Stiffer Pavements Could Reduce Fuel Consumption and CO2 ...

May 23, 2012  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 billion at today’s oil prices. This would result in an accompanying annual decrease in CO2 ...
