I need to know if there is a correlation, a formula or any method to determine the modulus of subgrade reaction using the DCP index or CBR values. I want to evaluate de CBR and modulus of subgrade reation of sois using only DCP index, for airfield pavement evaluation.
Thank you for your replies
I need to know if there is a correlatión between SPT(Standard Penetration test), CBR(California Bearing Ratio) and DCP(Dynamic Cone Penetrometer). If tyou know something about this subject please let me know.
Thanks,
Daniel Denis
