Ground pressure (driving)
The tire contact surface can be changed by means of tire
pressure.
The high pressure on the tires provides a smaller contact
surface (1) and the low pressure on the tire provides a larger
contact surface (2).
The contact surface with the ground is very important for the
compaction result. The total weight divided by the quantity of
2
tires provides the correct pressure for the wheel, according to
the following table:
Low tire pressure - 350 kPa (50.7 psi).
The lower the tire pressure, the lower the pressure on the
contact surface due to larger contact surface.
Is used on lots of loose material
Normal tire pressure - 480 kPa (69.6 psi)
Used for degradation session
High tire pressure - 620 kPa (90 psi).
The higher the tire pressure, the greater the pressure on the
contact surface due to smaller contact surface.
Used for thick layers and finishing sessions
