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 or rippability of earth materials is evaluated typically by a geophysicist, engineering geologist, or geotechnical engineer.
