Long Term Drainage Performance of Pervious Concrete Pavements in Canada


Pervious concrete pavement is an eco-friendly pavement system which can offer various
and sustainable benefits for stormwater management. It can be considered as an
alternative to impervious pavement system as the open void structure of pervious
concrete pavement allows water to infiltrate very quickly through it and join the natural
ground water. Though pervious concrete pavement has been used in parts of Europe
and the southern United States for many years, the practice of using it in northern cold
climates such as Canada is more recent.
Several pervious concrete pavement field sites were constructed by the Centre for
Pavement and Transportation Technology (CPATT) at the University of Waterloo, the
Cement Association of Canada, and several other industry members. Initial results from
this work have been published previously, and include the performance analysis,
permeability evaluation, and strength assessment. However, collecting drainage
characteristic data from instruments such as the moisture gauge measurements, strain
gauge at three sites have continued to be monitored. This field/laboratory study is
providing insight into the short and medium term drainage performance of pervious
concrete pavement.
As a continuation of previous work, this paper discusses the effect of mix design in the
performance of pervious concrete, the long term drainage instrumentation performance
that have been obtained from instrumentation at sites in British Columbia, Ontario and
Quebec. An analysis framework is also presented in this paper. The findings from this
paper will provide useful information for designers and practitioners on the long term
drainage performance of pervious concrete pavement
