Seasonal preventative maintenance can protect your property asphalt from temperature changes, severe water damage and potholes, but when snow plows and road salt are added to the mix, it’s important to assess for damage after the thaw.
The most common contributor to asphalt failure in the Minneapolis-St. Paul market is frost heave. Frost Heave is the formation of ice pockets under the asphalt that is caused by the fluctuation in freezing and thawing temperatures. Ice pockets form in the soil under the asphalt and pushes the surface up as they harden. Silt or clay soils are more susceptible to frost heave than better draining soil mixtures, such as sand.
If you didn’t seal older asphalt cracks before the cold set in, make sure they didn’t expand during the wet winter months. Cracks allow water to seep into the sub-base; when that water expands and contracts with the freeze and thaw cycle, these small cracks can quickly become potholes.
As the snow thaws and temperatures rise, potholes that have gone undetected may emerge. These damages can be caused or aggravated by crack expansion or snow plow damage. You’ll want to take a pro-active approach to protecting drivers and pedestrians by patching and sealing these holes in your parking lots, driveways and sidewalks as soon as possible.
We can’t overstate the importance of even/level paving to prevent injury or accidents and avoid costly liabilities. Be sure to patch asphalt and grind down concrete to immediately reduce the liability risk that comes with tripping on uneven surfaces. A proactive approach to reducing trip/falls far outweighs a potential lawsuit and cost associated with an accident. Once you examine the damage, you can then put together a plan for full removal and replacement as needed.
At the end of the winter months, which is typically early to late April, it’s imperative to review all aspects of your asphalt surface as early as you are able to schedule services that weren’t available during the winter season, like seal-coating and asphalt patching. This measure of preventative treatment can extend the life of your asphalt areas and save on large maintenance plans over an extended period-of-time.
