During the Annual Crack Seal Program, a hot-pour, petroleum-based pavement crack and joint sealant is used to fill cracks in City streets. The sealant contains a minimum of 18% recycled tire rubber and forms a long lasting, resilient seal in cracks and joints which is flexible and expandable in varying and extreme pavement temperatures. The sealant will prevent the invasion of surface water between the layers of asphalt and sub-grade rock, thus preventing premature failures, deterioration and potholes. Using crack seal in conjunction with slurry seal provides the most cost-effective method of preventing premature pavement failures and aging.

Streets are not closed during crack-seal work, but on-street parking is prohibited so the contractor has full access to the work area from curb to curb. Residents on affected streets will receive a mailing with a detailed schedule of streets to be crack-sealed prior to the beginning of work. Crack sealing is done annually, usually from July through September, and a schedule is published here once it is established.

2017 Crack and Slurry Seal Program

Crack and slurry seal will be applied to the following Corvallis streets between the hours of 8 a.m. and 5 p.m. All vehicles must be removed from the street no later than 8 a.m. or they may be towed. Sidewalks will not be closed. The contractor will notify affected residents by doorhanger 48 hours before the work begins.

Frequently Asked Questions

What is crack seal?

Crack seal is a hot, sticky, petroleum-based pavement crack and joint sealant. It does not resurface the entire street – it just fills cracks. The sealant forms a long-lasting, resilient seal which is flexible and expandable in varying and extreme pavement temperatures. Crack sealing prevents the invasion of surface water between the layers of asphalt and sub-grade rock, thus preventing premature pavement failures, deterioration and potholes.

Is it safe?

Where necessary, the sealant will be covered with a fine layer of sand to limit tracking. However, caution is still advised. When the material is first applied, it is extremely hot (400°), wet, sticky, and very difficult to remove from skin, shoes and floor coverings. For the safety of children and pets, please keep them off the streets on the day your street is sealed.

Will access to my street be affected?

You may drive on the street, but on-street parking will be prohibited. Sidewalks will not be closed. The Post Office and Allied Waste will be notified before work begins, and there will be no interruption of these services during the project.

Why shouldn't I water my lawn or wash my car?

Water interferes with the crack-sealing process, so we ask residents not to water lawns, wash cars, or engage in similar activities that may cause water to enter the street on the day their street is crack-sealed.
