Saggy Roads Waste Fuel, Cost Money

May 28, 2012 · Print This Article

Civil engineers from MIT have completed a study in which they have determined that vehicle fuel consumption could be reduced by as much as 3 percent by having stiffer roads. Looking at the way forces interact amoung the tire and the road, the researchers conclude that, “This has the effect of making the tires on the vehicle drive continuously up a slight slope.”

Inefficiencies due to saggy roads are responsible for the use of an

additional 273 million barrels of crude oil per year (costing $15.6 billion at today’s oil prices) and producing CO2 emissions of 46.5 million metric tons. In addition to the fuel savings, building better roads would reduce maintenance costs, providing long-term savings and improved national infrastructure.

“We’re wasting fuel unnecessarily considering pavement design has been based solely on minimizing initial costs more than performance — how well the pavement holds up […]
