1.4 Checks during paving
The following points must be constantly observed during paving:
Paver function
- Screed heater
- Tamper and vibration
- Engine oil and hydraulic oil temperature
- The screed parts must be retracted and extended in time when obstacles are in the
way
- Uniform material transport and distribution or supply to the screed; may require cor-
rections to settings of the material switches for conveyor and auger.
A
See the section ”Malfunctions” when paver finisher functions fail.
Quality of the layer
- Layer thickness
- Slope
- Evenness in the driving direction and at right angles to it (check with 4 m levelling
rod)
- Surface structure/texture behind the screed.
