Abstract

Recent road repairs performed in Iraq and Afghanistan revealed several deficiencies in current repair techniques. Temporary solutions such as aggregate backfill were unacceptable due to the ease of emplacement of additional explosive devices. Additionally, asphalt repairs were easily penetrated with common hand tools to place improvised explosive devices (IEDs) where tampering was difficult to recognize. Concrete patches proved to be short-term solutions, as hasty concrete repairs deteriorated under traffic, providing access for additional IED placement. While traditional concrete placement exposed repair units to enemy attack due to extended material production and cure times. As a result this investigation is being conducted in conjunction with the U.S. Army Engineer Research and Development Center (ERDC) to determine the most promising rapid-setting material alternatives for capping IED crater repairs. This research makes use of the standard test methods and the required vehicle load rating to provide recommendations for selection of rapid-hardening materials and equipment for conducting repairs that will reopen routes to traffic within 30 minutes to 1 hour of repair.
