Annual Program Treatments
Pavement surface treatments are applied to county roads to maintain the health of the road network
Pavement Condition Assessments
The existing pavement condition of each County-maintained road is assessed or “rated” every three years. One third of the County’s roadway network is rated each year. A visual inspection is performed by a trained inspector to quantify the severity and extent of each of 14 different pavement and roadway deficiency categories including potholes, rutting, cracking, etc. For each deficiency category, a deduction value is established based on the severity and extent observed on that roadway segment. The sum of the deduction values for each category is subtracted from a perfect score of 100 resulting in a modified pavement condition index (PCI) rating for each roadway segment. In general, roads with lower ratings exhibit greater deficiencies than roads with higher ratings. Condition ratings are reassessed every three years and changes in rating are monitored over time. Current pavement condition rating information is available via the Pavement Ratings layer of the Web Map below.
Program Development
Pavement condition ratings are a useful tool in the treatment selection and project prioritization process. Pavement maintenance treatments are divided into two major program areas: a) Routine and Preventative Maintenance, and b) Rehabilitation and Reconstruction. Routine and Preventative Maintenance treatments include localized permanent patching, crack sealing, slurry sealing/microsurfacing, cape sealing, and hot-in-place recycling with microsurfacing. Rehabilitation and Reconstruction treatments include hot mix asphalt resurfacing, mill and overlay, full depth pavement reconstruction, and full roadway reconstruction with replacement of curb and gutter and/or sidewalk. Treatment selection is based on deficiencies observed and projects are identified based on selected treatment and project size. A project can be as small as only a portion of a single road or as large as an entire subdivision of roads depending on the treatment, established priority, and available funding. Projects are prioritized and organized into annual programs based on available funding. Current program information including funded maintenance resurfacing projects is available via the Pavement Program layer of the Web Map below.
Web Map
The Infrastructure Management Division has developed an interactive web mapping application to assist you in exploring Pavement Condition Ratings as well as current Pavement Program information including funded maintenance resurfacing projects. You can use your web-browser to access this map. Supported web browsers include Google Chrome, Internet Explorer, and Safari.
