projects
This HMA Sampling Course discusses the requirements of the new MDOT Special Provision for Acceptance of Hot Mix Asphalt on Local Agency Projects (12SP-501J-03). All of the new requirements in this special provision will be discussed in detail with particular emphasis on proper HMA sampling procedures meeting the requirements of this new special provision. This training course will “qualify” contractors, technicians, inspectors, consultants, and local agencies to obtain a representative sample of HMA that will yield reliable laboratory test results for acceptance of HMA mixture on Local Agency Projects. Technicians will be required to complete a written exam, 70% minimum, and a practical exam in the field or laboratory demonstrating their ability to obtain a representative sample of HMA.
This HMA Sampling Certification is effective for four years.
Technicians successfully completing the HMA Level One Laboratory Technician Certification Class (aka Bit Level One) at the Ferris Construction Institute in 2015 or later, will be “qualified” to sample hot mix on Local Agency projects.
Hot Mix Asphalt (HMA) Level One Certification and Training
This four-day course is designed for the technician inspecting bituminous mix for roadways on local government agency projects that are not using Contractor Quality Control/Quality Assurance specifications.
The Michigan Department of Transportation regulations require that public or private entities involved in road construction projects on the National Highway System roads which are not QC/QA projects must have a “Michigan Certified HMA Laboratory Technician Level 1” conduct the acceptance tests.
An applicant must be a Michigan Certified Aggregate Technician Level 1 before enrolling in this course. A simple calculator able to compute basic math functions should be brought to class.
The Board of Examiners shall administer the examination for certification. The examination is composed of two parts:
Part 1 - Written examination
The written exam is an open book exam that tests for a basic knowledge of the characteristics of bituminous materials, bituminous plant operations, the calculations required for testing and documentation, and methods used for testing HMA Material
Part 2 - Practical examination
The HMA lab technician must demonstrate proper test procedures to complete:
- Sampling of HMA mixtures and reducing samples for testing
- The Determination of asphalt content by vacuum extraction methods with calculations and reports
- The Theoretical Maximum Density Test with calculations and reports
- The Marshall Bulk Specific Gravity Test with calculations and reports
- Calculate volumetric properties, Pb, VMA, VFA, Va.
Applicants failing any part of the exam will be allowed to retake that portion of the exam, written or practical. However, if an applicant fails a second time, the entire course will need to be repeated. Options for retaking exams will be explained at the notification of failure.
All retests must be completed within thirty days and participants will be responsible to pay $150 for a written retest and $350 for a practical re-test.
This technician training course is a four-day course. This course is designed to give candidates the skills and knowledge necessary to pass the Michigan Certified HMA Laboratory Technician Level 1 Test. The course is composed of both classroom and laboratory instruction, with over half the course devoted to developing laboratory testing skills. Students can expect homework assignments.
Cost: $975.00 each session
Recertification is required every four years. It is the responsibility of the practicing technician to maintain an active certification. For recertification, the technician must pass a written and practical examination, similar in format to the original certification test. Failure to achieve a passing score will require the candidate to retake the exam. Failure to pass the second time will require the candidate to attend the entire certification course. If a Michigan Certified HMA Laboratory Technician Level 1 fails to become recertified within one calendar year from the date of certificate expiration, at a minimum, the full training course must be taken.
The refresher course includes a one-day workshop and written examination followed on the second day by the practical examination described above. The refresher course does not allow sufficient time for the technician to practice test methods. If a technician has not been performing test methods on a regular basis, the technician should enroll in the entire four-day training course. The four-day course does allow sufficient time for technicians to practice current test methods before completing the practical examination.
