The total number of passing tests <br />recorded corresponds to a frequency of 1 test per 318 cy, which satisfies the specified <br />minimum required frequency of 1 test per 500 cy. Also, 11 subgrade/buttress fill soil samples <br />were collected at the nuclear test locations for microwave and oven moisture content <br />determination, to check the accuracy of the nuclear gauge. The specified frequency for this test <br />was 1 per 45,400 cy; the actual frequency was 1 test for every 5,000 cy. Summaries of the field <br />moisture -density tests can be found in Appendix C. <br />• Upon completion of the subgrade/buttress fill soil placement on the slopes, the Contractor <br />11 Geo -Logic <br />ASSOCIATES <br />
