pothole occurs when there is a small failure in the road surface,
and if left unattended, it will start to degrade the road surface.
Pothole patching is a year round activity which is performed by
the Maintenance Divisions. Each of the Divisions are responsible
for handling all the pothole patching complaints and requests that
are received in their respective areas. Each Division has one or
two asphalt crews that perform the work. Some
examples of patching work performed include:
- Pothole patching.Roadway gutter installation
and or repair (to help water drainage from road surface).Windrow installation
or repair (a "Windrow" is an asphalt curb placed along
the side of the street to aid in drainage). Small intersection
- Small alley paving
(paving of an ally way or area too narrow for paving equipment).
the summer months, the asphalt crews from the Maintenance Divisions
use Hot Mix Asphalt produced by the Asphalt Plant to patch potholes.
a typical day, each asphalt crew will receive two loads of Hot Mix
Asphalt. Each load will weigh between 2-3 tons.
the Maintenance Divisions receive tons of asphalt for Hot Patching.
Cold Weather Patching
In the winter months, when production of Hot Mix Asphalt
is not possible, the Maintenance Divisions use Cold Patch (which
is produced by the City's Asphalt Plant) for pothole patching (Please
see the Cold Patch description in the Paving Processes section for
details on this material). Unlike Hot Mix asphalt which must
be applied while hot, Cold Patch can be stock piled and used when
needed. Stock pile locations for Cold Patch include:
- The Asphalt
Plant (bulk storage).
- Heth Run
(City of Pittsburgh storage facility in Highland Park for bulk
