The moisture and subfreezing temperatures characteristic of Alaska's Kenai Peninsula are a perilous combination where asphalt is concerned. Blacktop damage becomes rampant in winter, so if your driveway or parking lot is cracked and in need of repairs, you might be considering asphalt crack filling or sealing. Veir Corp., the premier driveway repair company in Sterling, AK, can help you understand the differences between the two. With nearly three decades in the paving business, they have the experience and expertise to repair and protect your lot or driveway, even under some of the harshest conditions on Earth.

Asphalt Crack Filling

The most common cause of asphalt damage is moisture that seeps into or below the surface. When the moisture freezes, the ice expands and leaves cracks and potholes in the surface. Asphalt crack filling is typically chosen for nonmoving cracks with little edge deterioration, where the horizontal and vertical movement of the asphalt is expected to be 0.1 inches or less. Nonrubberized crack filler is used, since little need for flexibility is anticipated. Before patching, a hammer and chisel should be used to remove loose or broken pieces, and the area should then be cleaned with a wire brush and air gun to remove particles and debris. Cracks are filled using a caulking gun and putty knife. Larger cracks may first be filled with gravel before the filler is applied. Finally, the filler is tamped down until the surface is level.

Asphalt Crack Sealing

Crack sealant is applied in a similar fashion but is a different substance from what is used in asphalt crack filling. It is a rubberized adhesive material used to seal cracks that are likely to increase in size. It can flex without splitting as the cracks widen. Asphalt crack sealing restricts water penetration and prevents further deterioration. Often, it takes an experienced professional to determine whether a crack is a moving or nonmoving type.
