Repair, Evaluation, Maintenance, and Rehabilitation Research Program: Prototype Experience with the Use of Dissimilar Armor for Repair and Rehabilitation of Rubble-Mound Coastal Structures
Abstract
A survey of existing Corps structures that have used dissimilar armor for repair and rehabilitation was conducted. The survey was accomplished by search and study of project index maps, reconnaissance reports, special reports, and in conjunction with other work units and follow-up visits to the districts and divisions for first-hand discussions and observations. Results show that in all cases selection of the dissimilar armor type and weight was based on design guidance for new construction, prototype experience, engineering judgement, inferences from model tests of similar structure, or site-specific model tests rather than guidance specific to evaluating the interfacing and stability response of the dissimilar armor. It is reasonable to conclude that the guidance needed for use of dissimilar armor will become more critical in future years as rehabilitation of major break-waters and jetties becomes necessary to extend their project life. Keywords: Coastal engineering; Rubble mound breakwaters.
