Slurry seals are typically applied during warm, sunny weather to accelerate the curing process. The application process requires a one-day road closure. The benefit of the slurry seal application, however, can be hard to see in the first few weeks after the streets first receive slurry seal. Initially, the surface is gritty, where it may have once been smoother. This initial grit is normal. And it is not permanent. The first phase of your street’s transition toward smoothness is the street sweeping, which removes all of the loose aggregate (small rock). This occurs approximately one week, three weeks and two to three months after application. The second phase of that transition is more subtle. And its main ingredient is time. Over time, automobile traffic will dislodge the larger, sharper pieces of aggregate that initially give the road its rough, gritty surface. Traffic will also push the remaining aggregate deeper into the surface. Within a year or so, the smooth road residents remember before slurry seal will be back—with an extra three to seven years of extended life infused into it.
As an example for 1000-feet stretch of residential street:Slurry Sealing - $ 12,000 (engineering and construction costs)Asphalt Overlay - $120,000 (engineering and construction costs)Road Reconstruction - $500,000 to $600,000 (engineering and construction costs)
Slurry sealing streets can save near one-tenth of overlay or one-fiftieth the cost of a total reconstruction.
When the slurry is applied, please do not drive on it for at least 4 hours or until notified by the contractor. Driving on the fresh slurry damages vehicle undercarriages. Also the cost of reapplying the slurry may be the responsibility of the vehicle owner. For a short video, please click here.
Driving on the fresh slurry will damage your vehicle and you may be held responsible for the cost of reapplying the slurry. Please plan ahead.
