Asphalt is commonly used in construction projects for its resilience and durability for paved surfaces. And when the pavement is well-built and protected with asphalt sealing, it can last for up to 25 years. Conversely, poorly constructed asphalt paving often develops cracks that can cause the entire structure to deteriorate rapidly.
5 Kinds of Cracks That Can Appear on Your Asphalt Pavement
1. Block Cracks
As the name suggests, these are the square-shaped or rectangular cracks you sometimes see on the road. Block cracks usually happen when the aggregate was too dry when it was applied. Freezing temperatures can also cause cracks due to the shrinkage in the asphalt. A thin asphalt sealing overlay can fix the issue.
2. Alligator Cracking
This is one of the most common types of asphalt cracking, earning its nickname because it resembles alligator skin. It’s caused by harsh weather conditions, a subpar drainage system, or insufficient foundation materials. To fix it, contractors need to carry out a full patch-up of the pavement.
3. Edge Cracking
You can see these cracks at the edge of a parking lot or road. They're caused by weak asphalt, poor drainage, or strong frost heaves. Reduce incidents of cracking by clearing all debris or overgrowth found at the edge of the pavement and improving drainage. Doing this should be followed by filling the cracks with asphalt sealing.
4. Longitudinal Cracks
These indicate a weakened joint structure of traffic lanes that are beside each other. Dry and cold weather often worsen the situation and cause these cracks to form. Asphalt sealing can quickly repair them.
5. Transverse Cracks
You can see these vertical cracks in high-traffic parking lots or on main roads. They're caused by the combination of an overused pavement and cold temperatures. Joint sealing material can be poured into the cracks to patch them up.
