The short answer

Crack sealing should be considered before winter because water entering open cracks can freeze, expand, and accelerate pavement damage.

Why freeze-thaw cycles matter

Ohio pavement expands and contracts through seasonal temperature changes. When water is trapped in cracks, winter weather can make small pavement issues much worse.

When to act

Property owners should schedule crack sealing when cracks are visible, before they become wide failures or allow water to reach the pavement base.

How it fits a maintenance plan

Crack sealing is often paired with sealcoating, asphalt patching, and line striping as part of a practical pavement maintenance schedule.
