The sealant 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. Residents on affected streets will receive a mailing with a detailed schedule of streets to be crack-sealed prior to the beginning of work. Using crack seal in conjunction with slurry seal provides the most cost-effective method of premature failures and aging. Crack sealing is done annually, usually from July through September.
Slurry seal is a petroleum-based emulsion product mixed with fine aggregate rock.
Slurry also significantly reduces vehicle road noise. Residents on affected streets will receive a mailing with a detailed schedule of streets to be slurry-sealed prior to the beginning of work. Using slurry in conjunction with a crack seal program provides the most cost-effective method of preventing premature aging. Slurry sealing is done annually, usually from July through September. Surface patching of arterial and collector street pavements is done during the dry-weather months, usually from July through September.
