Comparison of Predicted and Performed Durabilities of the Armourstones from some Black Sea Rubble Mound Breakwaters
Black sea coast line is a hazardous region in Turkey especially in winter due to the dominant wave action. Therefore, rubble mound breakwaters used as ship shelters are vital structures especially for the fisherman. Construction of the breakwater requires good quality durable armourstones. Due to the nature of the rubble mound breakwaters, the armourstones with various sizes and types are used in the construction of these structures. The deterioration of these armourstones with time may result in the failure of the breakwater. In this study, various field and laboratory tests suggested in CIRIA/CUR (1991) and Rock Engineering Rating System-RERS (Lienhart 1998) of five armourstones (mainly limestone, andesite and sandstone) are performed. The test results are compared with their site performances in breakwaters and used to evaluate the suitability of the test results. Among the studied stones, the sandstone displays very poor performance. The others are found to be relatively good. Based on the data obtained, it is observed that some of the physico-mechanical parameters of the armourstones are good at predicting the long-term field performance of the armourstones. This paper will discuss the parameters to be used in the durability assessments of the armourstones.
