Potholes

The method that the City uses most often is "place and roll’ or "quick response" pothole patching. This method usually utilizes a two-man patch crew in a small dump truck assigned to repair potholes in specific areas in the city. The areas are assigned on the basis of traffic volume. Unlike quality patching, this type of repair is not intended to repair fatigued sections of pavement. Place and roll patching addresses an immediate need for filling potholes in the road with asphalt mix and making the road safe for the traveling public. City pothole patching crews can usually fix the majority of potholes before complaints are registered. We will attempt to fill the hole within 24 hours of notification at the Street Department and the weather allows. This type of response is needed to mitigate immediate risk to vehicles traveling on a city-paved road. Without this type of response, frequent vehicular damage from driving through potholes could occur.
Repair of potholes by place and roll patching is accomplished by:
1. Cleaning the hole with a broom (if needed).
2. Shoveling a pavement repair material into the pothole to the correct depth.
3. Raking the material smooth unless a self leveling material is used.
4. Compacting the asphalt mix by rolling the patch with the tires of the patch truck, using a vibratory plate compactor, or (with very small holes) using a hand compaction device.
Work zones for this type of work are categorized as "moving" work zones. Traffic lane closures are not needed.
