A chip seal is a coating of liquid asphalt and rock chips applied to the existing roadway to extend the life of the pavement. There are four steps in the chip sealing process – applying an oil patch to the most degraded areas, putting down the chip seal, sweeping up excess rock chips and fog sealing (applying a thin coat of asphalt on top of the chip seal).

30991

Though your street is in basically sound condition, it needs routine maintenance to protect it. Chip sealing, which is effective for 7-10 years, stops water from seeping through the surface and damaging the pavement and road base. It costs less to apply chip seal to the street surface than to fix the street base if it is damaged.

30991

Once oil patches are applied, they are allowed to cure for one-two weeks before the chip seal is added. The sweeping and fog sealing are done as soon as possible after the chip seal, usually within 1-2 days based upon weather and the availability of work crews. While the surface can be driven or walked on at any stage, after the process is complete it takes about two weeks before the chip seal is firmly set.

30991

If it is raining or if rain is in the forecast, we will assign our crews to other work for the day. Chip seal must go on a dry surface. That is also why we ask that you make sure any sprinklers are turned off beginning at midnight the night before the chip seal work is scheduled.

30991

You will receive a notice at your door a few days ahead of time. If it does rain, work may be delayed.

30991

Please move your car off the street from the time the chip sealing begins to the completion of the fog sealing process – a period of approximately 2-3 days. You will always be able to drive through the area, but the entire street surface must be available for the work crews. Please also let family, friends and delivery people know not to park their vehicle on the street during that time period. If a vehicle is left on the street, we try to find the owner, but delays cost tax money. Therefore, cars not moved by the time the work begins will be towed at the owner's expense. If your car is towed, contact the Sheriff's Office, 503-655-8441.

Bridge Maintenance

Our 186 bridges are inspected every 2 years and through those inspections we sometimes find repair and maintenance work that needs to be done to preserve the bridge structure and keep it safe for travelers. That work often includes bridge scour projects, either removing excess soil from stream channels or replacing soil around foundations that has been washed away during high water events.

Pavement Rehabilitation

Pavement rehabilitation includes treatments that extend the life of an existing road surface such as surface sealants, patching short spans of roadway and asphalt paving. These proactive measures add structure to the road, remedy pavement distresses, and maintain a road's condition to defer full reconstruction further in the future. See schedule for next five years.

Scheduled pavement rehabilitation projects in unincorporated Clackamas County (schedule could change):

A chip seal is a coating of liquid asphalt and rock chips applied to the existing roadway to extend the life of the pavement. There are four steps in the chip sealing process – applying an oil patch to the most degraded areas, putting down the chip seal, sweeping up excess rock chips and fog sealing (applying a thin coat of asphalt on top of the chip seal).

30991

Though your street is in basically sound condition, it needs routine maintenance to protect it. Chip sealing, which is effective for 7-10 years, stops water from seeping through the surface and damaging the pavement and road base. It costs less to apply chip seal to the street surface than to fix the street base if it is damaged.

30991

Once oil patches are applied, they are allowed to cure for one-two weeks before the chip seal is added. The sweeping and fog sealing are done as soon as possible after the chip seal, usually within 1-2 days based upon weather and the availability of work crews. While the surface can be driven or walked on at any stage, after the process is complete it takes about two weeks before the chip seal is firmly set.

30991

If it is raining or if rain is in the forecast, we will assign our crews to other work for the day. Chip seal must go on a dry surface. That is also why we ask that you make sure any sprinklers are turned off beginning at midnight the night before the chip seal work is scheduled.

30991

You will receive a notice at your door a few days ahead of time. If it does rain, work may be delayed.

30991

Please move your car off the street from the time the chip sealing begins to the completion of the fog sealing process – a period of approximately 2-3 days. You will always be able to drive through the area, but the entire street surface must be available for the work crews. Please also let family, friends and delivery people know not to park their vehicle on the street during that time period. If a vehicle is left on the street, we try to find the owner, but delays cost tax money. Therefore, cars not moved by the time the work begins will be towed at the owner's expense. If your car is towed, contact the Sheriff's Office, 503-655-8441.

Pavement Preservation

To extend the life of a road, surface treatments are applied the existing roadways throughout the county including slurry seal and chip seal. A slurry seal is a coating of liquid asphalt; a chip seal is a coating of liquid asphalt and rock chips. See schedule for next five years.
