Hello,
You must first go into your alignment properties by selecting the alignment, right-click, alignment properties. Then you want to select the design speeds tab and assign a design speed to your alignment. Next select the Superelevation tab, set your superelevations properties using the icons in the top left and from there you may select the AASHTO 2001 speed table.
Good luck,
