Back in college I interned in a public works department. Part of the job of the interns was to drive around the village streets rating pavement and then using a special GIS linked program with some formulas for overall pavement quality. The results would be color coded and presented at village meetings to determine which streets would get repaved. In the hours spent rating pavement we came up with the following nicknames:
Cookie - for raveling (losing the top layer of asphalt) since cookies crumble
Pirate - for large patched sections
Squirrel - small patched sections
Zebra-lateral cracking (perpendicular to the direction of road)
Giraffe-longitudinal cracking (along the length of the road)
Momma, pappa, and baby gaitor cracks
Canyon - sink holes (deep holes around sewer lines indicating poor backfill)
Rollercoaster - rutting
These seemed much more cleaver in college.
I see a lot of the shallow moon-craters lately. These are where the topmost repaving layer delaminates from the lower layers and a roundish section crumbles away leaving a large but shallow crater with a secondary smooth road-surface a couple of inches below the level of where the rest of the road is.
When it rains and they start to fill there is no way to know if they are only a couple inches deep or go all the way down to Hades. Since they are very shallow it doesn't take much rain at all to totally fill them to the point where they almost disappear -while deeper potholes that go all the way down to the substrata usually don't get filled to the top unless it is really raining hard.
I hate these ninja potholes. They aren't bad for cars as they are not very deep but on a bike any pothole can be an issue especially for the thin-wheelers.
Ha, Ninja potholes! I like that.
I hate, hate, *HATE* the innocent puddle that turns out to be a bike eater. ARrggghgghh!
Thank goodness the plowed snow "curbs" are melting. All too often they forced me to have to ride full on in traffic to avoid the mystery puddles. I'm fully confident to ride in traffic (and do it every day), but I am tired of people honking at me to get out of the road. :::sigh:::
I've been seeing a lot of "time tunnels" in Blue Island lately. There are some particularly impressive stretches on Greenwood, just S. of 123rd Street. Of course, all of Blue Island is pretty much road acne or Swiss cheese. :-( LIke an earlier poster, I had to replace a good tire two weeks ago due to a beginning sidewall tear, no doubt created as a result of having to ride cr*ptastic roads every day.
Saw something the other day that I'd probably get run over trying to get a photo of. Crossing the Wells St bridge just North of Wacker I avoided the bike lane on the right due to very slippery snow. While on the grating I just noticed rusted out areas of the grating that had sharp edges and maybe could grab a bike tire hitting it just right. Kinda scared sh**less for a moment.
What would you call that?
Last summer, on Oakland and north in Milwaukee's East Side, we had the Mother of All Sinkholes. It was so big that it swallowed up a traffic signal and a Cadillac Escalade SUV. This hole took a couple of months to fill in, but before that could happen, the traffic signal and the SUV had to be fished out. Problem was, the Escalade had a practically full tank of gas when it fell into the sinkhole.It took about a week of constant running before the Escalade finally ran out of gas. I saw the extraction of both traffic signal and Escalade. Its owner has since gotten a new one.
Black Holes?

where the street has caved in and you can't see anything but blackness
Are there pictures? SUV-eating sinkholes definitely need to be documented.
