Asphalt Overlay Program Overview – Presented by City of Plano
• Why Asphalt Overlay
• Benefits
• Preservation
• Water Intrusion
• Significantly fewer defects when overlay added to concrete repair
• Ride quality
• Noise reduction
• Aesthetics
• Aesthetic Consistency
• Life cycle analysis

Asphalt Overlay Program Overview – Presented by City of Plano
• Why Asphalt Overlay
• Repair and overlay vs. concrete reconstruction
• PCI Scores Dictate Maintenance Not Replacement
• Life Cycle Cost
• Construction Disruption to Public
• Time for Construction
• Phasing for Construction

Asphalt Overlay Program Construction Methods –Presented by TexasBit
• Material & Equipment Selection
• Level-up mix
• Surface Mix – Ultra-Thin Overlay, TOM, CAM, Type D, Super-pave, MAC
• Spray Paver vs. Hot Applied Membrane vs. Conventional
• Benefits of Recycled Materials – how they help asphalt performance
