David S. • ...an ASTM test method and acceptance criteria (typically expressed as mass lost after X number of cycles) for freeze-thaw durability when exposed to deicing salts. C666 is a joke. The industry needs to provide designers and users with assurance that pervious concrete will perform in the long term (15-25 years) without raveling and degradation when subject to cold climate conditions.

Dale F. • David...several ASTM tests for pervious concrete in the works but no freeze-thaw. This should not be to hard to produce. Would C1645 be a good starting model? Not sure how to quantify life cycle though. How do you measure projected service life with pavers?
