Some Roads Interstates across America are poised to test an innovation that could save taxpayers millions of dollars and significantly reduce traffic delays: A concrete Who’s talking!

A sensor that allows the invention Concrete The ‘fale’, in addition to improving the road’s sustainability and reducing its carbon footprint, reduces construction time and the frequency of concrete pavement repairs.

How does it work?

Directly connected Concreteoh sensor Sends accurate and consistent data on material strength and repair requirements to engineers. This method is more modern than the tools currently used.

“Traffic congestion caused by infrastructure repairs wastes 4 billion hours and 3 billion gallons of gasoline annually, largely due to inadequate knowledge and understanding of concrete strength levels,” said Luna Lu, Reilly’s professor and acting dean of Purdue’s Lyles School. Civil Engineering.

Purdue University in the United States has been at the forefront of developing sensors since 2017.

“For example, we don’t know when it will reach the required strength to accommodate traffic loads soon after construction. Concrete can fail prematurely, leading to frequent repairs,” the professor told Science Daily.

Concrete on North American Highways

According to Federal Highway Administration data, concrete pavement makes up less than 2% of U.S. roads, but approximately 20% of the U.S. interstate system.

Lu’s research first focused on improving concrete pavement conditions Road material Difficult to repair.
