Pavement Treatments

• Crack sealing is a pavement maintenance technique that involves filling and sealing cracks in asphalt

• It's one of the most effective ways to extend the life of a pavement by addressing cracks that develop over time due to traffic load, weather conditions, and aging.

• The rejuvenating process of applying a specialized treatment to asphalt pavements to restore their flexibility, extend their lifespan, and improve their overall performance.

• The goal of rejuvenating is to reverse some of the aging effects caused by oxidation, sun exposure, and traffic load, which can lead to brittleness and cracking. 

Fog Seal

• Fog seal is a single application, typically light, of emulsified asphalt to an existing asphalt surface. 
• This type of maintenance treatment can be valuable aid to renew weathered (oxidized) asphalt surfaces and improve the surface appearance, seal minor cracks and surface voids, and inhibit raveling as well a preventing moisture from penetrating into the hot mix.

Slurry Seal / Micro Surfacing

• A slurry seal is the application of a mixture of water, asphalt emulsion, aggregate (very small crushed rock), and additives to an existing asphalt pavement surface. 
• A slurry seal is an emulsion with aggregates as part of the mixture.
• The placement of this mixture on existing pavement is the “seal” of the pavement surface. 

Mill & Overlay

• A “mill & overlay” is a street rehabilitation technique that requires the removal of the top layer (typically 2") of a street by the grinding action of a large milling machine. After the top layer is removed, a new layer of asphalt pavement is put in its place.
• Well-designed pavements with a strong base and adequate thickness to support traffic loads will deteriorate from the surface down. Therefore, mill and overlays are an important part of the pavement lifecycle as they replace deteriorated surfaces with fresh new asphalt.
