Amid budget shortfalls, state money for local roads has been cut and so paved roads across the nation are being torn up and replaced with gravel.
"Rebuilding an asphalt road today is particularly expensive because the price of asphalt cement, a petroleum-based material mixed with rocks to make asphalt, has more than doubled over the past 10 years. Gravel becomes a cheaper option once an asphalt road has been neglected for so long that major rehabilitation is necessary."
"The moves have angered some residents because of the choking dust and windshield-cracking stones that gravel roads can kick up." But as long as higher taxes to pay for paved road maintenance remain unpopular, many municipalities have little choice.
"A lot of these roads have just deteriorated to the point that they have no other choice than to turn them back to gravel," says Larry Galehouse, director of the National Center for Pavement Preservation at Michigan State University. Still, "we're leaving an awful legacy for future generations."
