NHI Course 131136 – TCCC Materials Testing: Reducing Aggregate Samples (Web-based Training)


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.
