With the shift from winter snow plowing to snow melting, conditions are perfect for potholes to form in the spring.
Moisture seeps into the pavement and sub-base, freezes, expands, and then thaws.
The ‘freeze, thaw' cycle weakens the pavement.
Traffic loosens the pavement even more.
Pavement crumbles and pops out.
Potholes can develop on a daily basis when temperatures begin to hover around zero degrees.
