What Causes Asphalt to Crack

Once the cause of the cracking is determined, we can devise a custom plan for repairing the asphalt. Before the repair process can begin, the asphalts surface must be correctly prepared. If sand, dirt and other debris are not removed from the cracks, the crack filling material cannot adhere properly. Pressurized air is often used to help remove moisture and vegetation from cracks and a steel brush is also used to help remove debris from the cracks. Asphalt crack repair can also begin with routing. This method uses motorized equipment, called a router, to create a reservoir that has a smooth surface. The routing makes the cracks a more consistent size and allows the crack filling material to contract and expand more evenly.

About cracks…

  • Weather:
he weather plays a huge part in the development of cracks. Sun dries the oils in the asphalt making it more brittle and susceptible for damage. Rain water flows to the path of least resistance and sometimes it can get into micro cracks, or other damage on the asphalt surface and seep into the base layer. If it freezes this is something else that can lead to damage with the expansion and contraction of ice. Neglecting these cracks allows water to penetrate the pavement, softening the asphalt and resulting in eventual failure of the surfaces.
  • Vehicle traffic:
vehicle weight and traffic can also accelerate deterioration causing cracks to develop and sometimes causing aligatoring or break-up, even into potholes. Whether it is crack filling, patching, potholes, sealcoat or striping we can help!
  • Weak base layer:
Once the base layer is damaged there is no going back to the original state, it will be a matter of limiting damage and buying time from here out. If asphalt has gotten to the pothole or break-up stage the damage will need to be cut out, base layer repaired and re-patched. Don’t let your asphalt get to this stage!

How do you control?

Simply put….

Before the repair process can begin, the asphalts surface must be correctly prepared. If sand, dirt and other debris are not removed from the cracks, the crack filling material cannot adhere properly. A wire brush is used to help remove debris from the cracks. Material is heated to between 350* and 425* and poured into the cracks. This helps prevent water from getting in anymore.
