FHWA Receives ACPA Sustainable Practices Award

ACPA presented its 2019 Sustainable Practices Award to the Federal Highway Administration.

The award was presented in recognition of leadership in creating a framework for sustainable design and construction practices that consider societal, environmental and economic factors (the triple bottom line).  Accepting the award for the FHWA was Gina Ahlstrom, FHWA Pavement Materials Team Leader.

Since 2011, the FHWA-led Sustainable Pavements Technical Working Group (SPTWG) has been a positive and productive forum for the public and private sectors. The SPTWG has earned high marks for its open exchanges among stakeholders.

FHWA has fostered increased awareness of use-phase impacts, which are now considered essential elements of sustainability and life-cycle analysis. The award has been presented selectively since 2010 to organizations or teams (owner and contractor) that demonstrate leadership by implementing sustainable design and construction practices that consider societal, environmental and economic factors.

FHWA Offers Workforce Insights in Partnership Meeting

A Highway Construction Workforce Partnership (HCWP) partners’ meeting provided insights into the solutions to federal programs aimed at addressing workforce issues, including shortages and developmental programs.  

The meeting began with opening remarks by Tony Furst, FHWA Chief Innovation Officer, and Nancy Rooney, U.S. Department of Labor Deputy Assistant Secretary. Leif Wathne of ACPA and Jay Hansen of NAPA both had an opportunity to share comments with the group.

The meeting covered a variety of topics, including outreach/marketing, FHWA HCWP grants, and a notice of proposed rulemaking for an apprenticeship program. Participants also received a summary of HWCP activity in various states and cities.

The meeting was held on November 4 and was  hosted by the FHWA’s Center for Transportation Workforce Development and took place at the U.S. Department of Labor (DOL) headquarters in Washington, DC. In addition to the key agencies, other partners include AGC, ARTBA, AASHTO, the DOL’s Employment and Training Administration, and NAPA.

Publication Explains Concrete Test Method

The FHWA Mobile Concrete Technology Center (MCTC) is offering a one-page tech transfer document that provides some observations on a simple, inexpensive field testing concrete & cementitious material hydration. Hydration, of course, creates exothermic chemical reactions, which can be monitored by measuring the total heat generated over time.

“Monitoring Concrete Consistency using Semi-Adiabatic Calorimetry” descibes a test method that can monitor batch-to-batch consistency of concrete mixtures.  The test works by casting a standard concrete cylinder, then placing it in the calorimenter, recording the time-temperature curve (or heat signature), then comparing the curves of other samples from the same mixture.    

Calorimeters are described as effective tools during mix design to determine potential material incompatibility or optimal dosages/sequence of addition of admixtures. They can be used to determine setting times and saw cut times in lieu of physical testing.  Semi-adiabatic calorimeters can also be used as a quality control tool to monitor variations in the sources, quantities, and chemistry of portland cement, supplementary cementitious materials, and chemical admixtures during concrete production.  Click here to download a copy of the document.

ACPA Participates in FHWA Long-Term R&D Discussions

ACPA participated in an Expert Task Group for the FHWA Long-Term Infrastructure R&D program.  Leif Wathne participated in the long-term pavement performance (LTPP) group. A second group focuses on long-term bridge performance (LTBP). 

Leif Wathne participated in the meeting, which covered a range of topics related to long-term pavement research. Among the key questions the pavement performance group

  • How has LTPP data fundamentally improved understanding of pavement performance?
  • What are the critical, high-priority knowledge gaps?
  • What are the top 3 analysis projects to submit to NCHRP?
  • What is the ETG’s top priority to be funded by LTPP?

The meeting was held last week at the National Academies of Sciences in Washington, DC.

FHWA Offers Pavement Restoration Checklists

In the resource spotlight this week is the National Concrete Pavement Technology Center’s (CP Tech Center’s) series of updated and new pavement preservation  checklist.

Originally developed by the Federal Highway Administration (FHWA) in 2002, the preservation checklists provide excellent information on innovative pavement preservation techniques. Designed to guide state and local highway preservation/maintenance and inspection staff, the checklists provide useful information to contractors and others with an interest in concrete pavement preservation, repair, and restoration. 

Checklist topics include the following: 

• Joint and Crack Sealing • Full-Depth Repair
• Diamond Grinding • Cross-Stitching
• Dowel-Bar Retrofit • Longitudinal Diamond Grooving
• Partial-Depth Repair  

 

The complete list of 2019 and 2002 checklists may be found on FHWA’s pavement preservation resource website. The CP Tech Center also includes a link to the resources on its curated online library of pavement preservation resources.
