Why are you putting “tar and gravel” on our paved road?

The process called “sealcoating” is a relatively low cost method of pavement preservation that helps prevent water from seeping into and softening the base of the road. This restricts compromising elements like cracks and potholes from forming. 

The tar-like substance is actually an emulsion of water and liquid asphalt which penetrates and seals small cracks in the existing pavement. The “gravel” is actually a pea-size aggregate that sticks to the emulsion and, after rolling and sweeping, provides a skid-resistant surface to improve safety.  
 
As vehicles travel over the new surface, some of the aggregate may come loose under the tires. When a motorist encounters a newly chip sealed road, which will be marked with "Loose Gravel" signs, the best practice is to reduce one’s speed and keep plenty of distance from the vehicle in front of you.
