FILL TEST FILL c,DATE 5/27/76 PROJECT TITLE: WATERFORDJES UNIT NO .3 CONTRACT NO W3-NY-4 1.0 PURPOSE This procedure outlines a means to 'detennine the optimum construction techniques for the compaction of the backfil' material to be used around the Plant Island St ructure. ,
4 2.0 SCOPE The scope of the procedure will cover the construction and compaction of a test fill including compaction field testing, data compilation, tabulation and analysi s.
The final analysis of the data will result in a recomendation as to the number of passes required to attain density requirements.

6.1.1 During the initial stages of the backfilling operation a quantity of Class A material, sufficient to cover an area of about 100ft.
by 20 f t.', shall be placed in the condition in which it would normally be dumped.from trucks. Th.e thickness of the meterial which is put down shall be 15 inches before compaction. The detailed geometry of the test fill is shown in Appendix A.
6.1.2 Compaction shall be achieved using a* self-propelled 12 ton dynamic force vibratory ' drum roller. Starting with four passes, and increasing compaction in sets of two passes, the test fill shall be compacted as shown in Appendix A. On each set of two passes, the .following tests shall be performed!

An analysis of the test curves , will be made by the Engineer and his interpretation of the results shall govern. The Engineer may also, at his discretion require any mod- 4 ifications in the testing program as may seem neces,sary in order to accompli sh the desired results. 6.3.1 Af ter the Engineer has made his review of the results of the tes.t program, all, work associated with the installation and compaction of the Class A Backfill shall. follow the procedures used during the testing program as closely as practicable. 6.3J The _use..of backfilLmaterial.of-a- different-type, or-from a--differen C" ,- source, or the use of a different type or model of compacting equipment, will require new tests to be made to determine the'
. proper number of passes. .
