Engineers with InTrans’ PROSPER are working with the Iowa DOT to test heated-pavement technology developed on campus. The test slabs at the Iowa DOT are smarter and more complex than the research group’s previous tests at the Des Moines International Airport. And so far, preliminary tests indicate the system works well — even in this winter’s subzero temperatures. More

New research on internal curing now online

A new research project, “Extended Life Concrete Bridge Decks Utilizing Internal Curing to Reduce Cracking,” prepared for the Ohio Department of Transportation addresses the ongoing concern about premature cracking of concrete bridge decks by looking into the benefits of using lightweight fine aggregate (LWFA) in concrete mixtures to provide internal curing.
The report includes a suggested specification for internally curing concrete with LFWA to increase the probability of achieving crack-free, long-lasting bridge decks. More
