Asphalt is one of the most popular types of paving that is both affordable and durable. Even so, it can wear down over time due to the constant exposure to ice, rainwater, and heat from the sun. The effects can either be distortion, disintegration, or cracking. You should be more worried about cracks than any of the mentioned damages because they are the leading cause of potholes.
However, further damage can only affect your paving if you don't hire crack sealing services. As such, you might need to learn some common types of asphalt cracking so that you can take timely action. Here are common types of asphalt cracks you probably don't know about.
1. Longitudinal Cracks
Longitudinal cracks are long cracks that occur at the center of the pavement and are common in permafrost regions. They are self-induced and can extend several meters. The best solution to this kind is crack sealing and filling. If you notice this kind, contact a paving contractor right away.
2. Alligator Cracks
Alligator cracks are also commonly known as fatigue cracks or spider-webbed cracks. Unlike longitudinal cracks, the alligator type does not happen from within but rather externally. They occur due to weight from heavy vehicles, especially trucks. So if you deal with heavy vehicles, you will most likely notice these cracks. They look like spider webs due to the interconnections, and they extend to the foundation.
Alligator cracking moves in levels. There is a minimal level which is showcased by mildly connected parallel cracks. If not attended, they create notable patterns with some spalling in some cases. The most significant cracking is shown by very visible spalling that moves when a truck drives through. Crack sealing can prevent further deterioration, but your asphalt contractor might recommend repaving.
3. Block Cracks
There is no spalling for block cracks, but you will notice rectangular shapes of about one foot long on various parts of your pavement. They are not caused by weight from heavy tracks but rather shrinkage and fluctuating temperatures. The effects cause the asphalt to harden and later break into blocks.
4. Slippage Cracks
They are usually the shape of the crescent moon with two edges pointing the same direction. When asphalt is continuously exposed to oil, dust, and dirt, it creates separation between the top and under the asphalt layer. When that happens, you will notice a crescent-like shape.
These are the common types of cracks that you should pay attention to. You can contact a crack sealing professional, and they will explain everything and seal the cracks.
