Best Practice Heat Remove
Focus on constant speed!
Dont outrun your temperature!
Start late, finish late
43
Best Practice HIR Laydown
20 ton rubber tire breakdown for lower temp
Heavy steel finish
Conventional paver for smoothness

Project Selection Factors

• solid base
• min 50mm top lift
• min 5 AC content
• min 25penetration
• Max 19mm agg

45
Design Considerations

• Existing mix and binder properties
• Establish target mix and binder properties
• Determine rejuvenator type and content
• Determine admix quantity and gradation
• Achieve a design VMA
• Achieve design air voids (3 to 5 common)

46
Adding Rejuvenators
47
Admix Options

• Increase air voids
• Reduce filler content
• Improve stability
• Reduce AC content

48
BC EPS Approach

• Contractor for Mix Design and QC
• Penalty and bonus adjustment for
• Gradation
• Smoothness
• AC Content
• Segregation
• Compaction
• Lane Occupancy

49
