Can we use in-situ Schmidt Rebound Value for calculation of JCS ?

I have in-situ SRV of Joint, can we use this value (in-situ Schmidt Rebound Value) for calculation of JCS ? Is SRV scale dependent or not? If yes! would you recommend a paper? Thank you

Why does the upper block become more rougher than previous roughness, after test, during a direct shear test of natural rock joints?

I am working on roughness influence on shear strength of rock. I am facing problems regarding roughness of the upper block as I asked in the question. I am looking forward to the answer.
