CH. 6 SOIL COMPACTION Flashcards
1
Q
SOIL STRUCTURE
A
CONSISTS OF ROCK PARTICLES, AIR VOIDS AND WATER.
2
Q
OPM-OPTIMUM MOISTURE CONTENT
A
RIGHT AMOUNT OF WATER FOR SOIL COMPACTION
3
Q
DENSITY
A
WEIGHT TO VOLUME RATIO-MORE SOIL PARTICLES PER CUBIC FOOT, THE GREATER THE WEIGHT, AND THE GREATER THE DENSITY
4
Q
DENSITY TESTS
A
PROCTOR TEST
SAND CONE TEST
NUCLEAR DENSITY TEST
5
Q
PROCTOR TEST
A
TO ATTAIN MAXIMUM DENSITY, SOIL MUST HAVE THE CORRECT MOISTURE CONTENT
6
Q
SAND CONE TEST
A
COMPARES DENSITY OF FIELD SAMPLE TO DENSITY OF PROCTOR SAMPLE
7
Q
NUCLEAR DENSITY TEST
A
GAMMA RAYS DIRECTED AT A MASS, SOME PASS THROUGH AND SOME ARE REFLECTED BACK
8
Q
2 MOST COMMON METHODS OF COMPACTION
A
PUDDLING
WEIGHT + VIBRATION
