Subject: LRFD and AASHTO
I am a recent graduate and would typically use LRFD in designing.  My boss typically uses ASD.  I am just doing simple sign structures for DFW Airport but the question has come up, how does LRFD fit in with AASHTO?  Specifically we are looking at the different load combinations and which factors to apply.  If anybody has any ideas please respond directly to me.
