Civil engineers find savings where the rubber meets the road
Study shows that pavement deflection under vehicle tires makes for a continuous uphill drive that increases fuel consumption. CAMBRIDGE, Mass. -- A new study by civil engineers at MIT shows that using stiffer pavements on the nation’s roads could reduce vehicle fuel consumption by as much as 3 percent — a savings that could add up to 273 million barrels of crude oil per year, or $15.6...
