MnDOT Technical Certification

Aggregate Production * Bituminous Plant
Bituminous Street * Bridge Construction
Concrete Field * Concrete Plant
Concrete Strength Testing * Grading & Base


A Mn/DOT Tech ID# is REQUIRED to register for certification courses. If you do not have an ID#, please click on:  MnDOT Tech ID.

Registrations will be processed on a first come-first served basis. The class sizes are limited, so early registrations are suggested to obtain the date preferred. All online registrations must be paid with a credit card or the PO option (Organization accounts only).

REGISTRATIONS WILL NOT BE PROCESSED WITHOUT PAYMENT unless you are an organization account and get PO permission.

Reminder:  Lunch is on your own for all MnDOT classes.


Aggregate Production
This is an introductory course taught both in the classroom/virtually and in the lab. There will be one day of classroom instruction (in person or virtually) and one scheduled time slot for the lab portion. 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 Bituminous Plant 2. Recertification is also available for levels 1 & 2.
All Bituminous Plant courses will be held 100% live online, Bit Plant 1 will also have a hands on performance review in the field TBD.

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.

Options are Bituminous Street and Recertification.
All Bituminous Street courses will be held 100% live online.

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.

Courses offered are Bridge Construction and Bridge Construction Recertification. 

Bridge Construction is an advanced two week course designed for Bridge Construction Inspectors. Students receive instruction in bridge staking, excavation and embankment, foundations, steel reinforcement, sub structures, structural steel, forms and false work, pre-stressed beams, deck expansion joints, superstructures, deck drainage, bridge utilities, deck wearing courses, timber bridges, special structures, slope protection, documentation, approach panels, reconstruction, widening, and safety practices. This course is recommended for those involved in any type of structural construction. This is the only Bridge Construction Inspection course.

Prerequisite: Aggregate Production, Concrete Field 1 & 2, Grading and Base 1.  
 The following AASHTO eLearning is also required:

The following AASHTO eLearning is strongly recommended: Register for AASHTO Prerequisite Classes

Choose from Concrete Field 1, Concrete Field 2, or Concrete Field 1 & 2 Recertification. 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.

Concrete Field 1: ACI: One day of classroom instruction either in person or virtually and one block of in person lab instruction.

Concrete Field 2: Two days of virtual classroom instruction via GoTo Meetings.

Concrete Field 1 & 2 Recert: One day of virtual classroom instruction via GoTo Meetings.
*If you need to recertify your CF1-ACI, you must retake the FULL CF1-ACI class.


Concrete Plant 1 and Concrete Plant 1 Recertification is available. 

*Level 2 was eliminated when MnDOT switched from MnDOT Mixes to Contractor Mix Designs for concrete in 2016.

The instruction covers the sampling and gradation of aggregates as well as moisture determinations and batch adjustments.
Also, some courses will relate specific performance requirements to the concrete mix design and production controls to produce the specified mixes and covers ACI mix design procedures and specific MnDOT requirements as well as aggregate and admixture technology.

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.
