Abstract: An extra fill on a revetment was constructed by using mechanically dewatered clay (MDC) made from dredged material in the third area of the Shinmoji-Oki disposal pond (S-3), Japan, in 2011. Since MDC is an artificial material, its long-term stability has not been confirmed. To understand the long-term stability of the constructed revetment, mechanical tests, such as box shear tests, were conducted on block samples taken from two designated areas of the extra fill on the revetment over the 10 years since its construction (2011-2020). As a result, it was confirmed that the shear strength under certain overburden effective stress sufficiently satisfied the value assumed at the designing stage and the strength properties did not change much after 10 years, although the strength constants varied.
