Abstract
The Department became aware of fill slippage on I 64 some 300 feet east of mile post 188 during the summer of 1967. In September of that year Mr. L. E. Richardson, Division of Maintenance, and Mr. Gordon D. Scott, Division of Research, made an inspection of the area. Mr. Scott reported cracking of shoulder, movement of the guard rail, and a failure in the berm along the toe. However, subsequent inspections showed the slip to be stabilizing by itself until late in 1970 when some additional movement was observed. In January of 1971, the most conspicuous pavement failure was located almost directly above the berm failure. It appeared that the berm failure may have affected the roadway failure; one crack was observed in the embankment surface about midway between the top of the eastern roadway shoulder and the top of the berm. The embankment slip appeared to have been triggered by deep erosion along the western margin of the fill and toe of the berm and extending from station 282+00 to station 285+50. The deeply eroded ditch was approximately 3 to 5 feet in depth and carried water from a median drain, station 282+00, and a 24-inch cross-drain at station 282+50.
