Performance Assessment of armoure the Rubble Mound Breakwaters Located in Northern Coasts of Persian Gulf(Boushehr Province)

In this research durability of rocks used in rubble mound breakwaters has been studied. As a part of this research, twelve case studies have been conducted on twelve breakwaters located on the northern coast of Persian Gulf in Bushehr Province (between Naay Band estuary in Assaluyeh Port to Bushehr Port). Moreover, to conduct extensive site investigations, some samples were collected from different cross-sections of breakwaters. In each case, standard quality-control tests were carried out on samples and test results compared with different authentic standards. Furthermore, thin sections of each sample were prepared and classified by petrographical microscope. In addition, actual and natural properties of the samples were examined with respect to environmental conditions.
