The City typically uses five major programs to improve, repair, and maintain its pavement network. Staff reviews the pavement conditions each winter and spring and makes recommendations of which streets to include into the annual programs to the City Council as part of the Capital Improvement Plan process. The programs for the 2016 construction season are briefly described below.
Asphalt Pavement Resurfacing
This project involves removing and replacing the top few inches of asphalt pavement and is generally performed on asphalt streets with significant deterioration. The 2016 program concentrates on streets along Olive Boulevard that have been in need for some time.
Concrete Pavement Replacement
The concrete pavement replacement project involves the removal and replacement of failed concrete pavement and curbing. Streets are included in this program to address a specific hazardous section, to support other pavement programs, or to make an overall improvement to a deteriorated street.
Microsurfacing is a surface seal that helps preserve asphalt pavement that is in good condition and that can be used to delay asphalt resurfacing. The City’s Public Works crews typically begin pavement repairs on streets in this program up to a year in advance of the microsurfacing
. This project typically concentrates on neighborhoods rather than individual streets.
Roadway reconstruction is reserved for streets that have reached the end of their useful lives and can no longer be maintained. The current reconstruction project is a continuation of work that was completed this spring.
The City dedicates approximately 10% of its pavement maintenance budget for sidewalk improvements, with the goal of bringing its entire sidewalk network into compliance with current accessibility standards. Curb ramps, broken sidewalk, and tripping hazards are included in this program, which often coincides with or precedes roadway improvements on the same street.
