frost heaves
Ice-lifted road bumps
Frost heaves are bumps or ridges in pavement caused by cycles of freezing and thawing.
Water seeps into cracks, freezes and expands, lifting the road surface.
Common in cold climates, they create rough, uneven stretches that jostle vehicles: Watch out for frost heaves on this stretch of highway.
Road signs often warn drivers where frost heaves are likely.
