Test Method Title
Standard Test Method for Evaluation of Durability of Rock for Erosion Control Using Sodium Sulfate or Magnesium Sulfate
Description of Test
Erosion control rock samples are trimmed into saw-cut slab specimens. The trimmed slabs are oven dried to a constant mass. The specimens are repeatedly immersed in saturated solutions of sodium sulfate or magnesium sulfate followed by oven drying. At the completion of the test, the percent loss by mass for each specimen set is determined. A visual examination of the slabs is performed at the end of testing. The type of deterioration and changes to previously noted planes of weakness are recorded.
