Proper Loading Sequences

Single Dump Load will Break and Run

Tarp Every Load

Effects of No Tarp

Exit the Paving Area to the

Cleanout Area

Don’t Clean Trucks in the Area To Be Paved!

stop many

problems

before they

start

2/23/2016

26

Proper Training

• You must demand a

qualified startup or

re-training

whenever you

require additional

training

Start with a Daily Routine on ALL Equipment

Paving Width

• SCENARIO- You have a 30’ pass to pave. What is the best way to pave to achieve the highest quality results?

• ANSWER – 3 - 10’ passes will result in a faster and higher

quality job.

39

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”

Why “0” Out Your Tow Points?

Why “0” Out Your Tow Points?

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

2/23/2016

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?

2/23/2016

44

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

Tack CoatingWhy Tack Coat?

2/23/2016

45

Tack Coating

Tack Coating

• How Much is Enough?• How Much Is Too Much?

95% of your surface must be tack coated!

47

Mistakes Are Expensive

Starting The Pull

2/23/2016

48

How Deep To Pave

You must Pave At Least 3x The Size of Your Nominal Aggregate

Starting The Pull

How do we start at the right depth?

• Start from 0

Starting Blocks

2/23/2016

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

57

Joint Construction

• Quality joints are no accident

Joint Construction

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”

Your Review for Success

Your Review for Success

4. Call The Plant• Know Your Tonnage Required and Communicate it• Know Your Trucks and Their Turnaround Time

5. Check Your Equipment• Fill Out Inspection Forms (Fix any Abnormalities)• Check Fluids and Gauges• Reset Screeds• Inspect Towpoints

2/23/2016

77

6. Pave By The Numbers• Use a Wooden Straightedge• Use a Temperature gun to monitor asphalt• Constantly Monitor Yield• Coordinate Trucks as job progresses taking

weather into consideration• Designate Truck Clean Out Area

7. Inspect Job Afterwards• Walk/Ride Joints• Make a Punch List Before Customer Does
