Office of Infrastructure Future of the US Federal Highway Program American Concrete Pavement Association Annual Meeting San Diego, CA Thursday, November 30, 2017 Thomas D. Everett Associate Administrator FHWA Office of Infrastructure
Presentation Outline Status of Proposed Infrastructure Bill FHWA Program Direction Performance Based Approach Deployment through Technology Transfer 2
Status of the Proposed Infrastructure Bill $200 billion in infrastructure funding to leverage $1 trillion investment White House outreach FY 2018 fact sheet key principles Make Targeted Federal Investments Encourage Self-Help Align Infrastructure Investment with Entities Best Suited to Provide Sustained and Efficient Investment Leverage the Private Sector 3
Status of the Proposed Infrastructure Bill WHAT LIES AHEAD Secretary Chao recently stated that an infrastructure funding proposal will not come out until after Congress has addressed tax reform. The next step would be for the Administration, including USDOT, to work with the Hill on getting an infrastructure bill passed. WHAT WE ARE DOING AT FHWA We are looking for ways we can improve the project delivery process even without a statutory change. 4
Performance Based Approach MAP-21 laid out a framework for a more performance driven approach to the Federal Highway Program FAST Act continued the principles We see the transition through: Transportation Performance Management Risk Based Asset Management Plans Designing Concrete Pavements to Meet Performance Goals 5
Transportation Performance Management A strategic approach that uses system information to make investment and policy decisions to achieve transportation system performance goals. 6
7 Pavement Measures 23 CFR 490.307 490.307 Performance Measures Pavement Condition Measures Interstate System Non-Interstate NHS Percentage of pavements of the Interstate System in Good condition Percentage of pavements of the non-interstate NHS in Good condition Percentage of pavements of the Interstate System in Poor condition Percentage of pavements of the non-interstate NHS in Poor condition
Risk-based Asset Management Plan Plan Contents: Pavement and bridge inventory and conditions on the NHS. Objectives and measures. Performance gap identification. Life-cycle planning Risk management analysis. Financial plan. Investment strategies. 8
9 Optimizing Design through Implementation of Pavement-ME Planned Activities Pooled fund support Pavement ME Design Users Group Web-based clearing house for ME information Similar to ASR Reference Center Development of standard design tables (Design Catalog) Best-practice guidelines for different design conditions Resource for design checks Development of pavement-design, best-practices guidance Pavement preservation - designing for long-life pavements Improved foundation design
10 Pavement ME Implementation Map - PCC
11 Implementation of Performance Engineered Concrete Mixtures (PEM) Background Focal point for moving concrete specifications and practices in a performance direction Expert Task Group (ETG) included states, FHWA, academia, ACPA, others (initiated 2013) Provisional practice PP 84-17 published by AASHTO Incorporates new tests that correlate to performance Requires Quality Control activities
12 Implementation of Performance Engineered Concrete Mixtures (PEM) Planned Activities Continue to refine test methods and equipment (Mobile Concrete Trailer participating) Develop QA and QC tools (Plan templates, control charts, videos on new tests, etc.) for states and industry ACI Concrete Performance Specification Workshop piloted and refined
PEM POOLED FUND PARTICIPANTS TPF-5(368) 13 States + FHWA & Industry (October 2017)
Industry Participants in the Pooled Fund American Concrete Paving Association State Concrete Paving Chapters/Associations Portland Cement Association Ready Mix Concrete Foundation Slag Cement Association American Coal Ash Association Others (admixture, aggregate, etc. are currently considering)
FHWA Mobile Concrete Trailer Visits State construction projects Promotes new technologies Supports Performance Engineered Mixture Design (AASHTO PP 84-17) Advances new test procedures Loans test equipment Trains States and industry on new tests Quality in the Concrete Paving Process Workshop 19 Agencies have made changes since 2010 due to the MCT 15
