Good day everyone,

I am pleased to notify you of an important new Texas Fuel Consumption and
Emissions Study for Concrete Paving Study that has been just released by The
RMC Research & Education Foundation.

See the news release below and/or click this link to see the study including
its Executive Summary
http://www.aggregateresearch.com/resources/items/RMC%20Foundation/UTA%20FCS%20Final%20Report%203-10.pdf

Notable Summary Excerpt:

For example, if the annual vehicle miles of travel in the Dallas-Fort Worth
(DFW) region in Texas took place hypothetically at a constant speed of 30
mph all on PCC

pavements similar to the test sections in this study, the statistically
lower fuel rates could result in an annual fuel savings of 177 million
gallons and an annual CO2 reduction of about 0.62 million metric tons.
Assuming an average fuel cost of about $2/gallon and an average CO2 clean-up
cost of about $18/metric ton, these differences would amount to a savings of
about $365 million per year in the DFW region.

A quick unofficial extrapolation of those numbers for the nation, based on
the population of the study area of the DFW Metroplex, pencils out as such:

Assumption: DFW Metroplex has a population of c.6.3 million (2% of the US
{c.305m}). For the nation, and hypothetically, of course, that extrapolates
to potential nationwide savings of:

• $18,250,000,000 per year or $18.2 B/yr
• 8,850,000,000 gallons per year or 8.8 B gal/yr
• Reduction of 31,000,000 metric tons of CO2 per year or 31 million

metric tons of CO2/yr

By simply using rigid PCC pavements vs flexible pavements in our
infrastructure.

Important Note: This data is currently being peer reviewed at MIT.

Best regards,
Rob
