Monitoring of Nondurable Shale Fills in Semi-Arid Climates
In the research study the performances of three embankments along I-70 in western Colorado were monitored and studied. The embankments were built using the borrow shale material from the adjacent cuts near the roadway. Standard construction procedures were followed with no special shale testing in the field. During the study, the shale samples from all three embankments were tested in the laboratory, and it was found that all three embankments consisted of nondurable shale material. The long-term performance of the above embankments indicates that nondurable shales can successfully be used as embankment fill material in semi-arid climates such as Colorado. Based on the findings of the study, both the jar-slake and the slake-durability tests are highly recommended to identify the shale quality in the field. Based upon the findings of the tests, recommendations could be made to treat the shale as soil-like in thin (8-inch) lifts or as rock-like in thick (2-3 feet) lifts during the embankment construction.
