Reflections… And a Look Ahead From 2016

Wisconsin Concrete Pavement AssociationFebruary 10, 2016

Gerald F Voigt, PEPresident & CEO

American Concrete Pavement Association

Some Perspective to Start 2016…

125th Anniversary of First Concrete Pavement in U.S.Built by George Bartholomew – first U.S. concrete paving contractorStill in Service!

Some Perspective to Start 2016…

Bellefontaine, Ohio 8-ft.-wide strip.Called “artificial stone”Two course construction

Hard aggregate on top so horseshoes wouldn’t wear pavement.Grooved in 4” squares so horses would not slip

Some Perspective to Start 2016…

Bartholomew posted $5000 bond for 5 year guaranteeImmediate success!Local business owners petitioned to have the entire block around town square paved in 1893.

By 1916 there Were More Than 2,500 Miles of Concrete Roads

Seedling MileOne lane, 9 feet wideIndustry built these in the hope that once motorists tried it, they would lobby for more miles of paved roads

Some Perspective to Start 2016…

In 1916 the Federal Highway Act was passed into lawLobbied for by bicyclists organization “Wheelman of America”By 1916, there were more than 2,500 miles paved concrete roads.

By 1916 There Were 10,000 Autos in the U.S.

Today… Over 256 Million!

Some Perspective to Start 2016…

60 years ago the Interstate Highway System was startedDwight Eisenhower's vision$25 Billion for construction of 41,000 milesCreated trust fund and introduced fuel taxes.Some concrete pavements built in that era are still in service, but funding system broken!

First Commercialized Slipform Paver…

Paved 28 miles in 1955.Other manufacturers had units in use by 1956.

Improved productivity from 1000 ft/day to 5000 ft/day

A Generation Ago…

We established a vision 20 years ago.ACPA brought a group together to envision where the industry should head.We called it “Creating a New Generation of Pavements”We called it a “blueprint”

Who Was Involved?

The Blueprint Suggested a Process for Innovation

Ask Challenging Questions

Identify Needs

Develop Solutions

Refine

PROCESS FORINNOVATION

How Should We Look at the Blueprint Today…

Celebration of our innovation over the years!An important vision of where we needed to head as an industry!A successful plan that made our product better and answered agency challenges!

Goals Identified in the Blueprint

Goal 1 – Develop “Current Best Practices”Goal 2 – Reduce Initial CostGoal 3 – Reduce User Costs Associated with Concrete Pavement ConstructionGoal 4 – Develop Cost – Competitive Concrete Options for All Paving ApplicationsGoal 5 – Increase the Certainty that Concrete Pavement will Achieve Design Expectations

How Did We Do?

66 Projects Identified Under the Five GoalsSignificantly Advanced More than 83% of these areas!Targeted Construction Design & Materials Maintenance & Rehab Specifications

Significantly AdvancedSome Work DoneNo Progress Made

What Kinds of Tech Transfer Did We Envision?

We Must be Doing Something Right!

WikiPave has Won a “Top Rollout” Award for 2015!In recognition of the “risk and reward” of introducing new products to highway professionals.

What Types of Tech Transfer Did We Accomplish?

Aggregate Handling for Quality Concrete Pavement Construction

3-hour Course (FREE)

Best Practices for ConstructingSmooth Concrete Pavements

5-hour Training (FREE)

Sponsored by Federal Highway Administration

What Design Needs Did We Envision/Accomplish?

Optimized Dowel Bar DesignsRefined Concrete Overlay DesignMechanistic Design – Review, Calibration & ImplementationOptimum Joint Design for Extended Life PavementsThin-Slab Concrete Pavements

What Materials Needs Did We Envision/Accomplish?

PROCESS FORINNOVATION

Implementation is Not an Accident!

Requires intentional effortsRequires focus Requires taking on risksRequires moneyRequires collaboration

How ACPA Has Helped…

Led lobbying effort for technology implementation legislation:

AID-PT – Accelerated Implementation and Deployment of Pavement Technologies.Successful in getting provision in MAP-21 and Fast Act.Collaboration between ACPA and NAPA.$12M/year for implementation of technology.CP Tech Center integral to delivery!Good news for our industry.

SO NOW WHAT…?A Look Ahead

It’s Time to Coalesce Around a New Vision

ACPA will bring another group together this year to brainstormApply the process for innovationLook at refining and expanding upon the advancements that have occurred!20 years is not that long of a time span!!!

The Next Vision Will Be Driven by Current Agency Needs…

Long Lasting Smooth Cost

Effective Rapid Sustainable

And… Our solutions must remain competitive!

Technology That’s Sure to be Part of the Vision!

Internal Curing• Employs high-absorption

fine aggregates to introduce water for thorough cement hydration.

• Improves mix uniformity and avoid curling/warping.

Super Air Meter• Better characterizes air void

system.• Helps achieve durable

concrete and lowers the susceptibility to scaling, cracking or other damage.

Performance Engineered Mixtures (PEM)• Optimizes paste and

aggregate components.• Mixes specifically for

paving.• Changes spec goal from

strength to durability

Technology That’s Sure to be Part of the Vision!

Real-Time Smoothness Measurement• Important paving

crew feedback for ultimate quality.

• Ties crew actions and machine operation to results.

Long-Life Dowels & Rebar• Ensures

embedded bars last as long as the concrete.

• Reduces corrosion-related problems.

Maturity Testing• Non-destructive

test uses time-temperature relationship of concrete to estimate strength.

• Facilitates opening and traffic management.

Mechanistic Pavement Design• Allows for

optimization of thickness.

• Addresses common over-design of concrete pavements.

Technology That’s Sure to be Part of the Vision!

Stringless Paving• A new way of guiding

pavers.• Useful when lateral

clearances are tight.• Growing in usage.• Instruments will evolve

Zero-Clearance Paving• Enables concrete

paving without extra room needed for paving machine.

• Helps with traffic management.

Smart Curing • Smart technology uses

on site information to determine curing condition/need.

• Addresses durability, curl/warp and plastic cracking.

It’ll Be Fun to See Where We Go From Here!
