What is Pavement Management?

The City of Hillsboro owns and maintains more than 240 miles of roadway. Pavement maintenance and repair helps keep these roadways in good condition.

Through the Pavement Management Program (PMP), City staff evaluate major roadways annually and local streets every three years.

The information collected is used to set each road’s Pavement Condition Index (PCI), or pavement condition score. A PCI of 0 means the pavement has failed and a score of 100 means the pavement is brand new. For roadways owned and maintained by the City of Hillsboro, the average PCI is 83.

When planning pavement maintenance projects, the City considers: 

  • PCI
  • Current and projected budget
  • Coordination with other utility and roadway projects

Projects may include:

  • Crack seals: Filling cracks with hot sealant to keep water from getting into the cracks and damaging the road
  • Slurry seals: Protecting pavement with a mixture of very small crushed rock and liquid asphalt cement placed over the whole surface
  • Overlays: Repaving the top layer of a roadway
  • Asphalt or concrete replacement: Completing small asphalt or concrete patch repairs

Are you wondering about the condition of the roads in your neighborhood and in Washington County?
