If I know the California bearing ratio for my subgrade and am able to calculate a structure number, is there a reason to also know the soil support value?

CBR and SSV do not correlate exactly. If you are happy with the SN you have developed, no reason to use SSV.

RE: Pavement Structure Design
I am a rookie in pavement design and at this time do not have access to AASHTO Guide for Design of Pavement Structures. The particular guidelines and requirments I have to use for are based on AASHTO. The guidelines are clear enough to do a cookbook method of designing the pavement structure which involves a simple DOS program to calculate SN given the ADT, CBR, %trucks, and some other assumed values. A standard table documenting the pavement structure thicknesses and relevant input must be included in the contract plans. The skeleton table also wants the SSV even though it was not used in the calculation or as far as I can tell has anything to do with the design. I am also trying to contact the district engineer to get answers but I thought I would give this forum a try for the first time.
Thanks
Could you point me in the right direction for calculating the SSV?
