Fault Phenomenon: Dynapac F300W paver the paved road surface shows waves; inspection reveals the screed base plate is depressed in the middle.

Troubleshooting Process:
– Checked base plate: front edge wear over 3mm.
– Checked material: insufficient base plate hardness.
– Checked material: mix highly abrasive.
– Checked attack angle: excessive working attack angle.

Root Cause: The front edge of the screed base plate is worn and blunted over time, and has become depressed, changing the material flow resistance and deteriorating paving smoothness.

Required Parts: Repair or replace screed base plate.
