Constrained Modulus of Crushed Rock for Pipeline

The test was performed on different clean, uniform samples of crushed rock. Each sample was tested at low, medium, and high densities. The tests were incrementally loaded to a pressure simulating about 150 feet of fill. The stress-strain curve was found to be linear with load, resulting in a constant value of constrained modulus for each soil at a specific density. The constrained modulus was

Sub-sampling (chemistry) Wikipedia

A riffle box is a box containing a number (between 3 and 12) of "chutes" slotted paths through which particles of the sample may slide. The sample is dropped into the top, and the box produces two equally divided subsamples. Riffle boxes are commonly used in mining to reduce the size of crushed rock samples prior to assaying.
