Daily traffic use, water seeping in from rain, oxidation, and the winter freeze-thaw cycles all prematurely crack and age asphalt. If left untreated, this deterioration can lead to costly repairs in the future.
Fahrner Asphalt Sealers, LLC offers an array of asphalt sealing products that extend the life of your pavement and save you money, including:
- Chip Seal
- Scrub Seal
- Slurry Seal and Micro Surfacing
- Fog Seal
- Parking Lot Sealcoat
- High Friction Surface Treatments (HFST)
Chip Sealing protects pavement against oxidation and water intrusion. It begins with applying asphalt binder, immediately followed by aggregate and then compacted with a roller. This application, done with minimal traffic disruption, improves surface texture and provides excellent skid resistance.
Double Chip Sealing on gravel roads offers a cost-effective way to provide a hard surface and suppress dust.
Scrub Sealing provides crack filling and a tough durable wear course in one process, saving time and overall cost. The process begins with applying and scrubbing an emulsion containing a rejuvenating agent into the cracks and voids with a broom, followed by a thin layer of aggregate and compaction by a roller. Scrub Sealing protects pavement against oxidation and water intrusion and can be done with minimal traffic disruption.
Micro Surfacing and Slurry Seal
Micro Surfacing – comprised of fine aggregates, emulsion, cement and other additives – is capable of filling wheel ruts and producing high surface friction. Micro Surfacing protects pavement against oxidation and water intrusion and is suitable for use on airport runways, interstate highways, as well as residential streets.
Slurry Seal is similar to Micro Surfacing except that it has a longer curing time. Slurry Seal will restore a uniform texture and friction loss on your pavement.
Fog Seal is an emulsion diluted with water that is sprayed immediately after a chip or scrub seal to help retain aggregate. It provides a black surface that helps with short term snow and ice melt off, and makes line striping more visible, enhancing safety. Fog sealing can be done with minimal traffic disruption and can help protect against oxidation on newer asphalt.
GSB-88, a restorative sealant containing a rejuvenating agent that is sprayed and immediately covered with sand, provides the introduction and reintroduction of oils and resins lost in the oxidation process, protecting against farther oxidation. It is Green Circle Certified and is one of the most environmentally sound pavement preservation products available, providing a virtually impermeable surface that protects against water intrusion. GSB-88 can be applied with minimal traffic disruption and is approved by the FAA.
High Friction Surface Treatments (HFST)
High friction surface treatments (HFST) dramatically and immediately reduce crashes, injuries, and fatalities associated with friction issues, such as:
- A reduction in pavement friction during wet conditions, and/or
- A high friction demand due to vehicle speed and/or roadway geometrics.
Pennsylvania, Kentucky and South Carolina DOTs report a before/after total crash reduction of 100 percent, 90 percent, and 57 percent, respectively, for their signature HFST trial projects.
