VIDEO: Foam injections help NCDOT reopen I-95 after flooding from Hurricane Florence

Equipment World » Hurricane Florence turned large sections of Interstates 95 and 40 into rivers, cutting off major north-south and east-west connections in the eastern part of the state. A week later, after flood waters receded, work crews drilled holes in pavement near two flooded bridges at the Lumber and Black rivers. The foam was injected into the holes. It hardens and stabilizes the ground beneath the road making a permanent repair to any holes that have formed underneath, NCDOT says.

Researchers develop first fungus-oriented self-healing concrete

Press & Sun Bulletin » Within three years, Binghamton University and Rutgers University researchers hope to perfect a fungus — rather than a bacteria — that will organically heal cracks that develop in concrete. Moisture that seeps in would germinate the fungus, which would create mineral deposits that could fill cracks even larger than those used in the bacteria experiments.

California bridge could transform industry with nanocrystals

Construction Connect » A new bridge will be built in California this summer. That’s hardly earth-shattering news. But this one will be different. Thanks to the work of researchers at Purdue University, this bridge will use concrete that has been infused with microscopic-sized nanocrystals from wood. The idea is that the nanocrystals will make the concrete stronger so that less of it is needed.
