Class Manual Revision

Manual Release, January 2016


​Initial Qualification:

  • Pass Earthwork Level 1 Written exam

  • Pass Earthwork Level 1 Proficiency exam

  • Valid Nuclear Radiation Safety Certificate

Recommended Training Course, APNGA (American Portable Nuclear Gauge Association),


  • Pass Earthwork Level 1 Written exam

  • Valid Nuclear Radiation Safety Certificate.

  • Written Exam Required

  • Proficiency Exam Required.

  • Closed Book Exam.

  • Allowed up to 2 Hours to complete the Written Exam.

  • Allowing your Level 1 Qualification to expire, will require passing both the Level 1 Written & Proficiency Exams. Prior to your expiration date, only the Written exam is required for re-qualification.

Proficiency Exam Details:

The Trainee must demonstrate proficiency in nuclear testing (FM 1-T 238) and moisture content (FM 5-507) and report the test results in an FDOT Density Log Book. The Trainee has two opportunities to successfully demonstrate all items on their checklist. Two failures in one area will constitute failure of the proficiency examination.

Subject Matter:

  • Moisture Density Relationship (FM 5-521 and 5-525)

  • Density of Solid and Bituminous Concrete Mixtures in Place by the Nuclear Method (FM 1-T 238)

  • Determination of Moisture Content by Means of a Calcium Carbide Gas Pressure Moisture Tester (FM 5-507)

  • Reporting Test Results in the FDOT Density Log Book, Sampling Soils, Limerock, Cemented Coquina, Bank Run Shell, and Stabilizing Materials from the Roadway (FM 5-504)

  • Nuclear Gauge Maintenance

  • Sampling Soils and Limerock.

Class Objective:

To safely and effectively sample soil materials from the roadway, take earthwork density readings and record those findings in an FDOT Density Log Book.

Students are able to attend the Level 2 class without waiting for their grades to be posted on their Level 1 exams. Worst case scenario: successful completion of Level 2 and a failed level 1. The Level 2 certification will be in pending status until the student successfully completes Level 1.

A&SW purposely schedules all Level 2 classes immediately following the Level 1 classes for the benefit of our students. Some students find it beneficial to take the classes and exams subsequently, since they are already in class and the information is fresh. When recertification comes around, this is convenient to some students since both expiration dates will be within a couple days of each other.

The Earthwork Level 2 class covers Density Theory, Density Log Books, and the Overview of FDOT Standard Specifications and Design Standards.
