Pavement Management Program
The City incorporates two types of resurfacing applications. The first is asphalt overlay, a mixture of coarse rock and asphalt 2 inches or more in depth. The second is slurry seals, a mixture of fine rock and emulsified asphalt that is placed on the pavement about one-fourth-inch thick to protect and seal the surface from the elements.
Roads rated in good condition in the City’s Pavement Management Program may be selected for slurry-seal application. Roads that would not benefit from slurry seal are ranked in priority for re-pavement at a later date.
Spray Injection Patching
Spray injection information:
Spray injection is a proven industry standard to repair potholes and other types of roadway imperfections.
The process of spray injection includes cleaning of the area to be repaired with air pressure.
A tack coat of heated emulsion is placed.
The pothole is then filled with granular material coated with heated emulsion.
Once the hole is filled, a dry layer of granular material is placed on top and the roadway is ready for traffic.
Spray injection does have a kick off of aggregate. Streets will be swept by the City approximately 30 days after the application.
Slurry seal information:
Slurry Seal is a proven industry standard used to preserve roads in good condition and extend pavement life.
Prior to application of slurry seal, roads are prepared using crack seal or asphalt patching.
The City uses different processes of slurry seal that are a mixture of fine aggregate and emulsified asphalt. The mixture is applied to prepared road surfaces.
The slurry seal coat requires 24 to 48 hours to cure but can be driven on within a few hours after application.
Slurry seal has a kick off of aggregate. Streets will be swept by the City approximately 30 days after the application.
Residents will be notified at least 24 hours prior to the slurry-seal application on their street and will be asked to park on a neighboring street while work is being completed.
An independent material-testing laboratory will be contracted to perform testing of the slurry materials to ensure that it meets project standards.
