On an articulated ride on roller the 2 half's of the chassis can oscillate or twist what is the purpose of
this? - CORRECT ANSWER It allows each roller to contact the uneven ground and provide compaction
Generally what is the thickness of soil should be compacted before another layer is laid? - CORRECT
ANSWER Approximately 200 mm
What is regarded as a Communist route for poor compaction - CORRECT ANSWER Compacting too thick
layer of material
Name four factors that determine the number of rolling passes - CORRECT ANSWER Machine, weight,
drum width, type of drum, type of material, thickness of material, amplitude setting, and moisture
content
Name three ways in which an operator can maximise their impact on the environment whilst using the
machine - CORRECT ANSWER Efficient use, lower engine speed, well maintained machine, correct
disposal of waste, no spillages of fluids, use biofuels/oils, prior planning for work tasks for efficient use.
, If working in a pedestrianised area state three factors that need to be taken into account - CORRECT
ANSWER Physical segregation of pedestrians from work, machine movement, noise, fumes,dust.

ANSWER They can damage underground services, ruin unspoiled ground, ruin ground prepared for
work, gets stuck due to soft conditions, may stray onto designated routes for other plant.

Usually, three passes
What problems and hazards can soft ground cause to a ride on roller - CORRECT ANSWER It slows the
speed of the roller, it makes it difficult to drive through, the machine can sink, and can get stuck and it
can also tip over sidewards
If travelling on wet soil what effect does this have on the ride on roller - CORRECT ANSWER Grip is
reduced, which may cause loss of control
What is the purpose of a rops cab or frame? - CORRECT ANSWER To provide some protection to the
operating position as far (as reasonably practical) in the event of a overturn of the machine.
