well graded clean sands; gravel-sand mixes - ✔✔SW
poorly graded clean sand; sand-gravel mixes - ✔✔SP
Silty sands; poorly graded sand-silt mixes - ✔✔SM
Sand-silt clay mix with plastic fines - ✔✔SM-SC
Clayey sands; poorly graded sand-clay mixes - ✔✔SC
Inorganic silts and clayey silts - ✔✔ML
Mixture of inorganic silt and clay - ✔✔ML-CL
Inorganic clays of low to medium plasticity - ✔✔CL
Organic silts and silt clay, low plasticity - ✔✔OL
ICC Soils Certification test questions with correct answers
,inorganic clayey silts, elastic silts - ✔✔MH
Inorganic clays of high plasticity - ✔✔CH
organic clays and silt clays - ✔✔OH
Types of slope stability - ✔✔Drainage
slope reduction or flattening
structural solutions
chemical stabilization
what would stabilize a slope that has been effected by seepage water? how does this improve slope
stability? - ✔✔Sub- drainage, decreases the saturation of the slope
when a slope begins at vertical cut what is done to stabilize the slope? - ✔✔removing the upper
portions or head of the slope or landslide is the frequently employed technic for reducing the driving
forces that cause the failure to occur
what are red lights on a site? - ✔✔low bearing capacity
settlement
existing uncontrolled fill
slope stability
dangerous seismic conditions
frost heave
constructabilty- piers or piles
proposed significate cut or fill
groundwater problems
foundation red lights - ✔✔design not in accordance with geotechnical recommendations
ICC Soils Certification test questions with correct answers
, foundation location differs from site investigation location
foundation plans not adequate or complete
low bearing capacity not recognized in footing design
compressible or expansive soil on site not anticipated in design
water seepage not anticipated in design
seismic conditions not documented properly in design or calculations
provisions dealing with frost heave not included
retaining structures or basement walls without adequate drainage
underfloor crawl space not vented or drained
when should concrete be placed? and what raises red flags in the design? - ✔✔within 90 minutes of
adding water at the concrete plant
excessive water should not be added at the site, no more the 5 gallons per truck
if air temperatures are higher then 90 degrees and the humidity is less then 25 percent , concrete may
suffer drying shrinkage cracking
concrete should not be placed if air temperatures are 40 degrees and falling unless special cold
weather measures are placed
