The change of seasons in the Midwest brings a unique challenge to property owners: the frost-thaw cycle. This relentless process of freezing and thawing is by far the primary enemy of asphalt and concrete pavements, leading to cracks, potholes, and costly repairs. At Walsh Sealcoating & Snow Removal, we understand this seasonal assault better than anyone. We want to help our clients understand the science behind this damage so we can collectively protect their valuable pavement assets before winter arrives.
The Frost-Thaw Cycle: Why Midwest Winters are the Primary Enemy of Pavement Integrity
The Frost-Thaw Cycle: Why Midwest Winters are the Primary Enemy of Pavement Integrity
The Science Behind Water Intrusion and Expansion
When temperatures drop below freezing, any water that has penetrated the pavement's surface—via small cracks or porous asphalt—expands as it turns to ice. This hydrostatic pressure stresses the internal structure. The constant fluctuation of temperatures causes ice to melt and then refreeze, widening existing fissures over time. We focus on prevention to mitigate this.
Why Sealing is the Crucial Defense Layer
Sealcoating creates a vital, non-porous barrier on the pavement surface. This protective layer effectively blocks water from entering the sub-base and penetrating the asphalt itself. By stopping water infiltration, we directly interrupt the frost-thaw cycle's destructive process. This simple step is the most cost-effective way to preserve your parking lot's integrity.
Destructive Effects on the Pavement's Sub-Base
Water that seeps through cracks eventually saturates the soil and aggregate layer beneath the asphalt, known as the sub-base. When this sub-base freezes and expands, it causes the pavement above to lift and shift. As the ground thaws, the supporting structure weakens, leading to pavement failure, alligator cracking, and severe potholes in the Lombard area.
Strategic Repairs Reduce Future Winter Damage
Addressing small cracks and failures before winter is essential. We utilize professional crack-filling techniques that seal openings with flexible, durable material, preventing water from reaching the sub-base. By performing these strategic, high-quality paving repairs now, we dramatically reduce the surface area vulnerable to ice expansion and the resulting, costly damage later on.
