Spring brings a welcome respite for many in Maine who braved a bitter winter and are now looking forward to warmer days ahead. But for drivers, spring also brings what can be an unexpected hazard: frost heaves.
These are an uplift of water-soaked soil or other surface deposits that rise up due to expansion and freezing. In some cases, the rise can be so dramatic that it breaks through the pavement of the road, creating a major risk for drivers. Maine residents have given the road features many monikers: asphalt crevasses, nature’s speed bumps, chuck holes, and paved divots. Although they regularly appear every spring season, they can still catch operators by surprise.
