• Abstract:
  Laboratory tests were performed on compacted specimens of 10 embankment materials specified by the Utah Department of Transportation using both standard-size and large-scale equipment. The tests consisted of preparing each test specimen to predetermined values of density and water content, and measuring the settlement or heave of the specimen when loaded to simulate the weight of the embankment material above a particular depth within the embankment, and by adding water to simulate water infiltration into the embankment. Test specimens were compacted using a method appropriate for the type of material being tested that also simulated the type of compaction generally used during construction of an actual embankment. Using the results from these tests, settlement or heave of a 30-foot-tall typical embankment was calculated for the different materials, densities, and water contents studied. In addition, recommendations were made to change some aspects of the current UDOT specifications for bridge approach embankment specifications based on the results of the settlement/heave calculations.
