Potholes in driveways are a common problem for property owners. Any driveway can be affected, and if pothole repair isn’t performed promptly, many further problems can arise, including safety issues and possible legal troubles. Understanding how potholes form and what can be done to both prevent and fix them will save you time, money, and frustration.
Potholes occur when water seeps into cracks in the pavement, eroding the ground beneath. Due to temperature drops, the ground expands, pushing the pavement up. When the temperature increases and the ground returns to its normal level, the pavement remains raised, leading to a gap between the pavement and the ground. When a car drives over the gap, the pavement cracks and a pothole forms.
Asphalt Patching Methods to Get Rid of Potholes in Your Driveway
When it comes to asphalt, temporary delays to the repair of apparently minor issues, such as potholes and other types of asphalt damage, often result in the further degradation of both the surface and the subgrade.
Asphalt material is similar to what you see road crews laying on roads.
Moreover, hot mix asphalt is an aggregate of stone along with a slurry of asphalt, a tar-like material made from petroleum.
Then, it’s important to heat the asphalt above 300 F to liquefy it.
When correctly implemented, asphalt is better for overall driveability, appearance, your budget, and the environment.
Here, in this blog, we’ll discuss everything about different types of Asphalt Patching Methods.
Long-Lasting Pothole Patching Methods
There are different asphalt problems you may see on your own driveway. This means that all types of asphalt problems need a specific kind of repair method.
Knowing what type of asphalt problem you have would lead you to know which types of Asphalt Paving Toronto services you would need.
After determining this, you would know which equipment, technique, and materials are suitable to correct the issue.
Here are some of the generally used Pothole Patching Methods:
Among the most common asphalt patching techniques is the throw-&-roll pothole repair method.
This is a temporary patching technique in which contractors pour liquid asphalt into the pothole.
And once filled, the asphalt contractors will seal the pothole and roll over it.
The throw-and-roll method is typically performed during emergency situations in which you need an immediate patch for short-term use only.
Further, the application of this type of patch is in layers to ensure a complete fill.
#2: SEMI-PERMANENT PATCHING
A long-lasting alternative to the throw-and-roll is the semi-permanent pothole repair method.
While it is not permanent, the method does provide fast restoration to damaged asphalt.
Further, the semi-permanent method requires adequate preparation of the surface through the removal of water and debris within and around the pothole.
Once the workers cut the area around the pothole, they pour the patching materials into the prepared hole and compact the area using a vibratory roller.
#3: SPRAY INJECTION
Another familiar asphalt patching technique is the spray injection pothole repair method.
While this technique is similar to the semi-permanent method, the spray injection method requires specialized Pothole Patching Machine to remove water and debris from the pothole.
The aggregate and asphalt are then placed into the hole using high-pressure injection.
One key benefit of this technique is that it doesn’t require compaction commonly required for other methods.
#4: FULL-DEPTH PATCHING
The full-depth patching method is the pavement industry-standard technique for permanently repairing asphalt issues, such as potholes, among professional asphalt paving contractors.
This method provides firm support through the excavation of four or more inches in-depth and at least one foot of the areas around the pothole.
Further, before the contractors pour the asphalt mix into the depression, they apply a tack coat.
Contractors apply a backfill to the patching area to ensure proper bonding of the materials to the surface.
