ACPA presented its 2019 Marlin J. Knutson Award for Technical Achievement to Paul Jaworski, Product Manager, Minnich Manufacturing, Inc. The award is presented in recognition of Jaworski’s more than 40 years of expertise in concrete vibration and consolidation technology.
“With direct involvement and contribution to virtually all the significant inventions and technological advancements of concrete vibration technologies, you have earned the reputation of being an expert, thought leader and trusted advisor in the art and science of concrete consolidation,” says Gerald F. Voigt, ACPA President & CEO.
The Marlin J. Knutson Award for Technical Achievement is presented to an individual or group who has made significant contributions to advance the development and implementation of technical innovations and best practices in the design and construction of concrete pavements.
This award is named in honor of the second chief executive of the American Concrete Pavement Association. Marlin J. Knutson served in that role from 1985 to 1998, and during his tenure, was a staunch advocate for technical service and technology transfer. The Knutson Award for Technical Achievement has been presented since 1998.
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.

ACPA presented the 2019 Outstanding Pavement Promotion Award to Mike Byers, Executive Director, Indiana Chapter-ACPA.
This award recognizes Mike’s leadership in advocating for the use of concrete pavements and his work in improving the design, constructability, preservation and maintenance of Indiana’s roads and highways.
The award also recognized his collaboration with the Indiana DOT and Purdue University (including some 45 study advisory groups) that has made a positive and lasting impact on the many individuals he has mentored, guided and supported.
“By making concrete pavements and concrete promotion your life’s work, you have earned the respect of a grateful industry, which recognizes you as a soft-spoken, powerful leader, promoter and local expert,” says Gerald F. Voigt, ACPA President & CEO.
The ACPA Outstanding Pavement Promotion Award has been awarded selectively since 1998. It is presented to an individual or group who has made significant contributions through promotion efforts or programs to advance the awareness, specification, and/or placement of concrete pavements. The recipient must be an employee of an ACPA member company, ACPA national staff, or staff of a local chapter/state association affiliated with ACPA.
VDOT Receives Lifetime Pavement Recognition Award

ACPA presented its Lifetime Pavement Recognition Award to the Virginia Department of Transportation (VDOT) in recognition of a section of Virginia State Route 316. Accepting the award was Mike Davis, P.E., C.C.M., VDOT, Hampton Roads Deputy District Engineer for Construction and Engineering.
With only minimal maintenance, State Route 316 (Greenbush Road) has served the communities of Accomack County, Virginia, for about eight decades.
This exceptional pavement has far exceeded its original design life and exhibits the durability and performance for which concrete pavement specifiers strive.
“This highway is not only an important travel route for local communities but is an excellent example of the longevity that has become one of the greatest values and true hallmarks of concrete pavement,” says Gerald F. Voigt, P.E., ACPA President & CEO.
Awarded selectively since 1994, this special recognition is presented to the agency owner of an in-service concrete pavement that has demonstrated exceptional performance and service to its local community, state and users. (This recognition rotates annually among public market segments: highway, street and airports.)
Divided Highways (Urban) – Silver Award

Silver Award – I-440 from Arkansas River Bridge to 140 , Little Rock Ark.
Contractor: Koss Construction Company*
Owner: Arkansas Department of Transportation
Engineer: Bridgefarmer & Associates Engineering
Koss Construction Company had the challenge of reconstructing the concrete pavement on a very busy stretch of Interstate 440 on the east side of Little Rock, Ark.
Facing a tight schedule, tough access and high standards, the team needed to assemble quickly and intentionally to have a shot at a successful project. Using a majority of local subcontractors and suppliers, Koss hit the ground running as soon as temperatures allowed. They removed the rumble strips by milling and filling with a magnesium-phosphate based patching material. After the traffic was switched, it was time to remove the old pavement and make ready for new.
The Arkansas Department of Transportation placed a huge emphasis on the time of construction by bidding it with the A+C method. With a daily road user cost set by the owner at $35,000 per day, Koss bid to complete this project in just 294 calendar days. Every minute counted as the team began to remove and replace over 208,000 SY of pavement along 19 lane miles.
Many issues compounded the complexity of this project, but none more than requirement to match the inside lane profile to the existing 27 year-old concrete shoulder that the owner wanted to remain in place. By carefully planning the removal and reconstruction of some of the most off-profile shoulder segments, the constructed pavement lane was able to meet thickness and smoothness requirements.
The concrete mix used on this project was as close to a Performance Engineered Mix as allowed under current ArDOT specifications. The mix was designed to have a low paste volume with low permeability and good air characteristics. FHWA was on site during paving and verified the quality mix through a battery of PEM tests which included super air meter (SAM), Box Test, Surface Resistivity, Rapid Chloride Permeability and Calorimetry.
