Overview and History
The City’s long-term road surface maintenance program is intended to maintain the City’s road system to the highest average condition rating with the funds available. The City is continually exploring the utilization of treatment strategies as new technologies are developed that are cost effective and that maximize the overall condition of the pavement network. Currently, the City’s program is using various thicknesses of asphalt overlay and bituminous surface treatment (BST) as pavement treatment technologies.
Asphalt overlays, generally, return the pavement to full structural capacity and can extend its service life by 15 to 30 years. BST applications, typically, extend the useful life of local streets by 7 to 10 years. Both treatment strategies increase skid resistance and improve the ride quality. The program timetable is to implement overlays in even-numbered years and BSTs in odd-numbered years.
City Policy requires that new pavement not be cut for a period of five (5) calendar years after the year of construction. This applies to new construction and pavement overlays. Street segments to which this policy applies are shown on the Moratorium Map.
The latest 5-Year Plan is from 2019 to 2024. In the summer of 2019, the City will be implementing BST in the Hillwood and Richmond Highlands neighborhoods. Although overlay is supposed to be done in even-numbered year, there is an overlay project that was missed in 2018 which will be done in 2019. The project is the NE 175th Street Pavement Preservation.
