Different Type of Pavement Cracks and How to Repair
Winter’s here, so there’s no more putting off those cracks that are ruining your commercial property. As a property owner, the cracks may not look like much, but the potential for these cracks to seriously damage your asphalt pavement is considerable.
When thinking of the different types of cracks and how they impact you asphalt paving, it’s important not to wait too long before getting repairs done. Cracks get worse the longer you leave them unattended and quickly go from a small fix to something much more complicated.
Fatigue (Alligator) Cracking
The constant heavy traffic on your commercial property is the cause of what is called alligator cracking. The term is given because the cracks literally look like the skin of an alligator. If alligator cracks aren’t tended to immediately, they can cause water seepage and potentially even structural failures. Full-depth patching is the answer for this type of cracking.
Block cracks are rectangular cracks in your asphalt that can lead to water seepage and leave the surface rough. A thin overlay should do the trick for any block cracking.
Poor drainage, heavy traffic, and frost heave are just some of the root causes of edge cracks. The best way to address this issue is to remove the vegetation around the edge of the cracks and improve the drainage.
A paving joint crack that has not been constructed up to standards will transform into linear cracks. These cracks run parallel to the centerline of the pavement or direction of the laydown. Cracks less than a half inch can simply be sealed with crack filling while anything more severe requires removing the cracked pavement and putting overlay in its place.
Cracks that run perpendicular to the centerline laydown are called transverse cracking. The changing weather is typically a cause of transverse cracking. Similar to linear marks, smaller cracks can be sealed while larger cracks require overlay.
Reflection cracking occurs right above pavement joints. Sealing for these types of cracks will help keep the moisture out, but a complete overlay may be necessary should too much damage already be done.
Slippage cracks look a lot like a crescent. It’s a huge problem because it digs into the surface layer of asphalt and stays that way till something is done. A partial or full-depth patch will be required on all areas where these slippage cracks are present.
Everyone hates potholes. They are disruptive and damaging because they dig down through to the base course of the asphalt or pavement. Usually moisture is the initial perpetrator of potholes, and the only way to repair potholes is by full-depth replacement patch.
When you see sinks or depressions in the wheel tracks, you’re likely looking at rutting. Crack filling and an overlay should be able to repair the rutting. But if the rutting is too severe, then it should be completely replaced with a different material.
When a pavement is lined with the formation of what are called ripples, which are the formation of shoving. Too much horizontal stretching of the asphalt is usually the culprit of shoving. A partial or full-depth patch is the only ways to go.
