ASPHALT OVERLAY

Asphalt overlay is a vital asphalt paving service provided by asphalt laying contractors and companies. These asphalt paving services involve repairing a deteriorating surface, rather than asphalt laying a new surface altogether. Asphalt laying contractors would like to first assess the surface, to verify that an overlay is the correct method of repair. Some more deeply damaged surfaces will need to be completely ripped up and resurfaced. If an overlay is the right solution, asphalt laying contractors or companies will then use an asphalt milling machine to remove the damaged surface, to ensure that the new layer will create a smooth and adequately bonded surface. After removing the damaged layer properly, asphalt laying contractors or companies will then pave the area using asphalt overlay, to the required thickness needed to create a smooth and precise patch.

USING ASPHALT OVERLAY ON CONCRETE

In some cases, concrete that is in disrepair can be fixed using a similar method. These asphalt paving services can be much more cost-efficient than ripping up and relaying an entire concrete surface. However, it is only possible in certain situations. Asphalt laying contractors or companies will inspect the concrete surface and determine whether an asphalt overlay is the correct method of repair. If the asphalt laying contractors or companies decide that this is, in fact, the right method, they will repeat the above process, with an additional step to cut expansion joints into the surface to avoid cracking or other complications due to seasonal expansion.

ASPHALT POTHOLE REPAIR

Over time, asphalt covering streets and roads ages and becomes damaged due to a constant pounding by traffic and weather. It is vital that the asphalt laying services of asphalt laying contractors and companies are enlisted in the early stages of disrepair, to ensure that the damage does not increase to the border at which it is no longer cost-effective to repair. When surfaces can remain unmaintained for an increased period, potholes will likely appear. Asphalt laying contractors or companies will fix a pothole using one of two asphalt paving services. These two asphalt paving services are full-depth, and surface patches. A full-depth patch is a near-permanent solution, while a surface-level patch is a temporary solution that prevents water from entering the damaged area, causing a more serious and expensive problem to fix.

ASPHALT SURFACE PATCHING

The more temporary asphalt paving services that asphalt laying contractors or companies may employ involves the following. The pavement is milled to an appropriate depth determined by asphalt laying contractors or companies at which all the damaged material removed. At this point hot mix asphalt will be mixed and laid by asphalt laying contractors or companies to patch the surface, tying it to the surrounding surface, and temporarily patching the surface, and preventing water from entering the damaged area. This temporary fix will eventually be replaced with a full-depth patch.

FULL-DEPTH PATCHING

Full-depth patching is an asphalt paving service provided by asphalt laying contracts or companies which is a permanent solution to fix a pothole in a worn road or street surface. For a start, asphalt laying contractors or companies will excavate ground until an appropriate depth where firm support can be created. At this depth, it is likely that sub-grade gets removed, and in some cases, drainage installed. Once asphalt laying contractors or companies remove the ground until the correct depth, asphalt tack coast should be applied for maximum support. A full-depth patch works best when filled with dense-graded hot mix asphalt, cold mix, specialty mix, or a proprietary mix. It is important that asphalt laying contractors or companies overfills the area, as constant traffic use will compact the material down over time.

POTHOLE PREVENTION

While pothole repair is a standard asphalt paving service provided by asphalt laying contractors or companies, it is more cost-effective to repair road surfaces when they are in fair to good condition, preventing the inception of potholes in the first place. Sealing cracks that appear on the road surface are the most efficient way to maintain asphalt and avoid further damage. These cracks should be filled by asphalt laying contractors or companies in the middle of their opening range, usually in the spring or fall, to ensure that it is neither over, or underfilled during the summer and winter months. Asphalt laying contractors or companies will repair cracks in road surfaces depending on their width and depth. Cracks smaller than ¾ inches will only require cleaning and filling using either fog, chip, slurry, or sand sealant by asphalt laying contractors or companies. If the crack is more significant than ¾ inches, it is more severe and will, therefore, require filling with hot mix asphalt, hot poured sealant, or emulsion slurry sealant. In all cases, the crack will need to be cleaned by asphalt laying contractors or companies using high-pressure water/air, hot air blasting, or sandblasting. This cleaning will ensure that a firm bond is formed, preventing further damage or cracking from occurring.

