Behaviour and Performance of Pervious Concrete Pavement in Canada

Pervious concrete offers sustainable and environmental benefits for stormwater management and urban development. Pervious concrete can be used in low volume, low speed applications in urban and rural settings without creating impermeable space. Therefore it is a low impact development that does not put additional demand on the stormwater management system and in some applications will lower the demand on the stormwater management system. Recent use of pervious concrete in Canada includes four test areas that were constructed to evaluate the performance of pervious concrete in a freeze-thaw climate. The test areas are monitored regularly through surface distress evaluations, permeability and light weight deflectometer testing. Laboratory testing is carried out to evaluate performance in accelerated freeze-thaw testing, compressive and flexural strength, void content and permeability. Two of the test areas are instrumented with moisture sensors and static strain gauges. The data from the instrumentation is available in real time which allows for efficient comparisons and evaluations. The ability for pervious concrete to drain moisture from the surface is measured through permeability testing and development of distresses on the surface are noted in surface distress evaluations. This paper includes the findings to date from the various field and laboratory testings and the data collected from the instrumentation.
