New Asphalt Advancements Come Just in Time for Pothole Season

Roads could soon fix themselves as researchers make progress in developing self-healing asphalt. According to a team of Swiss researchers ETH Zurich and the Swiss Institute for Materials Science a new asphalt mixture made with a magnetic nano-particulate additive would prevent potholes from forming at all, and what's more, the mixture would lengthen roads' lifespans, the News Wheel reported....


Self-Healing Concrete? Researchers Say It's Possible

Researchers at Binghamton University, SUNY, have developed a new kind of self-healing concrete that could help prevent damage to infrastructure across the U.S. According to Congrui Jin, assistant professor of mechanical engineering at Binghamton, big concrete infrastructure issues usually begin with the smallest of cracks, Science Daily reported....


New Mixture Could Strengthen Concrete Up to 15 Percent

Some MIT students have found a way to create stronger, more environmentally friendly concrete. A team of undergraduate students have learned that exposing plastic flakes to small amounts of gamma radiation, grinding them into dust and then mixing the dust with cement paste and fly ash will produce concrete that is up to 15 percent stronger than a traditional mixture, MIT News reported....


In-Vehicle Warnings Show Promise for Improving Work-Zone Safety

Work zones can be dangerous for both drivers and the work crew—but University of Minnesota researchers are working on innovative ways to lessen these risks and lower the rate of work-zone crashes....


Researchers Develop New Material to Protect Buildings From Earthquake Damage

It was while flipping through British Columbia's seismic upgrade guidelines at the beginning of his civil engineering master's degree that Salman Soleimani-Dashtaki first realized something was amiss....


Steel Core Method Promises New Approach to Skyscraper Construction

A new method of building steel-framed skyscrapers is coming into play. The sandwich system consists of two steel plates that have been filled with concrete, the Engineering News-Record reported. According to engineers testing out the new method, the structure allows for the same strength, safety and serviceability as a typical reinforced concrete core would, but without the challenges rebar brings with it....


Researchers Create Snow-Melting Concrete as Salt Alternative

Just in time for snow removal season, researchers have developed a concrete mixture that melts snow on its own. A Drexel University research team has found that adding paraffin wax to concrete roads allows for the concrete to melt snow without the aid of salt, Forbes reported....


Earthquake Lab Tests New Bridge Design After Mexico Quake

Scientists at a Nevada earthquake lab on Sept. 20, tested new bridge designs with connectors they say are innovative and created to better withstand violent temblors and speed reconstruction efforts after major quake damage....


What Makes Concrete Crack? Researchers Look to Canadian Dam for Answers

Researchers from MIT's Concrete Sustainability Hub (CSHub), the University of New Brunswick and Oregon State University have teamed up to take a closer look at the durability of concrete in construction....


Global Excavator Demand to Exceed $50B in 2021

Global demand for excavators is forecast to advance 9.9 percent per year through 2021 to $50.6 billion, approximating the average market pace, according to recent data from The Freedonia Group. Growth in the segment will be supported by:advances in global building and nonbuilding construction spending....
