Potholes are popping up across Iowa as temperatures fluctuate.
The Iowa Department of Transportation says potholes are mostly caused by moisture getting into or underneath pavement. During freeze and thaw periods, moisture causes the asphalt or concrete roadways to shift, buckle, or break.
When vehicles drive over these weakened areas, the patches can come loose, leaving those dreaded potholes.
Iowa DOT, as well as city and county crews, are patching potholes as quickly as they can using cold-mix asphalt. In many cases, it’s not a long-lasting solution, but it does improve your driving experience, especially on larger potholes on busy roads, until the weather warms up enough to place a more permanent patch in the spring.
