Okay! Whats going on with the downtown connector uneven roads. (transportation, rated)

If there is a big pothole in the middle of a major freeway that's been there for a month yes I do expect them to know about it.

Last summer I seemed to hit the same damn hole on 285WB. 2nd lane from the right just past Buford Hwy. Finally I learned and avoided it.

The one I have been learning to avoid is in the right lane as 285EB leaves the 75 interchange.

I am pleased to report they finally patched that giant hole! Lets see how long it lasts.

Major sections of 75/85 are badly degraded.

As I said, I suspect this had to do with the winter treatments before the minor snowstorm we had. It's well known and researched that different de-icing and treatment methods can destroy paving sections by causing the petroleum binders in the pavement to disintegrate, thereby causing the aggregates to break free.

Both MgCl2 and CaCl2 deicers are known to deteriorate concretes containing
reactive dolomite aggregates by accelerating the alkali-carbonate reaction (ACR) [32,33].
No literature was found to report potential effects of NaCl on ACR. Based on a modified
ASTM 1260 mortar bar test, ongoing research by the Innovative Pavement Research
Foundation (IPRF) found that the acetate/formate deicers could induce increased levels of
expansion in concrete with ASR-susceptible aggregates, and could trigger ASR in
concrete that previously did not show ASR susceptibility [36,37,38].
While chlorides have little negative impact on asphalt pavements, asphalt
durability problems due to the use of acetate/formate deicers can be traced back to the
1990s, when degradation and disintegration of asphalt pavements, softening of asphalt
binders, and stripping of asphalt concretes were found to occur together with loose
aggregates on the runways at some Nordic airports [39,40]. The mechanisms appear to
be emulsifications and distillations, as well as the generation of additional stress inside
the asphalt pavement. The degradation of concrete pavement from acetate-based deicers
has also been observed at U.S. airports, with damage caused at the site of airplane deicing
costing an estimated $10-60 million to repair at one airport (Colorado Springs Airport),
part of which may be attributable to poor construction. Recent laboratory research at WTI
has found that acetates can cause significant emulsification of asphalt and thus strength
loss in asphalt concrete [41].

I sure hope GDOT investigates thoroughly the decisions made regarding their road preparation and suitability with the porous pavement underneath. Using a ballpark estimate of 650,000 SY of surface area on the Connector and $30/SY, that pervious pavement layer is roughly a $20 million asset.

Personally I'm not holding my breath.

I agree with your assessment. Thanks for posting that information. Unfortunately I too am not holding my breath.

Why aren't each and every one of you reporting these issues to GDOT?

Remember, here in Georgia there's not much oversight of anything.

Who says we aren't?

I actually would like to start reporting things. There used to be a pothole phone number for The Pothole Posse. I don't thin that's active any more. I really want to start reporting traffic light BS. The last time I did it, the issue seemed to be fixed within a couple of days, and has remained fixed since.

They used to have a webpage or something where you can report it. I think now you have to call. That makes it much more difficult.

My mom used to be on a first-name basis with the people in charge of traffic lights in her city because she called them so much.

My take on it is that these are not some obscure problems that need to be exposed and reported. These are things that are painfully obvious to anyone with eyes and wheels.
