Abstract:
Pevious concrete, with its ability to act as both a structural pavement and a stormwater mitigation system, has been identified as a best management practice (BMP) to efficiently manage stormwater runoff and reduce stormwater pollution. In addition to its stormwater benefit, using fly ash as a recycled cementitious alternative to cement promotes sustainability even further. Despite the benefits and significant research and development on pervious concrete, its acceptance in cold climates is still limited. Vulnerability to freeze-thaw and salt exposure has led to uncertainty about its long term performance. Additionally, the current standardized freeze-thaw testing procedure is not recommended for pervious concrete, as it is not representative of field conditions.
Therefore, the specific objectives of this study were to: (1) determine the effects of deicing salts on pervious concrete, using a modified and more field representative testing procedure that involves slow freeze-thaw cycling in drained condition, and (2) determine the effects of cement replacement with increasing amounts of fly ash on the freeze-thaw, durability of pervious concrete.
