Load-bearing Capacity Test
Effective Mar 7, 198610 Ill. Reg. 4864AUTHORITY: Implementing Sections 22(g), 22.4(b) and 22.6 and authorized by Sections 22.6 and 27 39(h) of the Environmental Protection Act (Ill. Rev.

- a) Apparatus: Soil penetrometer with a range of 0 to 4.5 tons per square foot
b) Procedure
- 1) Collect a representative sample of the treatment residual. If the material is a monolithic solid proceed to step (2). If the material is granular it should be compacted.
- 2) Grasp the penetrometer by the handle and push the point into the sample by hand, at a constant rate, up to the calibration mark.
- 3) Read the unconfined compressive strength on the low-load side of the indicator ring.
- 4) Return indicator ring to initial position for the next test.
- 5) Repeat the test at least 3 times and average the result.
