Is Gypsum Rippable?
(OP)
We have a large quantity of gypsum that needs to be removed for a roadway. Due to velocities over 16,000 fps, it will be classified as rock exc. However, it seems gypsum would be easily rippable. Has anyone had any experience with that?

16,000 ft/sec sounds pretty high for gypsum. Is the gypsum hosted in another rock type?

Which brings up another point. Our geotech says we can't use the gypsum as roadway fill. I know it should not be used with lime treatment, but other than that, as long as it's covered with a non-dispersive layer, why not?

You may be able to excavate with high-pressure water.
I don't have any experience or knowledge of anybody actually doing it though.
