- Asphalt is frequently used as a paving material because of its cost-effectiveness and durability. Its ability to withstand heavy loads and longevity is the reason it is used in parking lots and driveways. A combination of yearly inspections, crack filling and sealcoating maintenance will maximize the lifetime of asphalt surfaces. Our staff and crews can manage your job from initial evaluation and consultation, right through design, installation, and preventive maintenance.
- Asphalt Patching
- The least expensive and least intrusive option for repairing this type of hazard is to fill the holes using hot mix asphalt, and seal the edges to prevent water penetration. Hot mix asphalt patch represents a temporary fix and its lifetime will depend on traffic and use.
- Asphalt Resurfacing
- Resurfacing is installing a layer of asphalt over an existing asphalt area. Resurfacing gives your parking lot or roadway the look and feel of new pavement; it can also extend the lifespan of the pavement without the expense and inconvenience of removing and replacing the entire area.
Asphalt resurfacing is not always a viable option. In situations such as significant structural deterioration, an inadequate sub-base, poor drainage conditions, or areas that have been resurfaced several times previously, resurfacing may not be advisable. In other cases, resurfacing should only be recommended when combined with options such as milling or grinding, or the addition of geo-textile fabric, or full-depth repairs. After a careful evaluation of your existing pavement, our experts will recommend the best options for your situation.
- Catch Basins
- Catch basins, also often called "storm basins," collect drainage in paved areas. Often, existing catch basins will need adjustments to ensuring storm water and melting ice drain away quickly yet maintain a smooth driving surface around basins.
- Crack Filling
A crack sealant is the first barrier against pavement deterioration. Commercial grade rubberized crack sealant keeps water from entering the pavement, preventing weakening of the base or sub-base. It also prevents dirt and sand from working their way into the open cracks, which can lead to compressive stresses on the pavement. When rubberized crackfiller is used in combination with sealcoating maintenance, crack-filling slows the progression of any cracks and extends the longevity of the pavement.
Regardless of the cause, cracks will allow water to penetrate the surface and erode the base material, requiring costly, full depth repairs or full replacement. Effective crack-filling helps prevent water, sand, and other debris from entering the cracks and causing stresses.
- Full Depth Repair
- A full depth repair is necessary when a failed area cannot be fixed with general maintenance options. A full depth repair requires removing all asphalt in the failing areas to the sub-base. If the sub-base is found to be soft, the area will be undercut until a solid base is found. Aggregate is installed and the asphalt replaced. We suggest that if 25% or more of your parking area requires full depth repair, you should consider a total replacement. There are many reasons for asphalt to fail at this level and some are unavoidable. However, full depth repairs can be minimized with a general maintenance plan. Annual inspections and periodic patching of your asphalt surface will prevent serious deterioration and the need for full depth repairs.
- Partial Depth Repair
- A partial depth repair involves milling or grinding off the top 2â3 inches of asphalt, replacing it with new compacted asphalt, and sealing the edges. Although a partial depth repair is more costly, it is a considerably less expensive option than a full depth repair and can be performed in half the time. Partial depth repair is only feasible when the deterioration occurs only in the surface layer of asphalt. It is not suggested when problems are caused by a sub-base failure. One benefit of a partial depth repair rather than patching is the edges and grade match the surrounding asphalt, which eliminates raveling edges.
- Pavement Marking
- First impressions are crucial for every organization. Parking lots should be attractive and safe for tenants and visitors. An expertly striped lot will direct and enhance the flow of traffic and guide pedestrians through the area safely. Beltway Paving has many years of experience in pavement marking. It not only improves traffic flow and enhances pedestrian safety, but we offer a variety of design options that will maximize your lot's space utilization.
Sealcoating is vital to the success of any asphalt maintenance program. It seals out harmful elements like water, which turns to ice and promotes cracking, salt and gasoline and oil products eat away at pavement oils. It also protects pavement against sun damage. With any asphalt pavement, oxidation occurs over time causing a grayish color and causes the surface of the asphalt parking lot to become dry and brittle. This will lead to the erosion of the small particles on the surface, leaving small cracks and larger stones. Left untreated, the result will be larger cracks and potholes that allow water to penetrate the asphalt, causing base failure and requiring costly repairs.
Sealcoating is a protective coating over existing asphalt with squeegee or spray wand. Seal coating is designed to slow the oxidation process, and it provides a fresh, clean surface that is visually appealing and allows for ease of sweeping. The ASMA (Asphalt Sealcoat Manufacturers Association) recommends that new pavement be sealed from 6 to 12 months after installation and every 2 to 3 years afterwards as necessary.
- Surface Patching
Surface patching involves installing 1â2 inches of asphalt in designated failing areas of the parking lot. It is similar to resurfacing but on a smaller scale. The asphalt is installed with an asphalt paver and compacted much like the installation of the original parking lot. This option is often suggested for areas that are cracking but not crumbling.
Although a surface patch will help prevent water from further penetrating the asphalt, it is only a temporary fix, with an estimated lifetime of approximately two years, depending on traffic. The edges of the patch are tapered to the original asphalt and are subject to abuse by snowplows and general traffic. To eliminate the risks associated with raised pavement, a partial depth repair is recommended.
