Pervious Paving Research

From RMC Research & Education Foundation:
The RMC Research & Education Foundation has released a 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.
(Firestone is marketing a pervious paving product made from recycled tire material. Applications for vehicular use seem sketchy, but a sweet specification for hardscapes and walks. Check it out at http://www.firestonesp.com/sustainable_products.asp)
