AASHTO Wood Reference Design Values (Table 8.4.1.1.4-1)

I'm confused with what "size classification" a 2x10 would be in AASHTO LRFD Table 8.4.1.1.4-1. That table gives different design values (allowable stresses prior to applying various strength factors) for the different size classifications which I listed in the original post.

Almost positive that a 2x10 would be 2" wide (nominal) for AASHTO.

Depends on how the lumber is oriented. "Wide" is the horizontal dimension. "Thick" is the vertical dimension. A 2x10 used as a typical beam is 2" wide.
A 2x10 used as, say, deck flooring is 10" wide.

Take a look at the attached, PS-20, The American Softwood Lumber Standard. I believe this is what AASHTO follows. Also, look at the Commentary to AASHTO 8.4.1.1.1
