Pothole Patching in Saint Paul
The City of Saint Paul strives to provide safe and well-maintained streets. Taking care of potholes in a timely manner prolongs the useful life of streets and reduces future maintenance and rehabilitation costs.
Public Works crews fill potholes year-round. Several pothole patching crews are sent out each day to repair main (arterial) and residential streets across the city. On average, a crew will hand shovel 15-20 tons of asphalt per day to improve street conditions.
In Cold Temperatures
In the winter, potholes are patched with a special type of asphalt called “winter mix.” Winter mix uses a softer, stickier asphalt that can be compacted into a hole even in below-freezing temperatures. Winter patches are temporary as the mix warms with the spring and summer temperatures and the material becomes too soft to stay in place.
In Warm Temperatures
In the spring, summer and fall, potholes are patched with “hot mix” asphalt - the same asphalt used to build new roads. Hot mix patches last anywhere from a year to several years. Hot mix is not available until late March or April, depending on weather conditions.
