Paving the way

 Left unfilled, cracks will allow rain and moisture to flow through pavement and erode base materials ultimately resulting in potholes and pavement failure. Filling cracks with crack filler helps prevent rain and moisture from flowing through the pavement and causing erosion or failure. By stopping the entrance of water, the rate of deterioration of the pavement is significantly slowed. Crack sealing also prevents the loss of aggregate from the edges of the crack. 

 Asphalt pavement is mostly rock and/or stone and gravel, along with a binder. The rock, or aggregate, is held together with this binder known as asphalt cement. Maintaining this binder is essential to preserve the service life of asphalt surfaces. Rain, U.V. rays, and chemicals, as they are introduced into the asphalt, will degrade the binder and thus begin the degradation process of the asphalt. This will continue and create a surface that turns brittle. So, the purpose of asphalt sealcoating is to protect the asphalt pavement and to beautify at the same time. The earlier an asphalt sealer can be applied in the life cycle of asphalt the better.
