This is the new I-43 north to I-41 south flyover ramp that has a polymer anti-skid coating applied to the bridge deck. On the AA Roads facebook page someone thought that it was asphalt but it is polymer. I'm guessing that it isn't very common yet so I was wondering which other states or cities are applying this to some of their bridge decks?
I believe it's been applied in Upstate New York in a few locations (I believe NYSDOT Region 3 did on some bridge north of Syracuse quite recently).
It may also have something to do with winter as well, INDOT is putting a special deck overlay that has a lower freezing point, to help with keeping the road from freezing so easily.
Can anyone point out a specific product with SDS/MSDS? All I can find so far is basically a sand in some adhesive, which makes road more textured (better grip, more rubber wear).
Pre-salting roads before winter weather is a completely different story...
I've seen similar applications throughout Somerset County, NJ, this for example: https://www.google.com/maps/@40.5828672,-74.5572491,3a,82.2y,11.82h,72.96t/data=!3m6!1e1!3m4!1sYkKYqPaNu-7G3Y1k1vHT7A!2e0!7i13312!8i6656
At least what they did above is much much better than what they did to curtail a similar problem on roads in Hillsborough: Repave the road and partially mill it: http://patch.com/new-jersey/hillsborough/road-project-leaves-rough-surface

Anywhere in Region 5? This is new to me...

I doubt it. I'm not an engineer, but all I know is that when the MO heard that Region 3 was going this route on a couple of their bridges, there were some engineers in NYSDOT's Structures group that raised their eyebrows. Have no idea what the specific concerns were other than "bang for the buck" types of issues.
Noticed that the I-94 Mississippi River Bridge in Minneapolis just received a coating
PA is applying a latex overlay on many of it's bridges...and pretty widespread. I read where the main benefit is a way to seal and preserve the concrete deck, and the anti-skid properties are a nice bonus.
I think NY region 6 may be doing that (or have done that) as well in a couple of places on I-86 near Bath and I-99.
The just did this to the Neuse River Bridge and the Freedom Memorial Bridge here in New Bern. If feels and sounds weird, but I can attest to the extra grip when it rains. I almost can't wait for the winter to get here to see how it stands up to that first ice storm.
I've heard of something being spray-applied to a flyover ramp at the 135/54 interchange in Wichita. Any Kansas users know about that?
