4. Bulk Density Test The bulk density measurement should be performed at the soil surface and/or in a compacted zone (plow pan, etc.) if one is present . Measure bulk density near (between 1 and 2 feet) the site of the respiration and infiltration tests. To get a more representative bulk density measurement of the area, additional samples may
The bulk density of the powder is measured using a cylinder of known volume placed under the dry flow test funnel as shown in Figure 18.7.The powder is leveled off after filling the cylinder (taking care not to tamp it and cause settling) and weighed. The weight of the powder is then divided by the volume of the cylinder to calculate bulk density.
1.1 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.
