Whether you have an asphalt driveway or an entire parking lot to maintain, asphalt pavement is a durable option. However, there are many dangers to your pavement, leading to severe damage. Sealcoating protects your pavement from many threats. Check out these three benefits of sealcoating your pavement.
Sealcoating Slows the Oxidation Process
One of the reasons asphalt is such an amazing material for roads, parking lots and driveways is its flexibility. While not enough to see with the naked eye, asphalt bends under the weight of vehicles. This prevents it from cracking when under pressure. The reason for this flexibility is instability. The asphalt is unstable on a molecular level. However, naturally, the molecules try to find a stable state, which would make the asphalt rigid and more likely to break under cars. This is called oxidation, but sealcoating adds a new layer of fresh asphalt, starting the entire oxidation process all over again, reducing the risk of cracks.
It Protects Against Corrosive Liquids
A common threat to asphalt is corrosive liquids like oil. Cars leaking these liquids can cause the asphalt to break down. Again, this affects the asphalt on a deeper level, actually causing the rocks in the asphalt to become loose and unable to stay together. This leads to potholes and deterioration as the asphalt simply crumbles to pieces. Occasional sealcoating can protect your asphalt by covering up these corroded spots. However, if your parking lot or driveway has poor drainage, you'll need to correct that too. Contaminated water can cause asphalt to break down even faster, making sealcoating a waste of money.
It Reduces Damage From Weather
Even the weather is fighting to destroy your asphalt parking lot or driveway. In areas with frequent rainfall, you need to be mindful of cracks. Water can seep into cracks and reach the ground below the asphalt, causing sinkholes and increasing the risk of more cracks. If the water freezes while in cracks, it can make them bigger. During the summer, the UV rays from the sun can also cause damage. They cause your asphalt to age faster, leading to fading and frequent cracking. Sealcoating will undo this damage, giving your asphalt a new surface layer.
Asphalt is an extremely excellent material because of its strength and flexibility. However, over time, age, corrosion, and the weather can ruin your asphalt. For more information about sealcoating or paving, contact a paving company like Arrow Blacktop & Masonry Inc in your area today.Share
