CMP 305 Exam| Questions with 100%Correct Verified answers
soil consists of - ✔✔- soil, liquid, and gases
compaction of soil - ✔✔main focus is to reduce amount of liquid and gas
rock types - ✔✔igneous, sedimentary, metamorphic
Igneous - ✔✔molten rock, magma or lava
- stable at earths core
- breaks down when exposed to air, water, freeze thaw
- high silica: sand/gravel (3 dimensional)
- good construction material, high load bearing capacity.
sedimentary - ✔✔accumulated deposits of soil particles
- pressure from weight, compress and consolidate creating strong bonds
- usually underwater
- ex. shale, limestone, sandstone
metamorphic - ✔✔change = combination of heat and pressure
- ex. limestone to marble
- ex. sandstone to quartzite
- combinations of igneous and sedimentary
- breaks down through weathering
,weathering process - ✔✔- mechanical
- chemical
Mechanical weathering - ✔✔physical breakdown: rain, wind, running water
- coarse soil particles: sand gravel
- 3 dimensional
Chemical weathering - ✔✔reaction of rock and materials from
exposure to atmosphere, temp, water.
- 2 dimensional : crystalline
- very small particles : clay, silt
Soil Deposit - ✔✔origin and type
- residual
- transported
residual soil deposit - ✔✔formed form weathered rock or accumulation of
organic material
transported soil deposit - ✔✔moved from their place or origin, gravity, wind, water
Soil Composition: engineering properties of soil - ✔✔strength and compressibility
- related ratio of unit volume or unit weight of soil with respect to air or water
, used to determine bearing capacities, soil settlement, and slope stability
soil characteristics - ✔✔size and shape affects material behavior characteristics
- round or sharp edges
- wheel ruts, asphalt waves
3 broad categories of soil characteristics - ✔✔- non cohesive
- cohesive
- organic soil
Non cohesive soils - ✔✔sands and gravels
Cohesive soils - ✔✔clays and silts
Organic - ✔✔Peat, fibrous material
Engineering properties of granular soils are affected by - ✔✔- grain size and shape
- grain size distribution and compactness
- Engineering properties (non cohesive soils) - ✔✔- high shear strength
- good for back fill (little lateral force)
- good foundation material for structures and roads
engineering properties of cohesive soils - ✔✔Desirable
- earthen dams (low permeability)
