EXTEND THE LIFE OF YOUR ASPHALT
When done properly, crack filling can extend the life of your driveway or parking lot. By sealing cracks in your asphalt you avoid water-based erosion. This also prevents sand and rocks from making their way to the surface, widening the cracks. Asphalt crack filling will minimize crack growth and keep new cracks from forming. Treating the problem areas in your asphalt while they are small is key to proper maintenance- delaying the need for costly asphalt resurfacing.
EFFECTS OF FREEZE-THAW
HOW CRACKS FORM IN YOUR ASPHALT
Surface oxidation from sunlight weakens the asphalt binder that holds the blacktop together.
Surface becomes brittle, hairline cracks appear, aggregate raveling creates rougher surface.
Cracks reach sud-surface, water penetration and freeze/thaw cause surface separation.
