Performance Checklist:
Sampling of Aggregates:
Flowing Aggregate Stream (Bins or Belt Discharge)
5 steps - correct answer - 1. Use a device that will hold the required
amount of material without overflowing.
2. Take each increment from the entire cross section of the material
discharge stream
3. Obtain a minimum of three approximately equal increments.
4. Combine the increments to form a field sample.
5. Ensure that the size of the field sample equals or exceeds the
approximate minimum mass needed or stated in Table 1.

Sampling of Aggregates:
Conveyor Belt
7 Steps - correct answer - 1. Stop the conveyor belt and insert two
templates conforming to the shape of the belt into the aggregate steam.
2. Space the templates so the material between will yield an increment of
the required mass.
3. Carefully scoop the material between the templates into a suitable
container.
4. Collect the fines with a brush and dust pan and add to the container.
5. Obtain a minimum of three approximately equal increments.
6. Combine the increments to form a field sample.
7. Ensure that the size of the field sample equals or exceeds the
approximate minimum mass needed or stated in Table 1.

Sampling of Aggregates:
Stockpiles (Manual Sampling)
7 Steps - correct answer - Course Aggregate
1. Shove a board vertically into the pile just above the sampling point.
2. Take increments from the top third, mid-point, and bottom third of the
volume of the pile.
Fine Aggregate
3. Remove the outer layer and sample from the material beneath.
4. Insert the appropriate sampling tube randomly to extract the increments.
5. Obtain a minimum of five increments.
Coarse and Fine Aggregate
6. Combine the increments to form a field sample.
7. Ensure that the size of the field sample equals or exceeds the
approximate minimum mass needed or stated in Table 1.
