Concerns over the resistance to the freeze-thaw cycle have limited the use of pervious concrete in cold weather environments.[1] The rate of freezing in most applications is dictated by the local climate. Entrained air may help protect the paste like in normal concrete.[2] The addition of a small amount of fine aggregate to the mixture increases the durability of the pervious concrete.[3] Avoiding saturation during the freeze cycle is the key to the longevity of the concrete.[4] Related, having a well prepared 8 to 24 inch (200 to 600 mm) sub-base and drainage will reduce the possibility of freeze-thaw damage.[4]
