• <br />• <br />fragments. The exact composition apparently depends on whether <br />the origin of the fill is a cut in colluvium or in bedrock. <br />The crushing and screening Level Eill at the location of <br />Boring B-3 was principally clayey material. Test pits ex- <br />cavated at representative Locations within other fills in- <br />dicate that a higher gravel content is probably typical for <br />those other fills. This suggests that the shear strength para- <br />meters developed from triaxial tests on samples taken from <br />Boring B-3 may be conservative when applied to other fills. <br />Boring B-3 indicated the crushing and screening level <br />fill to be generally soft to medium stiff for the upper <br />30 feet, becoming generally medium stiff to stiff below this <br />level. This suggests that this fill has been constructed with- <br />out systematic compaction, as is believed to be the case for <br />all other fills as well. The water content of the fill varies <br />between about 10 % and 20 %. <br />• ~~ <br />'I - 1"_' - <br />GE6MYDR0 CONSULTING.INC. <br />
