Slurry Seal

Much like applying a seal coat to your driveway, slurry seal is spread in a thin layer over the roadway surface. The material consists of finely graded gravel, an asphalt binder, and additional emulsifier additives. The slurry seal binds with the surface to protect it from the sun and the elements, as well as from wear and tear of vehicles. The rough surface, which wears down over time, is hard wearing and promotes traction and prevents slipping. The road is closed to traffic for several hours while the material cures.

Crack Fill

A crack fill treatment generally involves using an air compressor to clean out the cracks in the pavement and then uses an applicator to inject a hot-applied crack sealant. Crack filling reduces the ability of water and other materials to get into the pavement which degrade it. A rolling lane closure is used for the cleaning of the cracks and application of the sealant but through traffic is maintained at all times.

Pavement Rejuvenation

A pavement rejuvenator is a material that is sprayed upon relatively new roadway surfaces to reverse the ageing effects of sunlight and water. It improves the durability of the pavement by restoring essential oils to the asphalt the help reduce sunlight and water penetration, extending the life of the roadway. Once the initial treatment is applied, a thin layer of sand is applied to assist in curing and preparing the road for traffic. Through traffic will be maintained at all times but some delays should be expected.  Caution is recommended while the material cures, typically 3-4 hours..

Cape Seal

Cape seal combines the advantages of a chip seal with a slurry seal. Chip sealing is the application of a thin layer of asphalt combined with a layer of small gravel. A chip seal can be driven upon within a few hours. Chip seals leave behind a coarse, abrasive surface that can temporarily cause increased tire noise and a rough ride for bicycles, skateboards, roller blades, etc. Loose gravel and dust may also be temporarily present, which will be periodically swept up. After the chip seal cures for a couple of weeks, a slurry seal is installed,  significantly reducing any tire noise and dust, and binding the remaining rock into a smooth and hard wearing surface. The road is closed to traffic for several hours while the slurry seal cures.

 

Plane and Overlay

With this treatment, the existing asphalt surface layer is removed by grinding or milling it off and then applying a new asphalt surface layer.  Curb repairs and curb ramp repairs are typically completed before the pavement is milled.  After the pavement is milled, repairs to the underlying pavement structure are made if necessary.  Through traffic is maintained to the greatest extent possible but minor delays should be expected during asphalt placement and compaction.

Full Street Reconstruction

If the condition of the street is precludes the use of preventative surface treatments, then the full depth of the pavement is removed and an entirely new roadway is constructed. Reconstruction of the roadway generally includes new curbs, ADA-compliant accessibility ramps and the removal and replacement of a portion of driveway approaches. This work is frequently coordinated with utility improvements such as replacing old water mains and services, storm sewer and sanitary sewer improvements.
