Slurry Seal Program

The Slurry Seal Program allows the City to preserve existing paved streets by applying a thin layer of asphalt. Slurry seal is a petroleum-based emulsion product mixed with fine aggregate rock. It slows down the aging process caused by ultraviolet rays, vehicle traffic wear, effects of temperature changes, or the loss and/or stripping of the asphalt. Slurry also significantly reduces vehicle road noise. Using slurry in conjunction with a Crack Seal Program | Corvallis Oregon  provides the most cost-effective method of preventing premature aging. Slurry sealing is done usually during the summer months, weather permitting. 

Slurry seal is applied between the hours of 7:00 a.m. and 5:00 p.m. Once applied, the slurry will dry in about two hours. All work is dependent upon favorable weather conditions. If a street is not sealed on the date specified due to equipment failure or rainy conditions, it will be rescheduled. Residents will be re-notified 48 hours in advance of the new date by the contractor. Weekend work may occur in the event of equipment failures or rainy weather. 

Traffic and on-street parking are prohibited while the work is being performed. Residents on affected streets will receive an informational door hanger prior to the beginning of work. NO PARKING signs will be posted approximately 48 hours in advance of the day slurry-sealing will occur on a street. The signs will state the exact closure date and time period. When looking for a place to park while a street is being worked on, check the times and dates carefully on any signs encountered – they might not apply to "today"!
