S&T Project 8284: Cracked Embankment Erosion Test 9 Video File
The title of this test was Cracked Embankment Erosion Test (CEET) 9. This test took place from October 2 to 5, 2017. The material used was Highland Clay and had a Plasticity Index (PI) of 27, classified as a lean to fat clay (CH/CL), had 95.4% passing the No. 200 sieve, the maximum unit weight was 97.7 pounds per cubic feet, and a moisture content of 23.5%, 2.8% wet of optimum. The embankment was constructed using a pneumatic tamper to 90.8% compaction at optimum with approximately 1-inch lifts over a three-week period. The average void ratio was 0.76 and the average degree of saturation was 83.5. The embankment was 10 feet long (upstream to downstream), 1.5 feet wide, and 3 feet tall. The embankment was built using a stair step construction. The steps were removed prior to the test. The surface was not scarified prior to testing. The test crack was a 3/8-inch continuous crack both vertically and horizontally. Approximately halfway through the test, the reservoir level is increased to overtop the embankment long enough for a speed test to be conducted, at which point the reservoir level is decreased to no longer overtop the embankment. Speed tests were conducted throughout the experiment.
