MnDOT Technical Certification
In light of the recent COVID-19 precautions, MnDOT has suspended all classes for the remainder of the training season. Your registrations will be cancelled and you will be refunded your full class fee. Please be patient as LSC works through the high volume of cancellations and refunds. We are doing our best to work quickly and efficiently during this uncertain time. MnDOT is also coming up with a plan to for those who need to recertify their classes yet this spring. You will be notified once a plan has been implemented. Our online classes will stay open until April 30th - please consider taking one of our online recertification classes if you need to recertify in: Bit Plant 1, Concrete Field 1, Bituminous Street, Grading and Base 1, or Grading and Base 2. In the meantime, practice social distancing, personal hand washing hygiene and stay safe.
Aggregate Production * Bituminous Plant
Bituminous Street * Bridge Construction
Concrete Field * Concrete Plant
Concrete Strength Testing * Grading & Base
This is a three day introductory course taught both in the classroom and in the lab. It covers aspects of aggregate production and quality control testing. Subjects include: prospecting for aggregate, crushing and stockpiling, aggregate blending, process control, and effects of non-complying aggregate on construction. Test topics include aggregate sampling, splitting, gradations, aggregate specific gravity, moisture, spall identification, percent crushing, and other aggregate durability and quality tests. This course includes a hands-on performance review. This is done during the lab.
There is currently no level 2 or recertification course for aggregate production.
Options include Bituminous Plant 1 and 2.
Recertification for all is available in a classroom setting.
Subjects to be covered are the following test procedures: Maximum Specific gravity (Rice Test), Air voids, and bulk specific gravity as determined from Marshall specimens demo and explanation of Gyratory specimens and compacted pavement cores, extraction and gradation of salvaged-asphaltic aggregate (RAP), and the Tensile Strength Ratio (TSR-Lottman) test.
Bituminous Mix Design requirements and working ranges specified by MnDOT specifications. It also covers subjects such as blending aggregates and recycled mixture design. There will be a day of lab work as well as four days in the classroom. This course prepares the student for doing MnDOT Trial Mix Design submittals.
Topics include: asphalt properties and types, production and testing, plant types and operation, aggregates used in production of hot-mix design concepts, paving and compaction specifications, inspector and contractor roles, MnDOT QM Specifications and certified plant requirements.
Choose from Concrete Field 1 Concrete Field 2 or Concrete Field 1&2 Recertification. There is an online/e-learning recertification available for CF1.
The test procedures presented include slump, strength, air contents, unit weight, and sampling.
Also covers materials technology and construction practices based on MnDOT specifications and PCA publications.
UPDATE - Concrete Field 1
ARM will be conducting several Concrete Field 1 sessions, the first of which will be April 23-24. These sessions will be conducted in larger classrooms and/or with smaller class sizes in order to provide 6 feet spacing between students. For the performance exams, students will be assigned an exam time. Exam times will allow for one student and one proctor at each testing station, and will allow for 6’ spacing. Most classes will be limited to 15 students in order for ARM to meet federal guidelines. Exam dates and registration links are listed below. Please note that the COVID-19 situation is changing almost by the hour, which means that all sessions are subject to change at any time.
April 23-24: ACI Concrete Field Testing Tech Level 1, Bloomington
May 4-5: ACI Concrete Field Testing Tech Level 1, Eagan
May 6-7: ACI Concrete Field Testing Tech Level 1, Eagan
Options include Grading and Base 1 and Grading and Base 2. Recertification is available in a classroom setting or online.
Courses cover soil identification, the moisture-density test (proctor) field moisture and density determinations, and the Dynamic Cone Penetrometer test procedure.
Some courses discuss the inspector's roles and responsibilities, sub-grade soils and soils identification, excavation and embankment construction, base construction, turf establishment, geosynthethic applications and compliance with labor laws.
