Abstract:

This report documents the repair process of five craters in cold weather utilizing rapid-setting flowable fill RSFF and rapid-setting concrete RSC. The work discussed herein supports the Rapid Airfield Damage Recovery RADR Program, in which the main objective is to develop capabilities to rapidly repair damaged airfield pavements for the full spectrum of operational scenarios. The purpose of this report is to document constructability, to collect early-age properties pertinent to the ability of these crater repair techniques to carry aircraft traffic, and to measure performance by exposing crater repairs to simulated aircraft traffic. Crater repair testing 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 cold weather, but repairs utilizing it did not perform well. The most efficient manner of using RSFF in cold weather was to heat the mix water. With heated mix water, a rapidly placed pavement repair was able to withstand 100 passes of an aircraft load cart after approximately 2 hr of cure time where RSFF was the backfill and RSC was the cap.
