摘要: There are more than 8 million lanemiles of road in the U.S. Over two-thirds are paved, nearly all with asphalt. Due to decades of inadequate funding, deferred maintenance, and increased traffic volumes, much of the system has significantly degraded. Potholes are a significant result of the poor condition of our roadways. But what exactly is a pothole? Though there is no one universal definition, a commonly accepted description is that a pothole is, "a depression in asphalt (not concrete) with sharp, uneven edges, and typically ranges from 2 in. to 4 in. deep and several inches more in length than width."
