Development/Splice length for reinforced concrete?

For anyone who's done any concrete design/detailing, I've got a question about how you handle a particular situation. I have a simple span box-girder bridge with a composite concrete deck. Traditional deck design (not empirical), 4 layers of reinforcement in the slab. The span length requires that I splice the longitudinal deck bars. Which development/splice provision is appropriate here? Since it is a simple span, the bars aren't tension bars, they're in the compression zone for the member but aren't there for strength, they're really just temperature/shrinkage bars.

更新:

Applicable design code is AASHTO LRFD.

    The code calsl for a minimum overlap of splices regardless of the load on the re-enforced concrete. I don't remember the amount of over lap but it is something like 10 or 20 diameters of the rebar size.

    What kind of engineer are you? You really can't figure this one out? Did you get your degree in some third world country?
