About the Course

This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.

The course can be completed in about one hour.

Learning Outcomes

By the end of this course, you will be able to:

• Determine specifications for balance, tamping rod, measure, and shovel or scoop

• Identify equipment for measuring volume of measure

• Recognize preparation process for test samples

• Recall procedures for determining volume of measure

• Identify methods A-Rodding, B-Jigging, and C- Shoveling for determining compacted bulk density of aggregates

• Recall equations for calculating bulk density, void content, and volume of measure

• Define the symbols utilized in equations for calculating bulk density, void content, and volume of measure
