  • PUBLICATION NOTIFICATION: Evaluation of Rapid-Setting Cementitious Materials and Testing Protocol for Airfield Spall Repair

    Abstract: The rapid-setting cementitious material certification program is part of a research effort to assist the U.S. Air Force Civil Engineering Center in the execution of independent testing on select commercially available proprietary products to repair partial-depth spalls in airfield concrete pavements. The purpose of this research was to determine whether the existing requirements for evaluating rapid-repair products for spall repairs were sufficient or further refinement and modifications were needed. This protocol is intended to aid airfield managers and repair teams in the selection of optimal spall repair materials by maintaining a database of approved tested products. This report presents the test methods and results of 26 cementitious rapid-setting repair products tested at the U.S. Army Engineer Research and Development Center in Vicksburg, MS, during 2013 to 2017. An evaluation of these test methods and results, along with the historic database of products tested, led to the development of an updated testing protocol for assessing a material’s suitability for airfield spall repairs. Based on the revised criteria, 10 products were identified as most compatible for partial-depth airfield pavement concrete spall repairs.
