CHADRON, Neb. (AP) —
The federal government has agreed to pay up to $7.5 million to help
repair taxiways and the main runway at Chadron Municipal Airport in
The work is needed because
concrete from a repaving project in 2000 has failed.
Public Works Director Milo Rust says the horizontal cracks were
discovered last summer during a sealing project. He says the concrete
failure has been blamed on an unexpected chemical reaction involving the
silica sand used in the cement mix.
Rust says experts aren't sure
what caused the reaction. He says the concrete used in 2000 met
specifications and passed required tests at the time.
He expects the project will begin next spring and could take a year.
