At 11:30 one February morning, drivers on Highway 22 just east of Centralia in Audrain County in Missouri reported a large hole in the westbound lane of the reinforced concrete deck of the 67-year-old Youngs Creek Bridge. Missouri Department of Transportation’s (MoDOT) Northeast District bridge crews immediately closed the lane to make an emergency repair using CTS Cement Manufacturing’s Rapid Set® DOT Cement.

A specially formulated blend of Rapid Set® Cement and high-performance additives, Rapid Set® DOT Cement is used throughout the state for bridge repairs because it is ready for traffic and loading in 1 hour, allows for customized mix designs according to the application, and is air-entrained for long life in freeze-thaw environments.

MoDOT's St. Louis District bridge crew was called to provide a volumetric mixer truck, which could quickly mix the large volume of material required to fill the hole.

CTS’ manufacturing plant and distribution facility in Mexico, MO, arranged for an after-hour pickup of the cement and MoDOT crews began working around 4:00 p.m. Thanks to their experience and the ASTM C1600 very-rapid-hardening cement, the bridge was reopened to traffic at 11:30 p.m.
