Speaker: Prof. Jorge Zornberg, P.E.

Jorge ZornbergThis training lecture will be offered once in English and once in Spanish. The specific focus of the lecture is on the use of geosynthetics as reinforcement elements in pavement systems. While geosynthetics can be used for multiple functions in pavement design, the scope of the training lecture is on reinforcement applications only. The specific contents of the training lecture will be tailored to address the needs of transportation agencies across the Americas. For example, there are significant differences in the geosynthetic type of choice for this applications in different regions. We plan to conduct two Training Lectures: Geosynthetic-Reinforced Pavements (in English) and Pavimentos Reforzados con Geosintéticos (en Español). The scope of the two training lectures will be the same for each language.

The instructor is fluent in English, Spanish, and Portuguese; hence, he will be able to facilitate discussions at the end of the session. He has conducted a number of professional short courses in the past with emphasis on geosynthetics, soil reinforcement, and pavement design. The training lecture course is expected to be highly attractive to design engineers in the various transportation agencies.

Course Level
The lecture is appropriate for all levels, from novice to expert. However, while a mixed audience of practitioners, manufacturers, and academics is expected, the overall presentation will aim to satisfy current needs from the practitioner point of view.

Learning Objectives

  1. Provide technical basis for the design of geosynthetic reinforcements in pavement design
  2. Apply important technical concepts into design

About the Instructor
Dr. Zornberg, P.E., is Professor and William J. Murray, Jr. Fellow at the University of Texas at Austin. He earned his B.S. from the National University of Cordoba (Argentina), his M.S. from the PUC of Rio de Janeiro (Brazil), and his Ph.D. from the University of California at Berkeley. He has over 25 years’ experience both in research and practice in geotechnical, geosynthetics, transportation, and geoenvironmental engineering. Prof. Zornberg participated in the analysis, design and forensic evaluation of retaining walls, reinforced soil structures, transportation systems as well as mining and waste containment facilities. He has served as expert witness in cases involving the collapse of earth retaining structures, failure of barrier systems, and failure of pavements and structures on expansive clays. Prof. Zornberg conducts research on soil reinforcement,geosynthetics, earth retaining structures, pavements, waste containment and mining facilities, unsaturated soils, and numerical and physical (centrifuge) modeling of geotechnical systems. He teaches graduate courses at the University of Texas on Earth Retaining Structures and on Geoenvironmental Engineering. Prof. Zornberg served as president of the International Geosynthetics Society (IGS) during the period 2010-14. He has authored over 350 technical publications, edited a number of publications and book chapters, and been awarded three patents. Prof. Zornberg has been invited to deliver keynote lectures in numerous events around the world. He received many prestigious awards, including ASCE’s Croes medal and Collingwood Prize, IGS’ Award and Young Member Award, as well as the Presidential Early Career Award for Scientists and Engineers (PECASE) awarded by President George W. Bush to Prof. Zornberg in 2002.

Speaker: Ryan Berg

Geosynthetics have been used for over 50 years to construct roadway embankments and to enhance pavement performance. They provide sustainable solutions and cost savings, provided they are appropriately designed, properly specified, and correctly installed. GeoTechTools is a web-based knowledge system that provides a synthesis of critically important information about gesosynthetics, as well as other ground improvement and geoconstruction solutions. The system makes the information readily accessible to the user. The objectives of this workshop are to introduce GeoTechTools as a means of identifying methods for improving roadway performance using geosynthetics in various applications, locating current guidelines for design and material specifications, and recognizing improvements in design and materials to advance the application of geosynthetics. Applications addressed in the workshop include:

  • Pavement subgrade stabilization
  • Embankment support over soft soils
  • Drainage (e.g., underdrains, interceptor drains and structural drains)
  • Base reinforcement beneath flexible pavements
  • Roadway widening, including compaction aids for embankment construction
  • Reinforced load transfer platforms (LTP) supported on piles for embankment support
  • Reinforced soil for construction of overly steepened side slopes

Learning Outcomes
Upon completion of this workshop, participants will be able to:

  • Discuss components of GeoTechTools System
  • List 12 technologies on GeoTechTools that use geosynthetics
  • List four application areas covered by system
  • Describe the technology selection process
  • List two primary components of GeoTechTools system
  • Discuss types of technology tools contained on GeoTechTools system
  • Describe the technology selection assistance system
  • Recall GeoTechTools features that can be used address constraints and mitigate risks
  • Recall how GeoTechTools can be used in the construction phase to address construction problems

Moderator: Mike Adams

Mike AdamsThe typical order of progression in engineering is that theory precedes practice. However, this order of evolution is typically reversed in geotechnical engineering where the development of theory is based on the observed behavior of in-service structures, often requiring refinements to current design or the introduction of new methodologies to explain the empirical observations. This creates a natural lag between the state of practice and the state of the art. Designers rely on current guidance and specifications and are usually reluctant to step outside existing boundaries. The advancement of concepts necessary to implement more cost-effective designs are often delayed, ignored, or criticized. The adaptation of current guidance to implement these concepts can be challenging. This panel discussion will address the pertinent design assumptions and observations of reinforced-soil systems, how those assumptions differ from standard MSE design and construction practices, the pros and cons of introducing different theories to the design of reinforced soil, and methods to implement change effectively. The discussion is not about particular design methods; it’s about the observed realities of reinforced-soil technology implementation, disruptive innovation, and solutions that can create a positive environment within the industry to further advance reinforced soil technologies.
