April showers bring May flowers, but they also bring potholes!
Dr. James Crovetti, Associate Professor in the College of Engineering at Marquette University, joined Wisconsin’s Morning News to talk about the science behind the phenomenon.
“Generally, you have a pavement surface which has cracking and that allows moisture to get into the pavement below the surface and essentially saturate what’s down there and weaken what’s down there.”
Crovetti says there are better ways to build roads that would keep this from happening, but it’s much more expensive.
The Midwest is one of the worst areas for potholes because of the constant freeze-thaw cycle.