ASPHALT RESURFACING

Another common asphalt paving service provided by asphalt laying contractors or companies is asphalt resurfacing. Though patching and repairing surfaces can be efficient, eventually road surfaces require complete resurfacing. A resurface will often last 8-12 years with proper maintenance, making it long-term, but not permanent. Before any work can begin on resurfacing, asphalt laying contractors or companies must ensure that any utilities underground is safely lowered out of the way to make sure that they are not damaged by the milling that must take place when resurfacing an area. Once this has taken place, asphalt laying contractors or companies will start to remove all debris from the required field and begin to mill away the old surface using a milling machine. After the milling is complete to the desired depth, the utilities mentioned above are brought back up to their original level when the new asphalt surface laid. It is essential that throughout this process, asphalt laying contractors or companies take steps to ensure that water runs off correctly, preventing damage in the future. Asphalt laying contractors or companies will use laser-guided transits and roll tests to ensure that a proper grade achieved. Without an appropriate degree, water will likely cause damage to the surface, resulting in cracks and potholes, and expensive repairs early and often.

The next step asphalt laying contractors or companies will carry out is to put a thin coating of asphalt or tar using a distributor truck which allows forming a strong bond between the existing surface and the new layer of asphalt. This sub-base is extremely important in ensuring that the surface is stable, as well as able to survive extreme weather conditions with minimal damage. After this binding agent has appropriately set, a new layer of asphalt, made of hot mix asphalt, can be poured and rolled flat by a rolling truck to create a smooth ride for traffic. Because it is highly uncommon for a new asphalt surface to be poured entirely independent of other surfaces, it is essential that asphalt laying contractors or companies properly bond and levels the new surface with existing surfaces. Once the final touches including road striping and reflectors applied to the surface, the new asphalt road is ready for testing and approval and finally used by traffic.

SAFETY

Throughout all these services, it is of paramount importance that asphalt laying contractors or companies correctly segments off, and place signs warning that works are going on the road to avoid any safety hazards to both drivers and workers. Though the primary job of asphalt laying contractors or companies is to provide asphalt paving services, they also must ensure that all the functions carried safely and efficiently.

Asphalt Repair

Asphalt repair is a cost-effective way to maintain asphalt surfaces. As opposed to completely tearing up and resurfacing an area, asphalt repair merely involves patching an affected area. Asphalt repair companies can hire other contractors who offer such asphalt repair services. This article will explore the ways asphalt repair companies and their contractors perform different asphalt repair services to fit a variety of situations.

WHEN TO REPAIR

Contractors, asphalt repair companies will determine if repairing a surface is the most efficient means of maintaining it. In most cases, cracks of various sizes and potholes can be filled merely and bonded to the existing asphalt. That once again creates a smooth surface for traffic. Asphalt repair companies, repair contractors use a variety of tools to carry out these asphalt repair services. New asphalt surfaces that have proper maintenance usually have a lifespan of up to 12 years before they need a replacement. If the surface is not maintained correctly by asphalt repair companies, the lifespan of the asphalt is much shorter, resulting in the need for replacement. Hiring asphalt repair companies to sustain asphalt surfaces makes the lifespan of the road longer and more cost-effective in the long run. Asphalt repair companies and their contractors offer asphalt repair services such as asphalt overlay, surface patching, full-depth patching, milling, and resurfacing. These services ranged in their intensity, intrusion, and expected longevity of the repair itself.

SMALL ASPHALT REPAIRS

Often, the asphalt repair services which asphalt repair companies need to perform are relatively small and minimally invasive. One of the most regular asphalt repair services that asphalt repair companies or contractors may perform is asphalt resurfacing. That is often a temporary fix for minor issues, but it is cost-effective. Asphalt resurfacing can also help prevent further damage to an area until a more permanent solution introduced. When patching the surface, asphalt repair companies or contractors will mill the damaged area down to an appropriate level, before cleaning the area and laying down hot mix asphalt. That repair can be useful on potholes in high traffic areas which need to be patched promptly to ensure that traffic can continue safely through the area. For the most part, asphalt resurfacing will prevent water from getting into the damaged area, which will cause the damage to increase, and in turn, create a costlier repair by asphalt repair companies down the line.

Smaller cracks in asphalt surfaces are often repairing with a sealant. That involves asphalt repair companies, contractors cleaning the affected area of any debris, before filling the crack with chip seal, fog or slurry mix, or sand sealant. Such asphalt repair services should be better performed by asphalt repair companies in the fall or the spring, as this is when the cracks are in the middle of their opening range. If this crack sealing performed during the summer, it is likely that the seal crush during wintertime when the crack compresses. Similarly, if asphalt repair services performed during the winter, the crack may fall in during the summertime, when the break expands and widens. Minor asphalt repair services such as the ones outlined above are essential to the maintenance of asphalt surfaces. Asphalt repair companies and their contractors should routinely check up on asphalt surfaces and perform these services, as they will prevent more severe damage from occurring, resulting in more severe asphalt repair works.

