Paver Operation


Operational principles of the screed

Operational Principles of the Screed

  • Self-leveling concepts

  • Screed response versus distance

  • Forces acting on a screed


Main forces acting on screed

Main Forces Acting on Screed

  • Speed of paver

  • Head of material

  • Angle of attack

  • Other forces

    • Pre-compaction

    • Screed weight
