High temperatures cause U.S. 27 to buckle

Staff Writer

The Indiana Department of Transportation is working to repair a road buckle on U.S. 27 north of Decatur, caused by the extreme heat. This photo from the INDOT social media page shows what can happen as the sun heats the pavement, causing the pavement expand beyond its capabilities — and then buckles. Buckles more commonly occur on concrete pavements. When concrete slabs expand beyond the space in the joints they press against each other, causing the surface to buckle at the joint or in a weak spot within the slab.
