In West Lafayette, a Purdue professor says roadways need a “digital transformation”. Luna Lu at the Lyles School of Civil Engineering and director of the Center for Intelligent Infrastructure at Purdue is an expert in innovating concrete to improve roads. She says fewer repairs would mean fewer construction delays, also noting that ‘smarter’ roads could be better for the environment. Lu and her collaborators are working on materials that would reduce the amount of carbon dioxide generated in the production of cement. Lu’s lab is also developing a way concrete could heal its own cracks. Here’s a link to read more.
