Laboratory and Full-Scale Testing of JETCON JC400 Rapid-Setting Concrete Repair Materials for Crater Repairs

Abstract: The DoD currently utilizes rapid-setting concrete (RSC) for a variety of applications, including capping airfield pavement repairs, to limit closure time. Laboratory and field criteria were previously developed for certifying proprietary products for use in various sizes of repairs to ensure performance under aircraft loads. A few certified products have been added to the qualified products list for larger repairs, but none are manufactured in the region near the Korean peninsula. To address this issue, a candidate Korean product (JETCON JC400) was evaluated via the established laboratory and full-scale testing protocol. One large (i.e., 15 ft × 15 ft) repair and two small (i.e., 8.5 ft × 8.5 ft) repairs were conducted and trafficked with simulated F-15E aircraft traffic. JETCON JC400 met all criteria; therefore, the authors recommended adding it to the US Air Force Qualified Products list for large and small pavement repairs. The material is compatible with all volumetric concrete mixers currently in the DoD inventory and has many other potential applications.

Rapid Airfield Damage Recovery Next Generation Backfill Technologies Comparison Experiment : Technology Comparison Experiment

Abstract: The Rapid Airfield Damage Recovery (RADR) Next Generation Backfill Technology Comparison Experiment was conducted in July 2017 at the East Campus of the U.S. Army Engineer Research and Development Center (ERDC), located in Vicksburg, MS. The experiment evaluated three different crater backfill technologies to compare their performance and develop a technology trade-off analysis. The RADR next generation backfill technologies were compared to the current RADR standard backfill method of flowable fill. Results from this experiment provided useful information on technology rankings and trade-offs. This effort resulted in successful crater backfill solutions that were recommended for further end user evaluation.
