Smooth roads conserve energy and extend the life of pavements.

Studies at a pavement test track in Nevada have shown that driving on smoother surfaces can reduce fuel consumption in the neighborhood of 4.5 to 5 percent compared to fuel consumption on a rough pavement. A study in Sweden concluded that vehicles traveling on the smoothest roads in that country’s network consumed up to 10 percent less fuel than vehicles on their roughest roads.

Smoother pavements also result in longer pavement life by as much as 10 to 25 percent, resulting in lower maintenance costs. As a rule, asphalt pavements are smoother than concrete pavements. Smoothness measurements on interstate highways in Oregon and Washington showed that asphalt pavements are on average 33 percent smoother in Oregon, and over 50 percent smoother in Washington.

Smoothness also means that truck tires don't bounce on the pavement and deliver the kind of impact loading they would on a rougher pavement. Some experts estimate that increasing pavement smoothness by 25 percent results in a 9 percent to 10 percent increase in the life of pavements.

Smooth pavements save money for motorists, too. According to The Road Information Program, driving on roads in poor conditions costs around $400 per year per vehicle annually.
