Abstract: This report documents the fmt evaluation of CORE-LOC™ (Core-Loc) concrete armor units to repair dolos-armored breakwater slopes. The U.S. Army Engineer Waterways Experiment Station is investigating the Core-Loc armor unit because of its superior structural and stability characteristics and its ability to interlock with dolosse. The study reported herein is based on the results of three-dimensional physical model testing. Degradation of a dolos-armored breakwater head section is physically modeled at small scale. Modeling was done in such a way as to reproduce damage as realistically as possible without the added expense of actually scaling the structural strength of the armor units. For these tests, once an armor unit fully displaced from its original position, it was considered broken. Because of time and budget constraints, this investigation focuses on the performance of Core-Loc when used to repair armor using the spot repair method. Future tests of Core-Loc-repaired dolos slopes using the V-notch method are planned.
