Ragged edges and gaps in line • Material temperature is too low
• Thermolazer
™
speed is too fast
• Raise material temperature
• Wait for change in ambient condi-
tions to remove moisture
• Reduce Thermolazer
™
speed
Swollen rounded line • Material temperature is too high • Lower material temperature
Material shadows on sides • Uneven road surface
• Die is not evenly riding on sub-
strate
• Apply to even road surfaces
• Remove debris from screed box
lever rod
• Inspect/replace damaged screed

ence application
• Use correct application methods
(for example, try locking swivel
wheel)
Cracks in line • Cracks in road surface
• Temperature stress from
overheating
• Material applied too cold
• Material applied too thin
• Repair cracks
• Lower temperature in material
• Increase material temperature
• Slow Thermolazer

speed to
apply thicker material
Rough edges and lines in surface • Material temperature is too low
• Material is overheated or scorched
• Moisture in road surface
