Effect of Pavement Type on Fuel Consumption and Emissions in City Driving demonstrates that vehicles exhibit consistently--in some cases, markedly--lower fuel consumption and emissions rates on concrete versus asphalt pavements. This new study demonstrates yet another way how the use of concrete can have a positive impact on the environment. We have significant data that will provide state DOTs additional information necessary to make informed choices about pavement selection, especially regarding life cycle, environmental and air quality considerations, says RMC Foundation Chairman Jim Repman (CalPortland).
The report tracks research from University of Texas at Arlington's Dr. Siamak Ardekani and Palinee Sumitsawan comparing fuel consumption and total carbon dioxide emissions for a motor vehicle driving on Dallas-Ft. Worth-area asphalt and concrete pavements. It also includes a new spreadsheet program tool, Roadway Fuel Consumption and Emissions Calculator, for estimating savings or costs based on user-specified project conditions. The specifying community should find these results and the accompanying calculator extremely useful when selecting pavements. WeÌre delighted to add [them] to our Research to Support Sustainable Development CD, notes Foundation Executive Director Julie Garbini.
