DOES ANYONE KNOW THE FORMULA SUITABLE FOR SPREADSHEET USE FOR CALCULATING A PAVEMENT SN (STRUCTURAL NUMBER) KNOWING THE TF (TRAFFIC FACTOR) AND CBR/IBR (CALIFORNIA/ILLINOIS BEARING RATIO?

Use the AASHTO equation and keep it general with flexible input. That way you can design the pavement section based on a variety of input factors, not just CBR or other stability criteria.
