12. Refer to Figure II-1 attached. A flexible pavement is to be evaluated according to the AASHTO 1972  design guide. The existing pavement has a weighted structural number=3.4, a regional factor=2.0, and a  soil support value=4.5. What would be the approximated number of daily equivalent 18-kip axles to be  allowed on this road for a 20-year analysis period? a. 10 b. 33 c. 100 d. 1490
