ICC Soils Special Inspector - Code

Given: For a sand cone density test, the volume of the hole = 0.05 cu. ft.; the weight of the excavated soil = 6.6 lb.; the water content of the soils = 7.5 percent; and the maximum dry density of soil = 134.6 lb. per cu. ft.
A. 85 B. 95 C. 91 D. 98
If the surface under a nuclear density gauge is irregular, which of the following should be done?
A. Use backscatter mode B. Moisten the surface and reshape C. Fill the irregularities with 1/2 to 1 in. of filler D. Fill the irregularities with maximum 1/8 in. of filler
Given: Field dry density = 111.0 lb. per cu. ft.
A. 86 B. 87 C. 89 D. 90
When performing a nuclear gauge density test, oversize rocks that are not accounted for in the laboratory Proctor test may cause the density to:
A. be lower B. remain the same C. be higher D. remain the same but alter the water content
