In Bolivia, A Law Mandates Concrete Pavements

A law passed in Bolivia on July 24th mandating the use of concrete pavements.  “A similar story happened in Paraguay, and for a while in Ecuador,” says Dr. Ing. Erwin Kohler of 3ipe. an international airport and road pavement engineering firm located in Las Condes. Santiago (Chile). 

The law provides for the use of portland and/or pozzolanic cement for the implementation of road infrastructure that are part of the Nation’s Primary Road Network. 

Dr. Kohler, a member of the ISCP Board of Directors, provided a translation of the law, noting he does not favor laws mandating pavement type, but offered the document for information purposes.  Click here to see the translated version.

NPCA Offers Jointed Precast Tech Manual

The National Precast Concrete Association (NPCA) has posted its Manual for Jointed Precast Concrete Pavement (3rd ed.). 

This comprehensive technical manual describes jointed precast concrete pavement systems in detail and presents a step-by-step guide that can be used by contractors, agencies/owners,  system designers, precast concrete manufacturers, contractors and inspectors. 

The manual includes dozens of technical illustrations, charts and photographs and is available as a complete PDF or as chapter-by-chapter PDFs, all on NPCA’s website.

Published by NPCA in conjunction with the NPCA Precast Concrete Paving Slabs Product Committee, the manual was written by Peter Smith, P.E. The Fort Miller Group*, and Mark B. Snyder, Ph.D., P.E., Pavement Engineering and Research Consultants, LLC*.

Kansas Seminar Covers Concrete Essentials

The 21st Annual Concrete Pavement Parking Lot & Flatwork Seminar held earlier this month covered some important and timely technical and business issues. Co-sponsored by the Missouri/Kansas Chapter and The Concrete Promotional Group of Kansas City, the seminar included two project overviews, a concrete paving “crash course,” ADA compliance considerations, and several technical presentations.

Moderated by Doug Burns of Ash Grove Cement, the event included technical presentations on concrete pavement jointing by Todd LaTorella of the Missouri/Chapter, as well as PavementDesigner.org design runs by Eric Ferrebee of ACPA National.

Ferrebee’s presentation is one of the latest in ACPA’s ongoing efforts to provide hands-on training and instruction. To date, he has provided this training to more than 2,000 industry and agency personnel.

 

 

PavementDesigner.Org Goes Live

PavementDesigner.org was officially launched earlier this month. ACPA Chairman Chuck Niederriter and ACPA President and CEO Jerry Voigt announced the official launch during ACPA’s annual reception at TRB on January 8. A formal media blitz was also launched on January 8, and press releases and social media postings followed throughout the week.

The TRB launch and media work represented just a few of the publicity, outreach, and educational initiatives planned for the year.

PavementDesigner.org is the the result of collaborative effort [1] for city, county, and consultant engineers, academia, or anyone involved in design of roadway, industrial, and parking area pavements.

Vision 2040 Takes Aim at Future Challenges, Solutions

Vision 2040 blue ribbon panel* holds first meeting to set a course for the next two decades.

What will concrete pavements and things related to paving and surface transportation infrastructure look like in 20 years?

That was the overarching question ACPA’s Vision 2040 “blue ribbon panel” considered when they met in late September, just after the close of the National Concrete Consortium meeting in Minneapolis. 

As reported previously, ACPA staff brought together a blue-ribbon panel of experts representing FHWA, State Departments of Transportation, Transportation Research Board, Contractors, Materials Suppliers, Consulting Engineers, Academia, and Equipment manufacturers to discuss a wide range of topics aligned with concrete design, construction, materials and equipment, and use-phase considerations. At times, the group focused on futuristic topics, while at other times, they discussed current and emerging trends, future possibilities, and a wide range of diverse solutions to meet the evolving needs over the next 20 years.

Gary Fick, Trinity Construction Management Services, Inc., an ACPA member, facilitated the discussion.  

Vision 2040 was modeled after a similar visioning session that took place 20 years ago.  The previous initiative, which took place in 1997, provided a Blueprint for Portland Cement Concrete Pavement Research Technology and Innovation.  That blueprint was subsequently expanded upon and translated into an Action Plan called “Creating a New Generation of Pavements” that provided a comprehensive research program to implement the goals contained in the Blueprint.  Our industry estimates that 80-85% of the goals and outcomes identified in the Action Plan have either been accomplished or are under way

With the Vision 2040 effort, there were no preset goals, which enabled the group to have a far-reaching discussion about current and emerging trends that will impact pavements … and more.  The group discussed “disruptive forces,” unpredictable and unforeseeable developments that can make a profound and lasting effect on transportation and, in some cases, on society.  The group also discussed and considered more conventional trends and patterns, such as:  increasing truck traffic and heavier loads; autonomous vehicles; e-commerce/distribution of goods; dedicated freight network; climate change; and the possibility of new ownership models, Fick reported. 

As part of the visioning effort the group also met in breakout sessions to discuss specific concrete pavement design, construction, materials, and use-phase issues, all with an eye on emerging trends and the challenges and opportunities that may arise over the next two decades. From those discussions, dozens of concepts and ideas emerged.  A few examples included self-healing pavements, pavements that perform multiple functions, equipment and material advancements, and process improvements.

ACPA staff, working with Fick, is now organizing these concepts and themes. The next steps will be for the Vision 2040 group to further discuss needs and opportunities and organize them into a plan to pursue in the years ahead.
