EFFECTS OF FREEZE-THAW
HOW CRACKS FORM IN YOUR ASPHALT
1.
Surface oxidation from sunlight weakens the asphalt binder that holds the blacktop together.
2.
Surface becomes brittle, hairline cracks appear, aggregate raveling creates rougher surface.
3.
Cracks reach sud-surface, water penetration and freeze/thaw cause surface separation.
