Improvised explosive device crater repair for enduring route remediation

<p>"Recent road repairs performed on main supply routes (MSRs) and alternative supply routes (ASRs) in Iraq and Afghanistan revealed several deficiencies in current repair techniques. Temporary solutions such as aggregate backfill, asphalt, and traditional concrete repairs were unacceptable due to the ease of emplacement of additional improvised explosive devices (IEDs). In addition to the threat of IED placement, the threat from exposure of the repair teams to enemy attack during placement and curing was substantial. In order to address these problems, this project investigated rapid hardening materials for improvised explosive device crater repair. A laboratory test program along with performance criteria was developed to evaluate mechanical, compatibility, and durability properties to ensure a viable repair. The test program evaluated the repair materials for a wide range of temperatures to make certain the repair material was suitable in all temperatures. Using the results from the laboratory investigation, a repair material was selected for the IED crater repair. In addition, the selected product was optimized using particle packing theory. The laboratory testing program was performed on the optimized mix to determine the effectiveness of the optimization. Through laboratory tests, a pre-blended rapid hardening material was recommended for crater repairs that reopen routes to traffic within 30 minutes to 1 hour after repair"--Abstract, page iii.</p>
