Loss slake index evaluation and its applicability to marl
Some of the main soft rock characteristics are relatively rapid deterioration and degradation of strength when soft rock is exposed to atmospheric agents. For this study marl samples from Eocene flysch formation found in Dalmatia region in Croatia are selected. When weathered, marl tends to degrade into a fine-graded soil-like material with high compressibility and low shear strength. Current methods of predicting behavior of marl (i.e. slake durability index) when exposed to weathering process are sometimes unreliable, therefore there is a necessity to establish new durability index. This study is an effort to try to implement loss slake index developed by Bryson et all. on shale samples as a new index for marl. In this case samples are taken from a coastal area, therefore information about natural moisture level could not be used to make a valid correlation analysis. Results show that loss slake index, as a method of evaluating durability, could be also applied on marl.
