CMP 305 exam with complete solutionsMontmorillonite is known to have what properties? - ANSWER- high volume
changes and weak bonds
phase diagram displays what? - ANSWER- relationship between volume and
weight of a soil bunk
does clay absorb more or less water than other types of soils - ANSWER- more,
clay attracts water
when is angular-granular soil at its highest shear strength? - ANSWER- when it is
in a dense condition and has a low void ratio
of the four soil groups which has the greatest expansive characteristics with
water? - ANSWER- clay
load-ability - ANSWER- measure of difficulty in excavating and loading a soil
what kind of soil has high load-ability - ANSWER- loose, granular soil
what kind of soil has low load-ability? - ANSWER- compacted (frost), clay, rock
classification for a fine grained soil being a clay or silt is based on what? -
ANSWER- plasticity, not particle size
soil with best engineering properties? - ANSWER- angular, high shear strength,
good distribution of particle sizes so they can be packed together
well graded soil - ANSWER- Soil with a variety of particle sizes that tend to form a
denser structure
poor graded soil - ANSWER- uniform particle sizes, can't be packed into
eachother
, the smaller the void ratio (denser the material) - ANSWER- the greater the
compressive strength of the soil resulting in low compressibility of soil
spoil - ANSWER- removed soil
coarse soil in loose condition (like after initial placement) is more likely to have
what if subject to vibration? - ANSWER- quick volume reductions and loss of
strength
gap graded soil - ANSWER- lots of large size particles and lots of small size
particles, no inbetween
is it better to have soil that is layered or mixed together? - ANSWER- layered
coarse grained soil - ANSWER- non-cohesive, sand and gravel
fine grained soil - ANSWER- cohesive, clay and silt
2 lab tests for engineering properties of soil - ANSWER- sieve and sedimentation
will coarse grained soils pass the 200 sieve? - ANSWER- no
more than 50% by weight that passes 200 sieve? - ANSWER- fine grained soil
anything that does not pass the 200 sieve with 50% by weight? - ANSWER-
coarse grained soil
what would pea stone be classified as? - ANSWER- poorly, uniform, graded soil
liquid limit? - ANSWER- expressed in % of dry weight, point at which soil will
begin to flow, uses standard shake test
plastic limit? - ANSWER- moisture content in % at which the soil begins to
crumble when rolled into a 1/8th inch diameter ball
bank - ANSWER- material in its natural state, referred to as "in place", unit" BCY
bank cubic yards
unit soil weight depends on - ANSWER- soil type, soil moisture, soil compaction,
density
