1 Back to the Future Revisiting the Next Generation of Pavements Initiative Iowa Concrete Paving Association Annual Workshop February 3, 2017 Gerald F Voigt, PE President & CEO American Concrete Pavement Association

2 The Things We Accomplish Today are Only Possible Because of the Achievements of Those Who Came Before Us

4 Eddyville Cemetery Rd Built 1912

5 100 Years Ago The Federal Highway Act was passed into law (1916). Highway network was in its infancy. Less than 3,000 miles paved concrete roads.

6 60 Years Ago The Interstate Highway System was started Dwight Eisenhower's vision $25 Billion for construction of 41,000 miles Created trust fund and introduced fuel taxes. Some concrete pavements built in that era have outlasted the funding mechanism!

7 60 Years Ago The commerciallymanufactured slipform paver took off born here in Iowa. Brought productivity from 1000 ft/day to 5000 ft/day. Single biggest impact in history of our industry. But Just one among a rich history of innovations!

8 A Rich History of Industry Innovations Slipform Paving Concrete Shoulders 1970 Econocrete (Lean Concrete) Created CPR 1980 Cross-Stitching Repair Method Invented Fast Track Paving Ultra-Thin Whitetopping Created Next Generation Surface Invented (w/igga) Line Lasers for Non-Contact Profiling Optimized Gradations Central Mix Plants Curing Compounds Reconstruction w/ Recycled Aggregates in Mix 1990 Dowel Insertion Side-by-Side Design Software Intersection Joint Layout Method First Webinars for Industry WikiPave Solutions Created or Fostered by ACPA

9 A Generation Ago Industry established a vision back in 1996! ACPA brought a group together to envision where the industry should head. Involved 25 experts from industry and public sector. We called it a blueprint (lol)

10 Was Anybody You May Know Involved? Don Beuerlein, Koss Construction Larry Scofield, AZ DOT (now IGGA/ACPA) Mike Darter, ERES (now ARA) Gordon Smith, ICPA Steve Tritsch, MO-KS ACPA (now CP Tech) Matt Ross, Ash Grove Cement (now CTS Cement) Snoop Dog

11 The Blueprint Suggested a Process for Innovation Test, Evaluate & Refine Ask Challenging Questions Implement Solutions PROCESS FOR INNOVATION Identify Needs Develop Solutions

12 How We Should Look at the Blueprint Today An important milestone in our history! A successful plan that: Made our product better! Answered agency challenges! A celebration of our industry s innovativeness! A catalyst for the current CP Road Map.

13 How Did We Do? 66 Projects Identified Under Five Goals Significantly Advanced More than 80% of these areas! Targeted Tech transfer Construction Design & Materials Maintenance & Rehab Specifications Significantly Advanced Some Work Done No Progress Made

14 What Kinds of Tech Transfer Did We Envision? Best Practices Manuals. Expert Systems. Design Software. Databases of Projects for Performance History. When We Set Out the Vision How old was the Internet?

15 What Types of Tech Transfer Did We Accomplish?

16 What Types of Tech Transfer Did We Accomplish? Aggregate Handling for Quality Concrete Pavement Construction 3-hour Course (FREE) Best Practices for Constructing Smooth Concrete Pavements 5-hour Training (FREE) Online Training

17 What Types of Tech Transfer Did We Accomplish? ACPA WikiPave

18 What Types of Tech Transfer Did We Accomplish? Web Apps

19 What Design Needs Did We Envision/Accomplish? Refined Concrete Overlay Design Mechanistic Design Calibration & Implementation Design Vision Optimum Joint Design for Extended Life Pavement Thin-Slab Concrete Pavement Design Optimized Dowel Bar Design

20 What Materials Needs Did We Envision/Accomplish? Influence of Coarse Agg. on Joint Design Value of Fibers in Concrete Pavements Use of RAP as an Aggregate Material Vision Tests to Identify Material Incompatibilities in Mixtures Durability of Pavement w/ Optimized Mixtures

21 What Construction Ideas Did We Envision/Accomplish? Two-Course Construction to Reduce Cost Measure Smoothness Behind the Paver Non-Destructive Measure for Pavement Thickness Construction Vision Curing and Texturing Requirements Pre-cast Paving for Rapid Repair

22 Anything Envisioned That is Still in Progress? Tolerable Limits for Dowel Bar Alignment Studies done/needed Guide specs developing Test Procedure to Determine Air Content Immediately Before and After Concrete Placement Super air meter PEM MIT-Scan Device Super Air Meter

23 Were There Any Half-Crazy Ideas? Registry System for all new projects Determine the Common Elements of Material Properties of Pavement with Extended Life One-pass reconstruction Slipform auto-pilot system

24 Autopilot System? Auger or Plow Uniformity Vibration Rheology Speed

25 What Really Made the Blueprint Successful? Test, Evaluate & Refine Ask Challenging Questions Implement Solutions PROCESS FOR INNOVATION Identify Needs Develop Solutions

26 Implementation is Not an Accident! Requires intentional efforts. Requires focus. Requires taking on risks. Requires collaboration: Industry (contractor) Agency (engineer) Requires money!

27 How Has Industry Helped Implementation Led lobbying efforts for technology implementation legislation in highway bills. Most recently in FAST Act: AID-PT Accelerated Implementation and Deployment of Pavement Technologies. Collaboration between ACPA and NAPA. $12M/year for implementation of technology. Good for our industry.

28 People Make it Happen thru Partnerships ACPA National International Grooving & Grinding Assn. Agencies ACPA Chapters & State Assn. CP Tech Center

29 A Look Ahead SO NOW WHAT?

30 It s Time to Do It Again! ACPA will bring another group together this year. Apply the process for innovation. Look at refining and expanding new vision based upon the advancements that have occurred! Envision where promising new technology can take us!!!

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