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  Maintenance Divisions.
• The Asphalt Plant (bulk storage).
• Heth Run (City of Pittsburgh storage facility in Highland Park for bulk Storage.
