7 Signs That Your Asphalt Pavement Is Failing
- 3 reads
Asphalt is one of the most popular paving materials and is commonly used for roads and parking lots. Asphalt is durable, flexible, and a resilient material which makes it a good choice for commercial uses. However, unlike everything asphalt is also prone to damage. Regular wear and tear can cause chipping and cracking so you would need to conduct a patch repair, seal coat the pavement to prevent staining and discoloration, hire service for snow removal in Denver to avoid snow-related damages to the asphalt. There are several ways to prevent your asphalt pavement from damage.
Without proper care and maintenance, the asphalt pavement can fail and perform poorly. You need to keep an eye out to check if there are any signs of damage. There are a couple of signs that indicate that the asphalt is failing and needs repair. The following are some signs to look out for.
Raveling is the condition when the aggregate particles in your asphalt pavement start to wear away. This usually happens due to heavy traffic in the area. Raveling suggests that either a poor-quality aggregate was used in the mixture or that the pavement has become lost its flexibility and become hardened enough to chip away due to heavy stress. When you notice this, happening get it repaired to prevent further damage.
These cracks appear in the shape of a crescent and hence the name. This happens when the raw materials in the mixture have slipped beneath the underlying layer and happen when there isn’t a proper bonding between the layers. The lack of bonding can also be due to dirt, grease, oil, and other contaminants preventing adhesion between the layers. In the case of slippage cracks, all the sections containing these cracks will need to be removed and require a full-depth patch repair.
Undermining happens when a pipeline beneath the surface of the pavement has cracked, burst, or become loose from the drainage structure. The cracks then begin to allow soil from the above layer to pass through them until the entire asphalt surface above has undermined. In such a case, you would need to hire a professional contractor to dig down to the problem area fix the plumbing issue, and then replace the damaged base and the asphalt.
Without proper drainage, the asphalt pavement will fail much quicker. A good contractor will always make sure that the drainage is in good condition before laying the asphalt layer. If there isn’t proper drainage then the water from rain or melted ice will accumulate on the pavement layer and the moisture will slowly percolate below the surface causing disruption in the layer below the surface and damage to the binding agents as well.
Alligator cracks are quite common in asphalt pavements and they resemble the scales of the alligator which is why they are named so. These cracks can be confined to a particular section or become a widespread issue. Alligator cracks are a sign that the foundation beneath the surface of the pavement is deteriorating and is susceptible to cause lasting damage. If you notice alligator cracks in your parking lot then immediately hire a Denver asphalt repair service to get it fixed.
Ruts And Depressions
When the subgrade layer is weak, the asphalt mix is insatiable, poor compaction, and inadequate thickness of the pavement leads to rutting. It occurs in the wheel path and is a linear depression. Depression, on the other hand, is localized to specific areas of the pavement and undermines the asphalt layer in the area. Rutting and depressions if not repaired in time can lead to pothole formation.
Potholes are circular holes in the pavement surface caused by localized failure of the asphalt pavement. Potholes can be caused by patch failures, cracks, segregation, insufficient compaction, etc. weak spots and damages in the asphalt surface can eventually lead to pothole formation if not tended in time.
