MDOT TRAINING AND CERTIFICATION


Certification Requirements
The Michigan Department of Transportation (MDOT) Density Control and Inspection Manual states that technicians conducting field density tests on MDOT projects must be certified and maintain their certification through a program conducted or approved by the MDOT Geotechnical Services Section, Density Technology Unit. The Density Control Training and Certification program offered by Lawrence Technological University (LTU) and taught by MDOT staff is designed to meet the needs of transportation technicians and their supervisors to acquire and/or maintain this required certification.

Lawrence Technological University
The training courses will be held in Lawrence Tech’s new Transportation Materials Laboratory with state-of-the-art equipment. Conveniently located in Southfield, LTU’s modern campus is easily accessed by freeway and offers plenty of free parking. Lunch can be purchased at the University’s all-you-care to eat cafeteria with multiple food stations. All classes are held 8.30 a.m.–4.30 p.m. daily.

MDOT Density Control Training
The Course
The four-day course consists of three days of instruction and hands-on laboratory training and one day of testing. Course topics include:

1. Introduction to compaction and density testing
2. Density Tests

     a. The One-Point T-99 Test
     b. The AASHTO T-99 Test
     c. The One-Point Michigan Cone Test
     d. The Michigan Cone Test
     e. The Michigan Modified T-180 Test
     f. The In-Place Density (Nuclear) Test
     g. Speedy Moisture Test

3. Documentation Requirement

THE EXAMINATION
Participants must successfully complete both the written and practical parts of the examination to receive the MDOT Density Control Certification.

Part 1 – Written Portion
The open-book examination consists of multiple choice questions covering the fundamentals of density control on soil subgrade, aggregate bases, and asphalt materials. Basic mathematical skills, such as use of fractions, decimals, ratios, and percentages, are required.

Part 2 – Practical Portion
The exam requires participants to give verbal descriptions of field tests and demonstrate competency in performing the Michigan Cone, One-Point T-99, T-180, Speedy Moisture, and In-Place Density (Nuclear) tests.

MDOT Density Control Recertification
Recertification is required every three to five years depending upon the initial training. LTU also offers recertification courses. The two-day course consists of a one-day refresher workshop and an exam day. The recertification exam has written and practical sections similar to the certification exam.

PROGRAM SUMMARY - AGGREGATE INSPECTION

Certification Requirements

The Michigan Department of Transportation (MDOT) stipulates that technicians performing aggregate inspection for and on MDOT projects must be certified and maintain their certification through a program conducted or approved by MDOT. The Aggregate Level 1 Training course offered by Lawrence Technological University (LTU) and taught by MDOT staff is designed to meet the needs of transportation technicians and their supervisors to acquire and/or maintain this certification.

The aggregate inspection courses will be held in Lawrence Tech’s new Transportation Materials Laboratory with state-of- the-art equipment. Conveniently located in Southfield, LTU’s modern campus is easily accessible from major freeways and offers plenty of free parking. Lunch can be purchased at several on campus locations, as well as several nearby restaurants. All classes will be held from 8:30 a.m. to 4:30 p.m.

MDOT Level 1 Aggregate Inspection Training
The Course

The three-day course consists of two days of instruction and hands-on laboratory training and one day of examination. Course topics include:

1. Aggregate sampling and stockpiling
2. Sample size and sample reduction
3. Mechanical Analysis
4. Documentation

The course includes instruction, training, and testing for the following standard test methods:

  • AASHTO T-2: Sampling of Aggregates
  • AASHTO T-248: Reducing Samples of Aggregate to Testing Size
  • AASHTO T-11: Materials Finer Than 75-µm (No. 200) Sieve in Mineral Aggregates by Washing
  • AASHTO T-27: Sieve Analysis of Fine and Coarse Aggregate
  • MTM-117: Michigan Test Method for Determining Percentage of Crushed Particles in Aggregates

The Examination

Participants must successfully complete both a written and a practical exam to receive Aggregate Inspection certification.

Part 1 – Written Portion

The examination consists of multiple choice questions covering the fundamentals of aggregate sampling and stockpiling, sample size and sample reduction, and mechanical analysis of aggregate. Basic mathematical skills, including the use of fractions, decimals,ratios, and percentages, are required.

Part 2 – Practical Portion

The exam requires participants to give verbal descriptions of field tests and demonstrate competency in performing all of the test methods listed above.
