2.6.5 Setting the roadway profile
Setting the roadway profile defines the cross shaping of the
paved layer with the purpose to drain water from the road in
a crosswise direction.
The roadway profile is measured in "%" and the positive “α”
and negative “ß” roadway profile is distinguished.
• In case of the positive roadway profile, the centre of the lay-
er lies above the edges of the layer. The roadway drains the
water to both sides of the road.
• In case of the negative (super elevation) roadway profile,
the centre of the layer lies below the edges of the layer. The
roadway drains the water to the centre of the road.
The limit values of the roadway profile are different for the posi-
tive and negative ranges.
• The positive range may be set to a maximum of 3 %.
• The negative range may be set to a maximum of -2%.
Setting the roadway profile:
• Set the roadway profile by setting the screw (1) on the
screed of the machine.
• Ensure that the machine is standing on a level and firm sur-
face.
• To increase the roadway profile, loosen the screw (1).
• To decrease the roadway profile, tighten the screw (1).
• Check the setting of the roadway profile on the scale (2).
