Abstract: After a large rockfall damaged the road and disrupted traffic along the George Washington Memorial Parkway in 2002, the National Park Service was looking for solutions to stabilize the slope against additional large-scale rockfalls while preserving the aesthetic quality of the scenic roadway. Rock gluing, a grouting technique involving the injection of polyurethane resin, was used to mitigate the hazard. Ten years after construction, the rock-gluing solution appears to be performing in a satisfactory manner.
