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!
Preventative Maintenance or
Corrective Maintenanceor
Both
What is Pavement Preservation?
Pavement Management System
What do you do?Pavement Condition Index (PCI)
Visual InspectionMaintenance Experience
Rehabilitation - Performance HistoryInitial Cost Dictates
What about the pavement condition?
Pre-maintenance; What about Patching?
Pre-maintenance; What about Crack Sealing?
Pavement Preservation – Scrub Seal Application
Pavement Preservation - Slurry Seal Application
Pavement Preservation - Micro Surface Application
Pavement Preservation - Chip Seal ApplicationPavement Preservation - Chip Seal Application
Pavement Preservation - Hot Mix - Thin O/L Application
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!
Partnering ConceptsCost Issues/Considerations
Lets Try to Reduce Initial Cost!
a) Inter-Agency Agreementsb) Concurrent Biddingc) Tag-on Contracts d) Renewable Contractse) JOC’sf) Specificationsg) Early Biddingh) Project Schedulingi) Construction Criteriaj) Materials Indexing
Inter-Agency Agreements
Is this option possible?
What are the liability issues for the lead agency?
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
Renewable Contractsand
JOC’s
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?
Discussion!
