Have you started to notice that your driveway’s asphalt surface has a lot of potholes and cracks? If your answer is yes, then it may be time for you to replace the pavement.
Unfortunately, even with the best maintenance, nothing lasts forever. Harsh weather conditions, UV rays, freeze-thaw cycles, and heavy traffic are all factors that can shorten the lifespan of asphalt pavement. That’s why it’s important that you always keep an eye on your driveway or parking lot’s condition.
Here are 7 big signs you may need to replace your asphalt surface.
1. Alligator Cracking
Is the surface of your asphalt pavement starting to look like an alligator’s hide? Make sure that you take a closer look at the patterns of the cracks on the surface of your parking lot or driveway.
If these cracks take on a scale pattern, then you may want to consider completely replacing the asphalt. Known as alligator cracking, this is usually a sign of foundation failure.
2. Large Potholes
It’s easy to fill minor potholes here and there to give your driveway or parking lot a quick facelift. However, if any pothole grows big enough, it increases the likelihood of water being able to penetrate the foundation. If this happens, the foundation of your pavement will weaken and fail.
Deep potholes are dangerous because they can cause a lot of potential damage to vehicles. Additionally, they pose tripping hazards for pedestrians.
3. Buckling and warping
Examine the pavement’s surface. Is the asphalt level and even, or do you perceive wavy sections? Warped pavement can occur as a result of an insufficient or damaged base, as well as intensive vehicle use.
Often, asphalt can be used to level the ground. On the other hand, both the asphalt and the base may need to be replaced at times.
4. Drainage Problems
One of the most serious risks to healthy pavement is lingering dampness, which can infiltrate between layers and disrupt the binding agents. If you find puddles in your driveway or parking lot, talk to a contractor about parking lot drainage.
The likelihood of cracks, potholes, and other damage is reduced by leveling these problem regions.
5. Discolored Color
Sunlight and frequent use might fade your black pavement to gray over time. Because of its brittleness, older pavement is more prone to cracking.
Strategic repairs and regular seal coating can keep this fading pavement from deteriorating further.
Crushed stone or a compacted base underpins asphalt pavement. Sinkage may occur if this base begins to deteriorate, particularly near buildings and other structures such as carports.
Sinkage frequently indicates that your downspouts are depositing water too close to the structure, which increases the effect on the pavement below. In addition to asphalt treatments, you may want gutter repair.
Chemicals, such as automobile fluids and industrial solvents, can chip away at the asphalt binding agents. Speak with a contractor if you see a chemical spill or discoloration.
Until these spills are treated, they will continue to sink into the pavement and spread outward.
