Integral Abutment on Spread Footings
Integral Abutment on Spread Footings
(OP)
Has anyone had experience with integral abutments on spread footings? I found two DOTs that describe the use; Maine Dot and Nevada DOT. I could only find details on Nevada DOT. I am looking at using, but trying to do a little more research and finding little information. Thanks for any help.

The design and details are very similar for both spread footing or piles. Most countries in Europe are allowing spread footings and I'm seeing no reason for not doing it in US.
For longer bridge (over 200 ft) you may consider using hinged abutment at one end (with Freyssinet type semi-plastic concrete joint), but rigorous analyses with good software and adequately modeled soil springs could be helpful.
