Partnering & Pavement Preservation -A Contractors Perspective-
AACE Meeting June 05, 2008
Mormon Lake, Arizona
Before you can Partner a Decision needs to be made as
to what Pavement Preservation Strategy or
Strategies will be Utilized!
Pavement Management System
What do you do?Pavement Condition Index (PCI)
Visual InspectionMaintenance Experience
Rehabilitation - Performance HistoryInitial Cost Dictates
Pavement Preservation - Multi-layered System ApplicationPavement Preservation - Multi-layered System Application
Don’t Expect Miracles• Pre-maintenance is Mandatory
• Consider Climatic Region (Const. Date)
• Binder Design Variables
• Mix Design Variables
• Construction Procedures (Details)
• Consider Traffic Conditions
• DON’T LET THE VARIABLES GET YOU DOWN!

Concurrent Bidding PracticeAsphalt-Rubber Chip Seal Cost Comparison
Example:
Individual Project Cost - $ 4.87 per s.y.* Total square yards = 68,800
Partnering Project Cost - $ 4.23 per s.y.* Total square yards = 404,000
Tag-on Contract
Communication - Tag-on Usage Unknown!* Lead Agency Price to all Participants
Communication – Tag-on Usage Known!* Similar Pricing as Concurrent Bidding
Specifications – Consistency!
Early Bidding - Contractors are Hungary!
Project Scheduling - Start and Cutoff Dates?
Construction Criteria - Production Limitations!
Materials Indexing - Equality at Bid Time!
Additional Cost Considerations
Agency:• Budget and Fiscal Year• Project Size• Pre Maintenance Costs
Contractor:• Asphalt Cement and Fuel (Big Cost)• Mobilization Costs
• Scheduling & Construction (Mother Nature)
• Partnering Risks!• Extended Warranties?
Did You Know:When PG Asphalt Cement Rises $100.00 per ton,
The Per Square Yard Cost of a Slurry Seal Rises-An Average of $0.14 Per Square Yard.
The Per Square Yard Cost of a Micro Surface Rises-
An Average of $0.22 Per Square Yard.The Per Square Yard Cost of a Chip Seal Rises-
An Average of $0.25 Per Square Yard.The Per Square Yard Cost of a Hot Mix O/L Rises-
An Average Cost of _______ Per Square Yard?
