| 摘要： | An increasing number of U.S. interstates are set to try out a new sensor from Purdue University in West Lafayette, Ind., that could save millions of taxpayer dollars and significantly reduce traffic delays. The sensor allows concrete to "talk," decreasing construction time and how often concrete pavement needs repairs, improving the road's sustainability, and cutting its carbon footprint. Embedded directly into the concrete when it is placed, the sensor sends engineers more precise and consistent data about the concrete's strength and need for repair than is possible using current methods. "Traffic jams caused by infrastructure repairs have wasted 4 billion hours and 3 billion gallons of gas on a yearly basis. This is primarily due to insufficient knowledge and understanding of concrete's strength levels," says Luna Lu, the Reilly Professor and acting head of Purdue's Lyles School of Civil Engineering. "For instance, we don't know when concrete will reach the right strength needed to accommodate traffic loads just after construction. The concrete may go through premature failure, leading to frequent repairing." |
