Mechanical property testing is underway on all eight ARPA rock types. A manuscript for reporting the test results is underway. A comprehensive listing of rock property data obtained from Bureau of Mines and outside literature review on rock classification for engineering purposes has been completed, and development of a qualitative rock classification system is underway.
