Materials Testing: Reducing Aggregate Samples
Pavements and Materials
Web-based Training (WBT)
$25 Per Participant
TRAINING LEVEL: Basic
CLASS SIZE: Minimum: 1 Maximum: 1
The Materials Testing and Reducing Aggregate Samples course will cover the two methods for splitting a sample; using a mechanical splitter and quartering. The purpose of these procedures is to reduce large samples of aggregate to the appropriate size for testing. The end product should be a sample that is representative of the source.
The American Association of State Highway and Transportation Officials or AASHTO procedures and specifications are used throughout the course. The course covers two methods used for splitting, the mechanical method and the quartering method. Both of these processes are covered in detail. There are questions for the students as a review of the material. References are given for further information.
Upon completion of the course, participants will be able to:
Define aggregate reducing
Describe the aggregate reducing method using mechanical splitter
Describe the aggregate reducing method using quartering
This training is targeted to the beginning technician that will be reducing samples for testing using mechanical spitting and/or quartering for a contractor, producer, agency, or consultant. This training is recommended for the Transportation Curriculum Coordination Council levels I and II.
