A research study was conducted at the U.S. Army Engineer Research and Development Center ERDC in Vicksburg, MS, to evaluate methods for preventing rainfall runoff from entering open bomb craters during wet weather repairs. The study evaluated the use of seven commercial off-the-shelf barriers on both smooth and grooved concrete pavements. Water runoff, particularly in grooved concrete pavements, is one of the greatest challenges for repairing craters in wet weather. Also included in the evaluation was a heavy duty pop-up tent placed over the open repair area. This report presents the technical evaluation of the various water barriers and the pop-up tent using simulated rainfall of approximately 1 in.hr. Results indicate that, along with a pop-up tent, a 6-in.-wide berm of compacted sand is the most effective barrier for grooved and smooth pavements. A polyvinyl tarp is also effective for smooth pavements. A sand berm, polyvinyl tarp, and a pop-up tent are recommended for use as supplemental items by crater repair teams during times of wet weather.
