<< I am inclined to believe that using the AASHTO code is sort of
counterproductive since many of the assumptions made therein (esp. load
factors) aren't really applicable for a taxiway bridge.
Also, I have tried in vain to find information on the wheel loading pattern
for the Antonov 124 "Ruslan" cargo aircraft, which will be, I believe, the
"big enchilada" governing design of our bridge. >>
In FAA AC 150/5300-13 (change 5) chapter 7 is titled Runway and Taxiway
It is my understanding the antonov 124 is considered heavy lift equipment not
typically rated or approved for flight in US domestic airports. My
recollection is the governing wheel loads most severe on the pavements is the
727-100. The larger aircraft have more tires and spread the load more.

The 24-wheel landing gear system (two nose and ten main wheel bogies, five
per side, each with two wheels) enables the aircraft to operate from
unprepared fields, hard packed snow, and ice-covered swampland. It also has a
"kneeling" capability, but is not nearly as advanced as the C-5's 28-wheel
system. On 26 July 1985, the An-124 set 21 official records by lifting a
payload of 377,473 lbs (171,219kg) to an altitude of 35,269 ft (10,750m).
