How does County select and prioritize road maintenance projects?
County roads are monitored on a regular basis and assigned a Pavement Condition Index (PCI). This rating, along with the average daily traffic, funding availability, and other factors is evaluated to justify new maintenance projects. Some low volume roadways may only received a minor surface treatment such as a chip seal or slurry seal. Heavily traveled regional or arterial type roadways may received full asphalt overlay or rehabilitation such as pulverization, milling, or other process. The various strategies are analyzed by the department’s Pavement Management Division and Transportation Program Management.
