Well, if Pittsburgh is using it, it is terrible. We have so many potholes (and huge ones). It has become much worse over the last ~5 years. For several months we had a multi-foot hole blocked off by cones until the city could fix it. It essentially was in the middle of a two way road. It was terrible. I see more and more each winter.

That's not because of the cement but the geology of Pittsburgh itself. Limestone bedrock and the "underground river" contributes to potholes and other geologic anomalies. If anything, adding bioswales and having a way to put the water back into the ground would stop the potholes from happening in the first place.

Yes, but that still doesn't mitigate the rapid freeze/thaw effects on the concrete/asphalt that the City of Pittsburgh uses.

I think you are confusing sinkholes and potholes. The two aren't really related.

That sounds, from your description, more like a sink hole than a freeze-thaw induced crack? Hard to tell without seeing it.
