Capping Material for Compacted Runway Crater Repairs

In the Phase-I project Bhawin will advance the manufacturing technology that has already developed Capping Material for Runway Crater Repairs in-house. In Phase I project, Bhawin will develop Capping Material and related low-cost manufacturing process to achieve a nontoxic technology that supports aircraft operations within an hour of application over a spall or compacted runway repair, completely suppresses escape of debris from the repair, and survives 2,000 landing-and-takeoff cycles over 30 days at various temperatures. Craters formed by ignition of threat ammunitions require repair of both the pavement surface and the base material below. Not only do the current strategies and materials for these full-depth repairs place soldiers performing the repairs at risk for extended times, but the repairs themselves also perform poorly under traffic. The proposed material should consider hydro-sensitive, as the structure of the material and the critical properties for performance changed when the foam reacted in the presence of water. This issue will be addressed through contingent actions, such as isolation from water sources and adjustments to the formulation in Phase II development efforts. On a follow-on Phase-II project this technology will be commercialized by a leading concrete manufacturer who is very much interested in this technology.
