Patching & Pothole Filling

Overview - Potholes

Potholes form due to water that weakens the soil beneath the pavement and traffic loading.  Winter and spring bring continuous freezing and thawing periods that can have a devastating effect on asphalt and concrete streets. 

The Operations Division fills potholes year-round to mitigate the damage to the roadway.  During 2014, approximately 5,000 potholes were filled by City crews throughout the calendar year. 

In the winter months, a temporary patch is made with a "cold mix" asphalt product.  "Cold mix" asphalt is used when weather conditions are not favorable for more permanent patching. 

In warmer weather, "hot mix" asphalt is used to as a semi-permanent patch to restore the driving surface of a roadway where potholes form.  The City operates a dump truck with a "hook-lift" roll-off style body that heats hot mix asphalt for road application.

The City of Janesville also owns a single-operator "Pro-Patcher" truck that spray-injects patching material into potholes and larger cracks.  This piece of equipment works best on concrete pavement, but it may also be used for bituminous (asphalt) pavement pothole filling.

Overview - Pavement Patching

The Operations Division is responsible for performing small to medium sized pavement repairs in areas where excavations occur or pavement is damaged to the point that a simple surface patch will not suffice. 

Pavement repairs are completed on small to medium sized areas of pavement if the following occurs:

  • Water main break
  • Electrical or plumbing excavation
  • Pavement "blowup" or heaving
  • Deterioration of existing repairs
  • Heavy, localized deterioration of pavement (alligator cracking)

Large-scale pavement rehabilitation, resurfacing, and reconstruction efforts are coordinated through the Engineering Division
