MoDOT is urging motorists to watch out for summer blow-ups on area roads. Though not as dramatic as the name would imply, pavement “blow-ups” are the summer’s version of potholes and can lead to a surprise bump or two in the road.
Despite the term, the pavement doesn’t actually explode. Pavement blow-ups are fractures that occur when the road surface expands at a crack or joint where moisture has seeped in. That crack weakens the pavement, and the high summer temperature causes the pavement to buckle, creating holes in the surface.
You can report pavement blow-ups at 1-888-ASK-MODOT. But remember, never make a cellphone call from behind the wheel.
Buckle up phone down.
