- 1What is SOIL SATURATIONHOW MUCH VOID SPACE IS OCCUPIED BY WATER
FULL = 100
PARTIALLY/UNSATURATED < 100 % & > 0%
DRY = 0% - 2WHAT IS CAPILLARITYRISE OF WATER FROM A SATURATED ZONE TO A LESS SATURATED OR DRY ZONE
- 3WHAT IS FROST HEAVEVERTICAL EXPANSION OF SOIL CAUSED BY FREEZING WATER
- 4In A sieve Analysis - A Uniformity coefficient of 3.5 would indicateThe soil is uniformly graded
- 5In a Sieve analysis - A uniformity coefficient of 7.2 would indicateNon uniformly graded, it can be
Gap graded or Well graded
(dependent on Cc formula) - 6Our sieve analysis is Gap or well graded (Cu over 4), What formula is used to know if its Gap or well graded?coefficient of curvature
Cc = D30^2 / (D10 X D60) - 7What is the principle of a hydrometer test?Different soils settle at different velocities. The bigger the particle the quicker it will settle.
- 8When should a hydrometer test be used vs Sieve test?A Hydrometer test is used for particle sizes less than .075
- 9What are the three atterberg limits and which has the higher MC%Liquid limit LL

- 11Plastic limit is determined byRolling

Used in MC%, Plasticity test, sieve
Undisturbed
Lab testing, strength, settlement - 14While in situ borehole drilling samples are typically taken every ___ m1.5 m
5' - 15In Borehole drilling which type of tube is used to collect undisturbed samples Which type of tube is used for disturbed samples?1. Shelly tube.
