Fixing Potholes
Structural repairs will be made for failed pavement areas. Failed areas of the roadway pavement will be cut out and removed (up to 6 inches deep). Then the excavated areas will be rebuilt with an equal amount of asphalt concrete.
Installing Curb Ramps
As part of the City’s intensive pothole and street repair program, curb ramps will be installed at almost 300 intersections in 2008. Curb ramps provide access between the sidewalk and the street for people in wheelchairs and improve safety for moms using strollers, etc.
Curb ramps are short ramps that either cut through a curb or that are built up to it. When curb ramps are cut into curbs, they are sometimes referred to as "curb cuts." Newly installed curb ramps must be flush with the streets and include detectable warnings (raised lines) for people who have visual impairments.
Typical Curb Ramp installation takes about four days:
1. Demo/Base Rock
2. Build forms
3. Pour cement and let it cure
4. Finish work such as painting and textured guides
Resurfacing
Resurfacing involves applying an overlay or seal to the surface of the roadway. This protects the roadway and slows its rate of deterioration, as well as creates a smooth surface. After the resurfacing is completed, pavement markings, striping and signage will be replaced or upgraded as appropriate. The four resurfacing methods the City plans to use are: Micro Seals, Cape Seals, Slurry Seals and Asphalt Overlays of various
thicknesses. The type of treatment chosen for each street depends on the current pavement condition and economic factors.
Micro Seals and Cape Seals
Micro seals and cape seals are thin resurfacing treatments used for streets that are relatively structurally sound.
Slurry Seals
A slurry seal is another type of thin resurfacing treatment used for streets that are structurally sound. It is installed relatively quickly.
Asphalt Concrete Overlays
This treatment is used for streets that are structurally deficient and involves placing a layer of new asphalt concrete over the entire roadway.
