HL93 LRFD Bridge Design Loading
HL93 LRFD Bridge Design Loading
(OP)
AASHTO specs out a 0.64klf lane loading for a ten foot width and a single design truck to be applied in a simple span bridge. Does the number of design trucks that are applied to the span change depending on the span?
If it does what is the spacing between them?
References to AASHTO would be appreciated, or other published material

Note that this is in each lane, modified as appropriate with the Multiple Presence Factor, positioned to give the greatest live load effect.
(By the way, I was CalPoly '91)
