- Excavatability
The excavatability of an earth (rock and
regolith ) material is a measure of the material to be excavated (dug) with conventional excavation equipment such as a bulldozer with rippers, backhoe, scraper and other grading equipment. Materials that cannot be excavated with conventional excavation equipment are said to be non-rippable . Such material typically requires pre-blasting or use of percussion hammers or chisels to facilitate excavation. The excavatability orrippability of earth materials is evaluated typically by an engineeringgeophysicist orgeotechnical engineer , often in conjunction with aseismic refraction survey.
