Asphalt Crack Repair

Sealing cracks in your asphalt pavement surface is part of proper asphalt maintenance. It is important to have repairs done as soon as the first cracks are visible. Sealing your asphalt cracks in a timely manner can greatly extend the life of your asphalt pavement and Black Diamond Sealcoating offers asphalt crack repair in Portland, OR and the surrounding areas.

What Causes Asphalt to Crack

Cracks allow water under the pavement, causing erosion in the underlying materials, which can lead to potholes requiring costly repairs. Dirt, sand and other debris make their way very easily into unsealed cracks. This debris interferes with the natural expansion and contraction of the asphalt, resulting in a variety of pavement defects.

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.
