History of AASHTO Rail (Impact/collision) load?
(OP)
AASHTO 2.7.1.3: Is anyone familiar with where the requirement of 10 kip rail (impact) load came from? I am investigating an 8" concrete slab overhang on a bridge as per AASHTO 3.24.5.2. Is this load crash test related(?) not truck related? Is this good for HS20 & HS25 type trucks?

If your interested, check out NCHRP Report 350 "Recommended Procedures for the Safety Performance Evaluation of Highway Features" which includes barrier rails.
Good Luck.
