Asphalt Resurfacing Program
Annual Street Resurfacing Program
The Annual Street Resurfacing Program depends upon the costs of and available budgetary allocations selected by City staff, along with ensuring that no conflicting projects, including private development, may impact the streets in the near future. Streets on the annual resurfacing list may also include periodic replacement of severely damaged curb and gutter that restricts proper drainage. Additional factors considered before resurfacing a section of the street include curb replacement, recent or planned utility work, stormwater drainage system improvements, and current or planned residential or commercial construction affecting the road.
Asphalt resurfacing involves completely removing and replacing the top layers of asphalt. Patching is typically done before the final top layer of asphalt is poured, providing structural rehabilitation of the roadway. Asphalt resurfacing is typically performed when other preservation tools no longer benefit the asphalt and must be removed entirely/replaced. Due to the work required, asphalt resurfacing costs much higher than pavement preservation methods.
How Does the City Prioritize Street Maintenance as Related to Asphalt?
A Pavement Condition Index (PCI) score is applied to street segments and rated on a scale from 0 to 100. Staff then uses these ratings to develop a comprehensive pavement management system to prioritize street maintenance work delivered through the Annual Street Resurfacing Program and Annual Pavement Preservation Program.
Streets across the City may require different preservation methods due to factors that impact the PCI score on any given segment. This may be due to the age of the pavement of each street from original construction or phases, traffic volume differences, drainage patterns, recent utility work performed, etc. Developing a comprehensive pavement preservation program enables City staff to utilize available funds efficiently and fiscally responsibly while reducing long-term maintenance costs on the overall street segment.
