Rock young modulus

Web13 Feb 2001 · As a general rule, if completely granular and poorly graded, somewhere between 10,000 psi and 25,000 psi. If slightly cohesive or well graded, then values may go from around 25,000 psi to over 100,000 psi. To give you a "measuring stick", a good, granular pavement base material will typically be somewhere around 50,000 to 70,000 psi. Ron. WebRock Mechanics - University of Notre Dame
