Abstract: The Gold Coast of Queensland, Australia, is in an exposed coastal zone that is now suffering from major problems with both the availability of suitable large rubble armour and its durability in service. There is an ongoing demand for rubble amour for protective revetments, but the available supplies can barely meet the demand and what quarry rock that can be attained is seriously affected by quarry-blasting induced subsequent fracturing in service. These circumstances have required a review of rubble structure construction procedures and the development of different methods of rock selection and revised placing procedures within the rubble structures themselves. These factors are discussed in detail in the paper.
