September is here in the Twin Cities, which means cold weather is just around the corner. Make sure that you and your asphalt are prepared for whatever weather may come over the next few months by investing in high-quality, professional sealcoating!
Though you likely already know that professional crack sealing is important to preserving your asphalt, you may need to know more about the process. Here are some interesting facts about the asphalt crack sealing process to keep in mind this fall.
Types of Cracks: When applying a crack sealant, the goal is to keep cracks at bay. But not all cracks are created equal; each crack forms differently, depending on the weather and type of damage. Traverse cracks run horizontally across your surface, while longitudinal cracks run parallel to, sometimes along a centerline, of the pavement. Reflective cracking is the result of failing pavement sometimes seen on asphalt overlays. Alligator or mapping cracks are the result of a failing base underneath the pavement. This type of cracking can be due to repeated stress loads or improper base compaction.
Proper Timing: Asphalt crack sealing is always helpful for preserving the surfaces of parking lots, but application is best before the cold weather sets in. Otherwise, there is an increased likelihood that moisture from rain or snow melt may settle into the asphalt, freeze, expand and form cracks. Crack sealing slows down the asphalt deterioration process which in turn can make for a safer surface.
Application Process: And what, exactly, does that application process involve? Before crack sealing a surface, you need to make sure the area is clear of dirt and debris. A professional company will rout cracks according to MNDOT specifications, remove debris and vegetation, and then apply the rubber flush with the surface. Settling of the hot material is normal as the material contracts when it cools.
