Implementation of Porous Concrete for Sidewalks in New Jersey

Pervious concrete have been gaining popularity as a potential
solution to reduce the amount of impermeable surface area
associated with sidewalks,reduce puddling, and potentially slow
water surface high flow rates. As important as these benefits are to
surface runoff mitigation, there are concerns with the ability of
pervious concrete mixes to provide sufficient structural support and
longevity for the expected service life of the sidewalks, as well as life cycle costs. The composition of pervious concrete creates limitations to its mechanical strength and challenges in its maintenance to achieve the expected service life. The performance of pervious
concrete sidewalks is relevant to its geographical location, subsurface
conditions, and intended application. This requires constructing test
sidewalks made from porous concrete in the field in urban areas.
These sidewalks will be monitored and evaluated overtime to assess
their performance.

The proposed implementation of porous concrete for sidewalks in the
field is needed to evaluate their short and long term performance
over time. This will help provide information on their performance,
service life, life cycle costs, and environmental benefits. The
implementation project requires the NJDOT to select the most
appropriate site to build two sidewalks side-by-side using two
different mix designs of porous concrete. At each site, multiple
sections can be built to evaluate the effects of construction and
maintenance factors on filed performance and life cycle cost.
