Abstract:

The U.S. military must have the ability to rapidly deploy troops and equipment anywhere in the world as part of a contingency operation. Recent military operations have highlighted the critical need for rapid repair procedures and materials for military use on substandard, in-theater airfields. The U.S. Army Engineer Research and Development Center is currently addressing these problems through a 6-year demonstration-based research and development program called JRAC Joint Rapid Airfield Construction. This study involves the development of a method using rapid setting grouts and recycled concrete pavement RCP to repair portland cement concrete pavements. A laboratory study was conducted to evaluate material properties in order to gain an understanding of expected field performance. Eight full scale repairs were constructed using two rapid setting grouts, two types of equipment, and two concrete slabs. The repairs were successfully trafficked with simulated C-17 aircraft wheel loads to verify the structural capacity and, ultimately, the procedures.
