Tire Module Systems in Shore and Harbor Protection

Experiment testing has indicated the potential value of using discarded tires as a construction material for low cost shore and harbor protection. The modular assembly methods and use of available connecting materials are examined for an 18-tire module. Engineering design parameters, material cost, and field tests for both floating tire breakwaters and tire revetments are summarized. Floating tire breakwaters are described and have provided wave attenuation in marinas and small harbors in both salt and freshwater. Descriptions of two tire revetment test sites on the Great Lakes are presented. Limited monitoring efforts have shown that the concept of tire revetment mats seem to hold promise as a low cost approach to certain shore erosion problems.
