HANOVER, N.H.—Two ERDC laboratories, the Geotechnical and Structures Laboratory’s (GSL) Airfields and Pavement Branch and the Cold Regions Research and Engineering Laboratory’s (CRREL) Force Projection Branch, recently teamed up to perform a cold weather test on new airfield damage repair (ADR) materials in CRREL's Frost Effects Research Facility (FERF), May 28-June 7, in Hanover, N.H.
The ADR team completed five tests to evaluate the effects of cold weather on the production and placement of rapid-setting flowable-fill backfill in simulated bomb craters.
The pavement inside the FERF was frozen to a depth greater than 36 inches and the inside air temperature during testing was sustained below 32 degrees Fahrenheit.
Additionally, the team evaluated the performance of ADR equipment and CTS Rapid Set concrete under sustained cold temperatures.
The test results are being used to modify the tactics, techniques and procedures for performing bomb crater repair for airfields in cold environments.
