  1. Partnering & Pavement Preservation -A Contractors Perspective-AACE MeetingJune 05, 2008Mormon Lake, Arizona

  2. Before you can Partner a Decision needs to be made as to what Pavement PreservationStrategy or Strategies will be Utilized!

  3. Preventative Maintenance orCorrective MaintenanceorBoth What is Pavement Preservation?

  4. Pavement Management SystemWhat do you do?Pavement Condition Index (PCI)Visual InspectionMaintenance ExperienceRehabilitation - Performance HistoryInitial Cost Dictates

  5. What about the pavement condition?

  6. Pre-maintenance; What about Patching?

  7. Pre-maintenance; What about Crack Sealing?

  8. Pavement Preservation – Scrub Seal Application

  9. Pavement Preservation - Slurry Seal Application

  10. Pavement Preservation - Micro Surface Application

  11. Pavement Preservation - Chip Seal Application

  12. Pavement Preservation - Hot Mix - Thin O/L Application

  13. Pavement Preservation - Multi-layered System Application

  14. 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!

  15. Partnering ConceptsCost Issues/ConsiderationsLets Try to Reduce Initial Cost!

  16. a) Inter-Agency Agreementsb) Concurrent Biddingc) Tag-on Contracts d) Renewable Contractse) JOC’sf) Specificationsg) Early Biddingh) Project Schedulingi) Construction Criteriaj) Materials Indexing

  17. Inter-Agency AgreementsIs this option possible?What are the liability issues for the lead agency?

  18. Concurrent Bidding PracticeAsphalt-Rubber Chip Seal Cost Comparison Example:Individual Project Cost - $ 4.87 per s.y.* Total square yards = 68,800Partnering Project Cost - $ 4.23 per s.y.* Total square yards = 404,000

  19. Tag-on ContractCommunication -Tag-on Usage Unknown!* Lead Agency Price to all ParticipantsCommunication – Tag-on Usage Known!* Similar Pricing as Concurrent Bidding

  20. Renewable ContractsandJOC’s

  21. Specifications – Consistency!Early Bidding - Contractors are Hungary!Project Scheduling - Start and Cutoff Dates?Construction Criteria - Production Limitations! Materials Indexing - Equality at Bid Time!

  22. 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?

  23. 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?

  24. Discussion!
