Asphaltic concrete sidewalk An asphaltic concrete sidewalk is a pedestrian walkway constructed with asphalt instead of Portland cement concrete. Asphalt is a flexible paving material made from aggregates bound together with asphalt binder.
Asphalt sidewalks may be used in certain situations where permitted by applicable standards or site conditions. They are generally quicker to install than concrete but have different maintenance and durability characteristics. Material selection depends on project specifications, location, and agency requirements in NYC.

What is an asphaltic concrete sidewalk?
A pedestrian walkway built with asphalt instead of Portland cement concrete, using aggregates bound with asphalt binder.

How does asphalt compare to concrete?
