Concrete & Pavement Management Program
Concrete Repair and Replacement
Concrete infrastructure can fail for a variety of reasons – soil movement is the main problem. The surface of the concrete may also deteriorate due to environmental factors such as freeze/thaw cycles. Concrete repairs and replacement are prioritized based on the overall condition, but the annual amount of concrete replaced is limited by budget availability.
Road and Bridge regularly inspects and assesses the condition of concrete to determine the appropriate repair. Repairs include a combination of patching and grinding to ensure safe passage for pedestrians.
Road and Bridge replaces deteriorating curb, gutter, and sidewalks throughout Unincorporated Jefferson County. This program is currently performed by Silva Construction and is managed by Road and Bridge.
The Concrete Criteria Rating system is designed to evaluate existing concrete conditions and prioritize concrete replacement. The concrete conditions are determined by various characteristics such as vertical separation, severe ponding, fracture, spalling and missing concrete.
Concrete to be replaced is marked with pink paint.
Notification flyers are posted on doors advising residents of upcoming concrete replacement and paving operations. The flyers will explain the cooperation needed from residents to minimize inconvenience and expedite the project. Residents are given as much notice as possible, typically between 12-48 hours to move vehicles off the roads. If residents do not comply, vehicles will be towed to a nearby location.
Be aware of the heavy equipment and increased activity while driving in the area. Resident cooperation is required in observing the traffic control barricades, warning devices, and "No Parking" signs that are in place. Please water lawns after working hours; excessive water will damage fresh concrete.
When do crews work?
During the Spring and Summer months, work hours will begin at 6:30 A.M. In the case of inclement weather, work will be delayed.
Use of deicing materials
Applying de-icing materials to new concrete (within one year) will cause spalling and chipping of the concrete.
How are Roads selected for work?
Road and Bridge maintains approximately 2900 lane-miles of asphalt roadway. It would take 190 lane-miles of overlay each year to prevent overall deterioration of the road network.
Road and Bridge uses Cartegraph, a pavement management system to analyze its road network. The Pavement Condition Index (PCI) has a numerical value from 0 (failed) to 100 (excellent). Road segments are prioritized based on the numerical PCI as well as traffic volumes. Once roads are prioritized, they are scheduled for overlay based on budget availability.
Remove and Replace (R&R) patching involves the complete removal of the existing asphalt in a localized area followed by full-depth placement of new asphalt. Potholes will be filled with asphalt, and larger areas are removed with a roto-mill machine.
An application of sealing material is used directly in the cracks of the pavement surface to prevent moisture damage.
The overlay process consists of roto-milling (grinding off) the existing failed surface and then placing a new layer of asphalt. In most cases, patching is required to repair damaged areas before asphalt overlay begins.
Notification flyers are posted on doors advising residents of upcoming concrete and paving operations. Residents are given as much notice as possible, typically between 12-48 hours to move vehicles off the roads. If residents do not comply, vehicles will be towed to a nearby location.
When do crews work?
During the Spring and Summer months, Road and Bridge crews work Monday – Thursday from 6:00 AM – 4:00 PM.
