Rapid Setting Flowable Fill Performance in Cold Weather for Airfield Damage Repair
This report documents the repair process of five craters in cold weather utilizing rapid-setting flowable fill (RSFF) and rapid-settingconcrete (RSC). The work discussed herein supports the Rapid Airfield Damage Recovery (RADR) Program, in which the mainobjective is to develop capabilities to rapidly repair damaged airfield pavements for the full spectrum of operational scenarios. Thepurpose of this report is to document constructability, to collect early-age properties pertinent to the ability of these crater repairtechniques to carry aircraft traffic, and to measure performance by exposing crater repairs to simulated aircraft traffic. Crater repairtesting occurred at the Frost Effects Research Facility at the ERDC Cold Regions Research and Engineering Laboratory in Hanover,NH. Results showed RSFF could be a suitable cold-weather backfill. Aluminum sulfate was tested as an additive for use in coldweather, but repairs utilizing it did not perform well. The most efficient manner of using RSFF in cold weather was to heat the mixwater. With heated mix water, a rapidly placed pavement repair was able to withstand 100 passes of an aircraft load cart afterapproximately 2 hr of cure time where RSFF was the backfill and RSC was the cap.
