American Concrete Pavement Association Announces Research Results

The American Concrete Pavement Association (ACPA) announced the release of three reports documenting research results from the Airport Concrete Pavement Technology Program (ACPTP). ACPTP projects employ applied research to address challenges affecting the concrete pavement industry and provide supporting information for Federal Aviation Administration (FAA) Advisory Circular updates that help airport designers and contractors build safer, longer lasting and more cost-effective airfield pavements....


WSU Nuclear Science Center Begins 'Hot Cell' Expansion

Construction will soon begin on a major expansion of one of Washington State University's priority initiatives — the scientific and educational opportunities arising from the state's only nuclear research reactor....


Designing Cleaner, Greener Concrete That Absorbs Carbon Dioxide

From the mud, straw and gypsum mixtures of ancient Egypt's monumental pyramids to the sophisticated underwater material employed by Roman engineers in iconic structures like the Pantheon, concrete has long symbolized civilization's resilience and ingenuity....


Fugro Supports Bridge Redesign With Geotechnical Expertise

Fugro is performing a nearshore geotechnical study to support the site investigation phase for the new U.S. 51 Cairo Bridge in Ballard County, Ky. The current bridge, built in 1936, connects Wickliffe, Ky., to Cairo, Ill., and carries a high volume of commercial truck traffic over the Ohio River....


MDOT Researches Carbon Fiber Bridge Components

The Michigan Department of Transportation (MDOT) and university researchers have subjected a high-tech material to trial by fire and ice in a quest for better bridge components. Steel has historically been the go-to material for reinforcing and pre-tensioning concrete for highway bridges....


Birmingham Interstate Project Inspires University Civil Engineering Study

When the I-20/I-59 corridor through Birmingham, Ala., was demolished and rebuilt over a period of 12 months in 2019, travel became a nightmare for thousands of truckers, daily commuters and other travelers....


Deteriorated Roads Cost Birmingham Drivers Over $1,800 Per Year

Roads and bridges that are deteriorated, congested or lack some desirable safety features cost the average Birmingham area driver $1,846 per year — a total of $5.3 billion statewide — due to higher vehicle operating costs, traffic crashes and congestion-related delays, according to a recent report from TRIP, a Washington, D.C.-based national nonprofit transportation research organization....


Tunnel Studies Offer New Vision for Real-World Emissions from Heavy-Duty Diesel Vehicles

Two recent studies conducted on opposite coasts of the United States led to the same conclusion: real-world vehicle emissions have dropped considerably over time, and advancements in diesel engines and emissions controls are delivering measurable reductions in black carbon emissions (PM 2.5), nitrogen oxides (NOx) and greenhouse gases (GHG)....


Bacteria — the Solution to Salt Damage on Concrete Roads?

During a recent polar vortex event so extreme that train tracks were set alight to avoid transit slowdowns in Chicago, few people were likely concerned about the effects of salt on concrete roads. Luckily, however, Dr....


Top Sources of Uncertainty in Building Design, Construction

Recently the American Institute of Architects (AIA) and Dodge Data & Analytics and other allied construction industry parties conducted research to identify the top sources of uncertainty in design and construction along with best practices for managing associated risk....
