Chip Seal
Chip seal is usually applied with a fog seal afterwards – re-apply every 7 to 10 years. Soft, flexible, polymer modified asphalt emulsion. Seals the surface, including small surface cracks, to protect the road from oxidation (Seals most moderate width cracks for a few years). Keeps water from penetrating the road structure, protects the underlying base, stops the raveling of old pavement, and minimizes the effects of aging. Multiple layers can be applied to address severe cracking and raveling of oxidized/deteriorated pavements, as long as the subgrade is in good condition.
Multiple layers can be installed on prepared gravel surfaces to create a hard road surface and eliminate the need for dust control. Provides a highly skid-resistant surface. Minimum disruption during construction to the traveling public; road is kept open with one way traffic, controlled by flaggers.
Drawbacks: Loose gravel during construction; Needs to be swept a few times over the first winter.
Asphalt Rubber Chip Seal using Aggregate Pre-coated with Asphalt
Environmentally-friendly, durable asphalt rubber chip seal is made from paving grade asphalt, field mixed with approximately 20% recycled tire rubber. The rubber ingredient reduces reflective cracking, creating a flexible, strong surface.
- Re-apply every 8 to 12 years.
- Manages Alligator and Block Cracking.
- Reduce flushing and raveling.
- An aid to increase performance life.
- Save Money and resources in reduced prep work such as dig outs and crack fill.
- Soft, flexible, polymer modified paving grade asphalt.
- Seals the surface, to protect the road from oxidation.
- Keeps water from penetrating the road structure, protects the underlying base, stops the raveling of old pavement, and minimizes the effects of aging.
- Minimum disruption during construction to the Public; road is open with one-way traffic, controlled by flaggers.
- Flexible surface, with a faster curing time, so road can be swept within 30 minutes.
- Provides a highly skid-resistant surface, with minimum disruption to the travelling public; road is open with one-way traffic, controlled by flaggers.
Drawbacks: Higher initial cost, needs to be swept over the first winter, sensitive to humidity and areas of heavy shade during application.
Slurry Seal
Slurry Seal is produced in specially designed trucks, that carry the (unmixed) asphalt emulsion and aggregate. This material is blended together in a computer controlled, continuous-flow pugmill. Depending on the mix design, a small quantity of cement, lime, water and/or aluminum sulfate can be added to modify the physical properties. Augers mix and push the material into a drag box that squeegees the material evenly across the road. Traffic is not allowed until the water evaporates out of it, usually in 3 to 5 hours. This creates a durable, low cost maintenance treatment for roads, airport runways, & parking lots.
- Restores skid resistance.
- Improves color contrast between pavement and striping.
- Protects the structure from moisture intrusion.
- Protects the structure from oxidation.
- Maintains drainage patterns and curb reveal.
- Aesthetically pleasing, looks similar to HMA overlay.
- Good for residential streets and parking lots.
- Lower cost than a chip seal.
- Re-apply every 5 to 7 years.
Drawbacks: Road closures for 2 to 6 hours during construction, may need to be swept over the first winter, does not resist reflective cracking so cracks need to be sealed beforehand.
Micro-Surfacing
Micro-Surfacing is a variant of the slurry seal. Derived by mixing polymer-modified asphalt emulsion, aggregate, cement, mineral fillers & additives. Depending on the mix design, it can be proportioned and mixed as needed for various conditions, including night work, allowing the roads to be reopened to traffic, in some cases, within an hour.
- Increases skid resistance.
- Improves color contrast between pavement and striping.
- Restores surface characteristics.
- Protects the structure from moisture intrusion.
- Protects the structure from oxidation.
- Maintains drainage patterns and curb reveal.
- Restores road profile (within limitations).
- Resistant to rutting and shoving.
- Aesthetically pleasing, looks similar to HMA overlay.
- Used on private roads, local streets, arterials, busy intersections, interstate highways, airports, taxiways, & parking lots.
- Good for rut filling, surface profiling, heavier traffic.
- Can be used in multiple lifts.
- Re-apply every 6 to 8 years.
Drawbacks: Road closures for 1 to 4 hours during construction, may need to be swept over the first winter, does not resist reflective cracking so cracks need to be sealed beforehand.
Crack Seal
- As a stand-alone treatment, it could add an extra year or two before resurfacing is needed.
- Slurry seal & micro-surfacing may need crack sealing on existing cracks, to avoid reflective cracking.
- Chip seal will seal the small surface cracks, but crack sealing the medium to wide cracks beforehand is recommended.
Cape Seal
A combination of maintenance treatments may be most cost-effective.
Cape seal is a slurry seal or micro-surface on top of any chip seal. Chip seal would be an interlayer; this option is recommended when the existing road has deteriorated or cracked too much, and needs the flexibility that a chip seal interlayer provides, along with the smoother top surface from a slurry or micro. Aesthetically pleasing, looks similar to HMA overlay. Not as expensive as some might think, since fog seal is no longer needed, saving $0.50 to $0.65 per square yard.
Chip Seal Patching
If portions of the road have deteriorated too far to be saved by a single chip seal or slurry seal, a chip seal patch, with a full width seal afterwards, is the most cost-effective way to preserve the asphalt pavement. In most cases, chip seal patches perform just as well as hot mix asphalt (HMA) repairs, at a fraction of the cost. This also eliminates the need for crack seal.
The extra layer adds body and strength to the road, bridging over cracks, while remaining flexible. It seals the surface, including moderate to severely deteriorated and cracked roads. If the road has a good subgrade, this new surface will last until the next normal maintenance cycle.
Double Chip Seal
Double Chip Seal is needed when the road has deteriorated too far to be saved by other methods.
- Extremely durable and flexible surface.
- Keeps water from penetrating the road structure and stops the cracking & raveling of old pavement.
- Seals the surface, including moderate to severely deteriorated and cracked roads.
- Provides a highly skid-resistant surface.
- Minimum disruption to the traveling public; road stays open during construction with one way traffic, controlled by flaggers. If the road has a good subgrade, this new surface will last for years, until the next normal maintenance cycle.
- Re-apply with a single chip seal after 8 to 12 years. See the Case Studies page for performance reports on this.
