Course Overview
Details the procedures used to obtain representative samples for testing. Testing procedures (including selection and preparation of equipment), performance, record keeping and result analysis for sieve analysis, specific gravity, absorption, abrasion, chemical soundness and petrographic analysis are covered. Access to a laboratory will be required to demonstrate competency in testing procedures.

Learning Outcomes
Upon successful completion, the student will be able to:
Module 1 - Aggregate Sampling and Test Preparation
- Describe the procedure for extracting representative samples of aggregates from conveyors, stockpiles, trucks, barges, bins and pit faces in accordance with recommended practices and using common sampling techniques.
- Determine the size of sample required for any test to be performed on the aggregate.
- Identify the source of the sample by using correct labeling procedures.
- Prepare sampled material for designated aggregate tests by splitting and using other recognized methods.
Module 2 - Grain Size Analysis
- Perform a mechanical separation by particle size of a representative sample of coarse or fine aggregate.
- Calculate and plot the grain size distribution of an aggregate sample.
- Perform a wash test on an aggregate sample.
Module 3 - Relative Density
- Describe and perform the procedure for obtaining the relative density test on fine and coarse aggregates.
- Calculate the bulk density, the bulk SSD density, the apparent density and the absorption for an aggregate sample.
- Assess the test results and recommend or reject the aggregate for use on a specified project.
