Total questions: 10
Worksheet time: 9mins
What is soil improvement?
improving the chemical properties of the soil
improving the engineering properties of the soil
process to rearrange soil particle
improving base or sub-base layer of soil
Following is a purpose of the compaction in the field, EXCEPT
increase strength and stiffness of the soil
prepare a level surface for construction activities
reduce the moisture content
Control swelling and shrinking
The mechanical modification (compaction) of cohesive soil can be done by
Dynamic compaction
Vibro-replacement
Roller
Vibro-flotation
Following are the benefits of surcharge preloading and vertical drain in soil improvement, except
to remove air void in the soil
to shorten the consolidation time
gain in strength
to accelerate consolidation
Which statement describes chemical stabilization
The process of reducing the density of soil and making it more stable and durable.
Involve the treatment of soil with chemical stabiliser by change the texture of the soil
Involve treatment of the soil with chemical stabiliser, when it is added to the soil, would result in a chemical reaction to the soil that will physically interact with it and change its properties.
The process of altering properties of soil by changing the gradation through mixing with tire chip to improve strength and durability of soil
Soil compaction can be described as a method to increase maximum dry density via
compaction of soil particle so it will move into densely pack position
rearrangement of soil particle
by adding moisture content at optimum percentage
all of them
What is(are) the different between Standard Proctor test and Modified Proctor test
layer of soil in mould
weight of hammer
compaction effort
all of them
Modified Proctor Test will increase the soil strength and in the same time will reduce amount of water to be used
TRUE
FALSE
Modified Proctor Test has higher compaction effort
TRUE
FALSE
To observe strength required achieve at field, these are the filed density test that can be carried out, EXCEPT
sand cone method
ballons den meter
standard proctor
nuclear gauge
