Video: Science to Reveal How Long Highway Construction Should Actually Take
The Indiana Department of Transportation (INDOT) tasked a team of Purdue University engineers with collecting data on concrete maturity through select highway patching and paving projects. The team will use the data to provide a new evidence-based recommendation on the optimal time to open up traffic following a construction project, which would save time and reduce traffic slowdowns.
Purdue engineering researchers are collecting data through piezoelectric sensors designed to track concrete strength development in real time through measurements of hydration, stiffness, compressive strength and other properties of concrete. After testing, INDOT plans to adopt the sensors, allowing them to permanently live in highways and continuously keep contractors informed on concrete distress.
