should be made to attendees that the successful completion of these courses is critical to their continued careers in materials testing.
A general summary of each course is as follows:
Basic Aggregates. This course focuses on sampling and testing of to be used for base/subbase layers, Portland cement concrete, and hot-mix
asphalt concrete and includes testing for gradation and specific class is a mandatory prerequisite
to each of the Technician training /certification course, but must be completed only once. Those seeking certification in more than one specialty area should take Basic Aggregates immediately prior to their first technician course.
(2) Soils/Aggregate Technician. This course focuses on lab and field tests of soils (with some aggregate applications), and includes classification, lab density, and
This course requires the use of a nuclear density gauge, therefore each
participant must have attended a radiation safety course and provide a personal radiation dosimeter. Failure to do so will result in the person being ineligible for the course.

(e) Training by Central Laboratory. In addition to the above courses, potential Materials Inspectors, in limited numbers, may be temporarily assigned to the Materials Division Central Laboratory for training in specific tests. To accomplish this temporary assignment, the following procedure shall be used:
Inter Office Memorandum to the District Engineer listing the Inspector's names, the background of each, the requested area of training, and the duration of the temporary assignment.
This request will be forwarded to the Construction Office along with the District Engineer's recommendation and a request to pay the expenses of the individuals for the duration of the temporary assignment.
