I already have the correlation between the proctor standard and the modified proctor. If you mail me the proctor curve, I will return you the modified curve, for any kind of material.
I am writing a book about the Proctor test and other laboratories testes. These is part of my researches, and I...
The best formula for this correlation according with my experience is:
K=-3.03E-05(CBR)^4+0.0069(CBR)^3-0.571(CBR)^24.305(CBR)
