Intro to Earthmoving

The first three steps in stabilization are to determine soil properties, the degree of compaction needed and

• whether it will create runoff problems

• the amount of binder required

• whether rock particles are too large

• the percentage of moisture needed

the removal of earth from a large, deep excavation with vertical sides is called

• highway excavation

• bulk-pit excavation

• channel excavation

when large quantities of earth need to be moved 15000 feet, the equipment selected would be

• backhoes

• Front end loaders

• scrapers

• excavators

the traffic control supervisor on a construction project is responsible for

• designing the traffic signs

• directing the traffic flow

• controlling operating conditions at the loading and dumping sites

• evaluating the equipment drivers

NPDES storm water permit must be obtained if

• more than one acre of land will be disturbed

• storm water drains have not been installed

• soil erosion is likely to occur

• work is scheduled to be done on a rainy day

What is the reason for analyzing the cycle time of a piece of equipment

• it establishes the equipment's maintenance intervals

• allows the contractor to estimate how long a job will take

• determines how fast the operator can drive

• provides documentation about operator safety

site access should be limited to authorized persons

• only at night

• during the day

• during work

• all the timed

Red, orange, and green markers are types of

• underground utility markers

• property boundaries

• right of way markers

• cut and fill grade stakes

over the road hauling involves hauling materials

• on public highways

• across the work site

a bottom dump truck

• can sump material into a spoil pile

• can dump fill over an embankment

• is best for dumping fill material in windrow
