Self-Leveling Screed
• Screed is free to rise & fall
• Constant line of pull when set up properly
• Smooth surface over irregular grade
Understanding the Paver
Screed Set Up
•Check & Adjust flight screws• Check & Adjust Extensions• Check & Adjust crown • “Zero Out” electric screws• Set Up & Check Automatic Grade Controls• Set end gates to meet job requirements• Spray screed BEFORE lighting burners
2/23/2016
40
Setting up the Screed
• Make sure that: • Your extension is in line
with your main screed• Your angle of attack is
consistent on both sides• Your crown/valley is set
to the correct value• Tow point adjustments
are at “0”
Setting up the Screed
2/23/2016
42
Why “0” Out Your Tow Points?
• Keep the paver in good condition
• Scheduled inspection & maintenance
• Follow maintenance and safety guidelines
Understanding the Paver

43
Tilt Hopper Pavers
Which Commercial Paver Size Is Right For You?
Conveyor Pavers
Talk To Your Manufacturer’s Rep About Proper Sizing For Your Scope Of Work
Factors to Consider
•Weight•Will the Paver be to light or too heavy for the jobs you
plan to do?
•Length•Can the machine perform the functions asked of it if it is
too long for the job?
•Maneuverability•Will you need to perform tasks such as paving around
islands or parking space cutouts?
•Trailer-ability•Is your trailer big enough to haul the machine?
•Conveyor Width•Can the machine deliver the asphalt required without
taxing the components?

Which Undercarriage Is Right For You?
Many Options Are Available Including Steel, Poly Pad and Continuous Rubber Track. Each May Be an Advantage (Or Disadvantage) Depending On Your Scope Of Work

50
Starting The Pull
• Find The “Null” Point In Your Screed
• Crank Until Resistance is Felt to Introduce Angle Of Attack
Factors Affecting The Screed
The Paver/Screed Operator must understand what is happening
each time he makes a change in speed, angle of attack and head of
material
2/23/2016
51
Flight Screws
Tow Arm
Endgate
Extension
Parts of the Screed
Factors Affecting The Screed
• P – Pulling Force• W – Weight of the Screed• C – Compacting Force• A – Rotation of the Auger• M – Resistance of the Material• R – Reaction of the Asphalt
2/23/2016
52
Factors Affecting The Screed
Constant Speed
• Shear factor is constant
• Depth remains constant
Factors Affecting The Screed
Increased Speed
• Shear factor decreases
• Depth decreases
2/23/2016
53
Factors Affecting The Screed
Decreased Speed
• Shear factor increases
• Depth increases
Screed Adjustments
• Increase angle of attack
• More material passes under screed
• Screed rises to new level
2/23/2016
54
• Screed reaches new height
• Achieves equilibrium
• Resumes original angle of attack
Screed Adjustments
Screed Reaction Time• Screed reacts to change in angle of attack over 5 tow arm
lengths• 65% of change occurs in the first tow arm length• 35% of change occurs in the last 4 tow arm lengths
Screed Adjustments
2/23/2016
55
Factors Affecting The Screed
• Correct Head of Material
• Constant resistance
• Constant depth
Factors Affecting The Screed
• Head of Material Decreased
• Resistance decreased
• Depth decreases
2/23/2016
56
Factors Affecting The Screed
• Head of Material Increased• Resistance increased• Depth increases
Controlling Yield
• Do not correct based on one measurement
• Make series of measurements
• Average measurements
• Correct based on average
• Improves rideability & yield
2/23/2016
58
“Hot” Joint Construction
• Keep roller off edge of
• previous pass 6” to 8”
• Set end gate flush with screed
• extension & completely flat
• spray end gate frequently
• Overlap previous pass 2” to 3”
• Adjust up or down with manual
• or electric screw
• Use Automatic Joint Matcher
“Cold” Joint Construction
• Rolled or “Cold” Joint - Allow 1/4” per Inch for compaction
• Overlap cold joint by 1”-2”

End with a Daily Routine
•Remove all excessive Asphalt from Paver
•Clean and Spray Components
•Run Conveyers and Spray with Release Agent
•Spray Auger Chains and Conveyer Chains
•Add Fuel
•Add Propane
•Grease Necessary Parts
Transport
• Always Back Your Paver On The Trailer
• NEVER Let The Screed Bump the Trailer or Drag The Ground – Loading Boards May Be Necessary
