40' Of Shale | Heavy Equipment Forums

Jan 13, 2021· Hey there, I'm currently bidding on a job in Colorado. We'll be removing material to a depth of around 60'. 40' of that is shale. 800' (L)x600' (W)x60' (D) The GC thinks we may have to blast. I'm thinking we'll be able to rip through it with a D8 or D9 and then haul it out with 745 haul trucks and a 349 hoe. The top 20' we'll remove with scrapers.

Cyclic loading tests on sandstone and limestone shale ...

Jun 01, 2009· Over 4 × 10 3 loading cycles, at the 500 kPa pressure, the resilient deflections rose from 1.0 to 1.5 mm. In Tests 3 and 4, 250-mm-deep and 400-mm-deep limestone shale produced maximum resilient deflections of 1.0 mm at an applied pressure of 500 kPa. In both tests, loading was suspended due to high permanent deformations.

Uniaxial Compressive Strength - an overview ...

The uniaxial compressive strength of a rock under static loading often decreases with an increasing temperature at which the rock has been heat-treated before strength testing. This conclusion is drawn from a great number of experiments [1,2,4,8,9,11,17–19].The higher the temperature is, the lower the strength. Some results for uniaxial compressive strength σ c …
