Asphalt Patching / Pothole Repair
The best way to protect the investment in your asphalt pavement is to be diligent about “preventative” maintenance such as crack filling and seal coating. Be careful with your observations because once asphalt decay issues have advanced past the stage for simple and less costly maintenance, a “reactionary”, and the most costly solution may be your only choice. Asphalt patching becomes very necessary asphalt maintenance for areas that heavily cracked (or looking resembling a surface that appears “alligatored”), sunken or dropped below grade, weather-exposed and decayed due to repeated freezing and thawing (resulting in potholes), or asphalt that is raised organically by tree roots or underlying water damage.
The perimeter of the affected area will be saw-cut to provide a clean, professional-looking edge, and to provide maximum structural integrity. All cuts will be made at least 12-18″ outside of the visible surface damage because most damage starts underneath, working itself upward and showing itself at the surface last. If the area is too small, there can soon be new damage around the perimeter of a new patch.
Old, weathered, damaged, and decayed asphalt will be milled (removed) and disposed of, but most likely, it will be recycled; asphalt is the most recycled material in the world. The asphalt sub-base or native soil will be inspected, and the appropriate maintenance action will be taken which may include: pruning back tree roots, introducing new crushed rock, or providing additional compaction on the base or sub-base. The new hot mix will then be placed and compacted. Tar seal is then applied to the asphalt seams (between old adjacent to new) to prevent moisture penetration. By most asphalt standards, the actual asphalt thickness (not including base and sub-base) should never be less than 2 inches. Areas that heavy traffic loads including high traffic volume on the asphalt application will require a greater thickness.
Asphalt Crack Fill
Moisture penetration into asphalt through small cracks is not only the most common symptom of asphalt damage and decay but easily, most cost-effectively remedied. Cracks typically start small as a direct result of an organic freeze-thaw cycle. Then, as moisture penetrates through these cracks and gets underneath the asphalt layer, it begins to disturb the subgrade layer and can quickly cause more widespread damage.
Team Cam is very effective at crack filling because we recognize that it begins with properly cleaning out the cracks of moss, dirt, debris, etc. We use wire brooms, rotating bristle heads and blowers for this purpose. Team Cam then uses a hot-apply, rubberized crack filler to fill in the exposed cracks; a method found to be superior to cold-apply products. The material is heated, poured into the cracks, and then torched to ensure a proper bond and surface smoothness. The crack filler then cools, hardening inside the crack, preventing any additional moisture penetration.
Asphalt Seal Coating
When asphalt is freshly paved, it has a rich, black color. As the asphalt ages and is exposed to the elements, asphalt will progressively become grayer and grayer and the texture will become courser and courser. This is the result of gradual decay to the liquid asphalt that serves as the binder in asphalt pavement. Sealing asphalt periodically serves two mutually beneficially purposes: it will restore the rich black color which is aesthetically pleasing, and it will restore the binder which promotes the structural integrity of the asphalt pavement.
Asphalt sealing is one of the oldest services in our company, and we have a lot of experience. The Team Cam asphalt management team is well-versed at minimizing the inconvenience of:
- Prime-time barricading and traffic re-direction
- Extended site preparation and coordination
- Giving up all or parts of your parking lot for extended prime-time
Team Cam uses a quality and regionally-renowned sealers, and we understand how proper dilution ratios will affect the longevity of your seal. The cost of sealing the asphalt surfaces every 3-7 years is much less costly than totally replacing cracked and damaged asphalt.
The most common kind of speed bumps installed are asphalt speed bumps. These types of speed bumps are extremely effective, very durable, and to keep them looking fresh and noticeable, asphalt speed bumps repainted and can be resealed annually.
Asphalt speed bumps, like the kind that Team Cam installations are typically found in parking lots to serve the purpose of reducing vehicle traffic speeds to 10 to 15 mile per hour. Although concrete speed bumps are expensive to install, as a permanent fixture they are difficult to remove or damage, unlike plastic or rubber speed bumps.
Asphalt speed bumps are primarily used to reduce traffic speeds which also reduces traffic volume in parking lots and on streets and residential thoroughfares. Typically, they are most effective at slowing traffic in residential communities—where families and children play—commercial and retail parking lots, and commercial and private driveways.
Team Cam asphalt speed bump installations and projects include design, speed bump placement, and installation or repairs after the speed bumps have been in service. They can also remove, reseal, and repaint any speed bumps which are not performing or have become damaged over time.
