Proper Wingwall Design on Culverts
(OP)
I am wondering what the proper technique is for designing a concrete wingwall attachment for a sloped pipe. From what I've seen and read, I have encountered 2 ways. One way is a vertical headwall with the entrance/exit slab being flat, and the other way is a vertical headwall with the entrance/exit slab matching the slope of the pipe. Can anyone give me a good direction? Thanks.

Be careful with vertical headwalls near roads - they are severe roadside hazards. AASHTO recommends that transverse pipes over 3 ft and parallel pipes 2 ft or over have either traversable end sections or guiderail. Traversable ends are preferred.
