From RMC Research & Education Foundation:

The RMC Research & Education Foundation is proud to announce the release of its latest pervious concrete research report. The study Portland Cement Pervious Concrete Pavement: Field Performance Investigation on Parking Lot and Roadway Pavements was conducted at Cleveland State University over a three-year period. Field observations and testing were conducted at sites in Ohio, Kentucky, Indiana, Colorado, and Pennsylvania with results validating that pervious concrete has performed well in freeze-thaw environments, with little maintenance required.

Notable points Comment: Little Maintenance required – music to our ears, if it holds up. Inclusion of freeze-thaw climate areas should answer some questions that have been lingering for some.
