Though asphalt is one of the most versatile, cost-effective, and popular paving materials, it does have a couple of drawbacks. There are a couple of things that can cause cracks in your paved surface. These include repeated salting, excessive precipitation, heavy snow and rain, extremely cold weather, seasonal changes, traffic, and more.
Your paving contractor can easily spot early indications of deterioration if you invest in a regular maintenance plan. This allows the contractor to fix minor issues on time. Regular maintenance and proactive investment of time will improve the lifespan of your asphalt pavement.
Though repairs will only fix minor wear and damages, any major deterioration will probably need a new installation of asphalt paving. There are a couple of factors that contractors consider before they choose between repaving or repairing your pavement. If you want to know more about it, visit www.gilbertasphalt.com.
Condition of the Base
You might have to resurface your asphalt pavement if the lower layers are still strong enough to support a new layer. Contractors will fill and fix the obvious potholes and cracks. Next, they’ll apply a new surface on top. This will help you achieve a new look at your pavement.
The pattern of cracks can provide you a sign of the level of damage to your pavement.
- Reflective or Longitudinal Cracks
The paved surface might establish linear cracks because of mediocre joint structures of traffic lanes. A professional contractor can apply a sealant to fix these cracks. Reflective cracks might present bigger problems that extend from the top surface to the foundation layer. Luckily, a professional contractor can fix them easily.
- Edge Cracks
Strong frost heaves, insufficient time for curing, or poor drainage can cause cracks at the edges of your parking lot or driveway. To tackle this issue, a contractor will get rid of the debris and overgrowth near the edges and seal the cracks using asphalt sealant.
- Block Cracks
Severe low temperatures or incorrect laying of the aggregate layers can cause the surface to establish huge square or rectangular-shaped cracks. A contractor can help fix these cracks.
- Alligator or Fatigue Cracks
This is the most common form of cracks in asphalt pavement. The common causes for this crack are insufficient foundation material, inadequate drainage, and harsh weather. The surface looks fractured and dry, just like alligator skin.
Labor and Effort Required
There will be times where the amount of time and effort needed to fix and patch surface cracks are too high for the contractor. That is why they will recommend replacement instead. This is particularly true if there are early indications of underlying problems. This can also occur if your pavement is already at the end of its expected lifespan. On these occasions, the paving contractor will recommend replacement rather than repairs.
Age of the Original Pavement
While almost every pavement lasts around 20 to 30 years, the amount of traffic and local weather conditions can shorten the lifespan of your asphalt pavement. With a simple resurfacing job, you can add 15 years. Unfortunately, it might be better to think about a new asphalt installation if your pavement is close to its expected lifespan.
