‘Talking’ concrete could help prevent traffic jams and cut carbon emissions

An increasing number of U.S. interstates are set to try out a Purdue University invention that could save millions of taxpayer dollars and significantly reduce traffic delays.

The invention, a sensor that allows concrete to “talk,” decreases construction time and how often concrete pavement needs repairs while also improving the road’s sustainability and cutting its carbon footprint.

Embedded directly into a concrete pour, the sensor sends engineers more precise and consistent data about the concrete’s strength and need for repair than is possible with currently used tools and methods…

More than half of U.S. states with concrete interstate pavement have signed up to participate in a Federal Highway Administration pooled fund study to implement the sensors. The participating states are Indiana, Missouri, North Dakota, Kansas, California, Texas, Tennessee, Colorado and Utah.

The technology also is on track to hit the market later this year as the REBEL Concrete Strength Sensing System, a product of WaveLogix.
