Potholes can form on asphalt pavement when water seeps below the surface and starts to freeze. The ice expands and causes the pavement to break up. Cars driving over the potholes can further damage the pavement, making the problem worse. Good thing, there is a way to repair these kinds of problems and that is through asphalt patching.
So what is asphalt patching? Read more as we’re going to talk about this method of asphalt repair in today’s post.
The Definition Of Asphalt Patching
Asphalt patching is the process of repairing potholes and other damages on an asphalt surface. This can be done by either filling the holes with a new material or by resurfacing the area. It is a necessary repair for any asphalt surface, as it helps to prevent further damage and keep the surface looking its best.
Types Of Asphalt Patching
There are several methods of asphalt patching, but the most common is to use hot mix asphalt. Hot mix asphalt is a type of asphalt that is heated to a high temperature and then mixed with an asphalt binder. This mix is then placed into the pothole or other repair area and compacted. As it cools, the hot mix asphalt hardens and forms a seamless repair.
Another method is called cold asphalt patching. It is a repair method that uses an asphalt emulsion and aggregate to fill potholes and other surface defects. The asphalt emulsion is a mixture of asphalt, water, and a surfactant. The surfactant helps to keep the asphalt in contact with the water and aggregate, which helps to form a stable bond between the components. Cold asphalt patching can be performed using a variety of equipment, including hand tools, wheelbarrows, or small dump trucks.
Other methods of asphalt patching include slurry patching and ultrathin overlay. slurry patching. This is a process that is very similar to asphalt patching. The main difference is that slurry patching uses a slurry mix instead of asphalt to fill in the hole. This mix is made up of gravel, sand, and cement. It is much more affordable than asphalt, and it can be used on a variety of surfaces including concrete and asphalt.
Slurry patching is a great option for those who need to quickly and easily fill in a hole. It is also much more durable than asphalt, so it will last longer. If you are looking for an affordable, easy to use, and durable option for patching a hole, then slurry patching is the way to go.
On the other hand, ultrathin overlay is a newer method that uses a very thin layer of asphalt to cover the repair area. This method is more expensive but can be used to make very seamless repairs. It is also very strong and can withstand heavy traffic. If you need to make a repair that will last, then ultrathin overlay is the best option.
There are several steps involved in ultrathin overlay patching:
- The first step is to remove the top layer of asphalt and any underlying material that is damaged or deteriorated. This can be done using a power grinder or a jackhammer.
- Once the surface has been prepared, the new asphalt layer can be installed. This is typically done using a paving machine.
- The new asphalt layer needs to be compacted so that it can provide a stable surface for vehicles to travel on. This can be done using a roller or a compactor machine.
- Finally, the patched area needs to be sealcoated in order to protect it from weathering and wear and tear.
No matter which method you choose, asphalt patching is a necessary part of maintaining your pavement. It can help to prevent further damage and keep your pavement looking its best.
How Long Does The Patching Last And What Is The Average Price
The length of time that asphalt patching will last depends on the type of material that is used, the weather conditions, and how well it is maintained. Hot mix patching usually lasts for several years, while cold mix usually only lasts for a few months. If the cold mix is not properly compacted, it may only last for a few weeks.
The average cost of asphalt patching can vary depending on the size of the repair, but typically runs between $50 and $100 per patch. Larger repairs can cost significantly more. For example, full-depth asphalt repair may cost $150 to $250 per square foot, while pothole patching may only cost $50 to $75 per square foot.
