Indiana Chapter Workshop Hits the Mark

About 180 highway engineers, inspectors, contractors, and suppliers gathered yesterday (Feb. 18) for the 2020 Indiana Concrete Pavement Workshop and annual awards presentation.

Speakers from the Indiana DOT (INDOT), FHWA, and the concrete paving industry provided insights on the Indiana Transportation Team initiative toward better process and communication.

A technical session addressed optimized concrete mixes, innovation in testing, pavement restoration, and the use of thin concrete overlays as a preservation treatment for appropriate segments of state and local road networks. Awards recognized work at Grissom Air Reserve Base, and projects on I-74, I-70, I-865, Ryan Rd. in Allen Co., Eastside Parkway in Gas City, Kessler Blvd., and 38th St. in Indianapolis, US 40 in Richmond, and SR 37 in Lawrence Co. were presented as well.

Technical and business presentations included:

  • INDOT Perspectives – Progress and the Indiana Transportation Team: Roland Fegan Deputy Commissioner INDOT.
  • FHWA Perspectives and Initiatives: Mayela Sosa, Indiana Administrator, Federal Highway Administration.
  • INDOT Partial Depth Repair Progress: Mike Nelson, INDOT.
  • Wisconsin’s Effort to Implement Optimized Concrete Mixes: Kevin McMullen, Wisconsin Concrete Pavement Association.
  • Aggregate Optimization Considerations at  INDOT: Matt Beeson, INDOT & Devin O’Dell, Milestone Contractors.
  • How to Produce Better PCCP with Optimized Aggregates; Chris Tull, CRT Concrete Consulting.
  • The Patch: Non-destructive Testing with Piezoelectric Sensors: Dr. Luna Lu, Purdue University.
  • Why You Should Pay Attention: Changes to Achieve Better Performing PCCP–Mike Byers, Indiana Chapter-ACPA.
  • Report on Thin Concrete Overlays: Looking Forward: Indiana Chapter-ACPA.

Purdue Team Using Piezoelectric Tech for Concrete Maturity Testing

A team of Purdue University researchers, working with the Indiana DOT, is collecting data to determine optimal concrete maturity using an experimental test method on select highway paving and patching projects.

The goal is to determine the best times to open projects to traffic.  The team of researchers is led by Dr. Na (Luna) Lu, an associate professor at Purdue’s Lyles School of Civil Engineering and an Indiana Chapter-ACPA Scholar in Concrete Pavement and Materials Science. 

The team is collecting data through sensors the group designed to track concrete strength development in real time through measurements of hydration, stiffness, compressive strength and other concrete properties. The work is being done on projects being constructed by two ACPA members, E&B Paving and Milestone Contractors, L.P.

After testing, INDOT plans to adopt the sensors, allowing them to remain permanently in highway pavements with the aim of keeping contractors informed of concrete distresses.

The test method involves embedding a sensor patch to the concrete surface and connecting it with wires to a measurement system. Using piezoelectric effect, electric polarization resulting from mechanical stress, the sensors provides accurate measurements of many concrete properties at once.  Dr.  Lu and her team will be presenting a detailed report on the testing during NC2 next week.  (See the related story, “ACPA Previews NC2.”)

AASHTO Names Hendrickson as Deputy Director

The American Association of State Highway and Transportation Officials (AASHTO) has named Brandye Hendrickson, currently the Federal Highway Administration’s (FHWA’s) Deputy Administrator, as its new deputy director.

Appointed to her current FHWA role in July 2017, Hendrickson served as the agency’s acting administrator for two years until Nicole R. Nason officially became the FHWA Administrator in May.  

“I am thrilled that someone with Brandye’s experience and leadership ability is joining the AASHTO team,” said Jim Tymon, AASHTO’s Executive Director. “She has a deep knowledge of the challenges facing surface transportation and that knowledge is going to directly benefit AASHTO and our member departments of transportation.”

“I’m excited about continuing to serve the transportation community in this new role and joining such a great team at AASHTO,” Hendrickson said in a statement.

The AASHTO announcement follows a search that began in May. Before joining FHWA, Hendrickson served as commissioner of the Indiana Department of Transportation for two years and served as a member of AASHTO’s Board of Directors and Executive Committee until her FHWA appointment.

According to an AASHTO job posting, “The deputy director assists with managing the internal and external affairs of the organization, providing guidance and support to the association’s board of directors, as well as to its committee and council leadership.”  The deputy director also serves as a spokesperson and liaison between AASHTO and a variety of external agencies and organizations, including Congress, state legislatures, government agencies, the media, and other public groups, according to the posting.
