Preventative Maintenance or Corrective Maintenance or Both

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?
