OVERLAY OF LARGE, PLACED QUARRYSTONE AND BOULDERS TO INCREASE RIPRAP STABILITY

This report describes the wave tank tests and field performance of a single layer of large armor stone used as a protective overlay on underdesigned riprap. The resistance of the overlay to wave attack was determined by small-scale model and prototype-scale wave tank tests at CERC. A stone overlay concept was successfully used to repair a damaged riprap revetment on Oahe Reservoir, South Dakota (App. A). Design information and an example problem (App. B) are presented to demonstrate application of the overlay concept to both revetment repair and original construction. (Author)
