Residual Shear Test
Job No.: 5741
Project: Monument Dam -#06/26-067
Boring No.: SB-06 Sample No. 2 Depth: 45-47 Test Date: 8/17/2006
Location: Sample Type: Jar Date Re orted: 8/22/2006
Soil Type: Lean Clay w/sand (CL) Shear Rate
0.0009 (in/min)
Remarks: Sample ground down through the #40 sieve and sand and gravel removed. Specimen was then
prepared to a Liquidity index between 1.1 and 1.2. Specimen was incrementally loaded to 7 tsf then unloaded to

1.0 tsf. Specimen sheared until readings were consistent