MAJOR ASPHALT REPAIRS

Inevitably, the more severe damage will occur to asphalt surfaces over their lifetime. In these instances, asphalt repair companies and contractors will perform more permanent asphalt repair services to ensure that the surface is quickly back to working order. For example, a severe pothole fixed with a method called a full-depth patch. These asphalt repair services will last significantly longer than a surface patch and will ensure that no further damage occurs in the affected area. While performing a full-depth patch, asphalt repair companies and contractors will mill the area, of the pothole to allow for steady support to be created. Firm support usually requires a depth of at least 4 inches below the surface. This support is the main difference between a surface and a full-depth repair. In some more extreme cases, the depth required to create firm support is so high that new drainage will be necessary. Once the support ready, asphalt repair companies will make a tack layer, and this is a sticky tar layer that allows better adhesion between the surface and the new layer of asphalt. After the tacking layer, asphalt repair companies will add the hot asphalt mix. The final touch for a full-depth patch is a backfill layer over top of it to bond the patch with the surrounding asphalt. It is essential that asphalt repair companies overfill the patch to account for compaction from constant traffic usage. If the asphalt repair companies or contractors do not intentionally overfill it, it is likely that the patch will be compacted back into itself, creating an uneven, and slippery surface.

For more severe cracks in asphalt surfaces, asphalt repair companies will likely use asphalt repair services that utilize hot mix asphalt, emulsion slurry sealant, or hot-poured sealant to fill the crack. If the break is more in-depth than 2 inches, a backer rod must be installed. A backer rod conserves sealant as well as ensuring a tight bind. The area should be thoroughly cleaned and cleared of all debris by asphalt repair companies or contractors before performing any asphalt repair services.

In some cases, asphalt repair companies will determine that an asphalt overlay is a correct repair to perform on a damaged area. Asphalt repair services such as these are also known as asphalt peel and paving repairs. Asphalt repair companies will first identify and mark out the damaged area of the asphalt. Asphalt repair companies or contractors will then use a saw to cut the pavement, allowing the damaged area to be peeled up. The damaged area is milled down all the way to the sub-base to allow complete replacement. After ensuring that the sub base is still strong enough to take the weight of the traffic that will be using it every day, asphalt repair companies will then begin to pour the new asphalt. With asphalt repair services like the peel and pave method, it is crucial that asphalt repair companies remove all the damaged asphalt. Failing to remove all the damaged asphalt pieces can result in an unstable bind, causing further damage to the new and existing laying. That ultimately leads to more expensive asphalt repair services having to be performed by asphalt repair companies or contractors down the line.

When asphalt repair companies or contractors are performing these more major asphalt repair services, it is essential that one should check the gradation along the way. Asphalt repair companies have a variety of tools at their disposal to accomplish this. Laser-guided transits, as well as roll tests, ensure that an even grade achieved throughout the repair. By utilizing these tools, asphalt repair companies provide that a new level bonds with the existing asphalt layer. A quality repair will also ensure that water will drain properly from the area, preventing further damage from occurring sooner than natural.

Safety is also a concern for asphalt repair services. Asphalt repair companies should take the appropriate precautions to insure that work areas are appropriately signed and detached from the public to keep both motorists, and workers safe.

SUMMARY ABOUT ASPHALT REPAIR

In summation, asphalt repair companies and their contractors should be utilized to check up on asphalt surfaces periodically and to perform asphalt repair services. The conducted minor costs for asphalt repair services will pay off in the long run, as asphalt repair services companies ensure that the surface will be able to be used for its entire lifetime of up to 12 years. In most cases, asphalt repair companies offer plans which include maintenance for a more cost-effective approach to keeping traffic running smoothly, and safely.

Guardrail Installation & Repair

Guardrails are essential safety features in a variety of commercial and residential settings. They are most often used to help prevent people or vehicles from going off roads, paths, walkways, etc. into dangerous terrain or areas. Some guardrails are designed to restrict or deter cars or people from physically going through them, whereas others are more cautionary, high-visibility devices that wouldn’t hold up under strain. Regardless of the setting and type of guardrail involved, the experts who design, build, and maintain guardrails for commercial and residential clients are known as guardrail construction services or guardrail installation and repair services. These companies may focus on specific categories of customers or materials, individual styles of guard rails, and may have expertise in certain types of guardrail installations.
