I nfrastructure Management • Asset Management Approach • Innovative Contracting Methods • Innovative Construction Methods • Use of Innovative materials

Asset Management A systematic process to cost effectively maintain, upgrade and operate an organization’s infrastructure by inventorying assets (roads, bridges, utilities, equipment, facilities) and evaluating specific data (condition, value capacity) in order to make critical infrastructure decisions based on fact rather than assumption.

Transportation Asset Management Overview Goals and Objectives Inventory and Analysis of Options condition assessment and Tradeoffs Preservation, Operations, Policies Capacity Expansion Budgets Feedback Decision-Making & Expectations Resource Allocation Implementation Monitoring and Performance Measures

Transportation Asset Management RESOURCES Preservation Operations Capital Safety Other Improvement

Strategic Highway Research Program (SHRP 2) • Innovative construction methods • Innovative bridge designs for rapid renewal • Durable bridges for service life beyond 100 years

Renewal Program - Goals “GET IN, GET OUT, Rapid STAY OUT” Approaches The search for renewal tools and techniques that reduce preparation Successful and execution times, Renewal reduce disruptions to Minimal traffic, utilities, and Long-Lasting Disruption neighborhoods, and Facilities extend the time between renewal activities

Innovative Contracting Methods • Contracts with cost and time components (A+B) versus exclusively low bid contract • Performance contracting with specific performance requirements • Design-Build-Finance alternatives being investigated

“ABC” Accelerated Bridge Construction • Precast bridge elements • Building bridges and moving them into place • Scheduling to reduce customer delays

An Illustration of ABC (Accelerated Bridge Construction) Parkview Avenue over US-131

Demolition Took Place at Night with Maximum 5 Minute Freeway Closure Beam removal was done at night allowing for a maximum of 5 minute lane closures

All Bridge Components were Precast Concrete

This abutment segment took Abutment Placement 8 minutes to place

Placement of the Pier Caps

Prestressed I -Beams were Placed at Night

The Bridge Deck was Made of Precast Concrete Panels 48 deck panels were placed in four days

A Hot-Mix Asphalt Wearing Surface was Placed on the Deck Waterproof membrane and 1 ½ inch lift of hot mix asphalt (HMA) placed on top of the concrete deck panels

Parkview over US 131 After Before

Self-Propelled Modular Transporters • Used to move entire bridge spans into place • Reduces roadway closure time • Less impact to the traveling public

Bridge Preservation • Epoxy Overlays on bridge decks • Zinc-based primer paint systems for steel beams • Acrylic coatings for concrete elements

Durable Bridges for Service Life Beyond 100 Years • Innovative materials and designs • Protecting bridges with preventive maintenance

I nnovative Materials Designed for Maximum Durability • Non-corrosive materials – Carbon fiber reinforced composites – New alloys of stainless steel • Ultra-ductile, high-performance concrete

Column Wrapping with Fiber Reinforced Polymer sheets
