Update from the CEN Technical Committee CEN/TC 189 Geosynthetics

Introduction

CEN/TC 189 on Geosynthetics was established in 1989 in the light of the newly introduced Construction Products Directive (CPD). The aim of the Technical Committee is to develop terminology, testing and specification standards for a variety of construction products grouped together under the name ‘Geosynthetics’. In 1996 the European com-mission issued a mandate for developing European specifications standards, which was revised in 2007 due to the extending number of European countries. When the CPD was replaced by the CPR (Construction Products Regula-tion), the specification standards had to be revised to fulfil the new regulation.

Structure of CEN/TC 189

TC Management

The secretariat of CEN/TC 189 has been with the NBN (Belgium) since its establishment in 1989. Daniele Cazzuffi (Italy) started his first term as chairman in 2012, and has recently been confirmed as chairman for another three years starting in 2018. Karin Eufinger (Belgium) started as TC secretary in 2015.

Daniele Cazzuffi (Chairman CEN/TC 189) & Karin Eufinger (Secretary CEN/TC 189)

Working Groups

CEN/TC 189 has 6 working groups, which were all established during the founding meeting of the TC.

Working Group 1: Geotextiles and Geotextile-Related Poducts – General and Specific Requirements
Working Group 2: Terminology, Identification, Sampling and Classification
Working Group 3: Mechanical Testing
Working Group 4: Hydraulic Testing
Working Group 5: Durability
Working Group 6: Geosynthetic Barriers – General and Specific Requirements

Working groups 1 and 6 develop specification standards for Geotextiles and geosynthetic barriers. They are sup-ported by working groups 2 through 5, which develop the general standards for terminology (including identification, sampling and classification), testing and evaluation of durability.

Participation and Meetings

All CEN members may register participants to the technical committee, but the more active countries include Austria, Belgium, Czeck Republic, Denmark, Estonia, Finland, France, Germany, Greece, Italy, Latvia, Luxembourg, the Netherlands, Norway, Poland, Portugal, Romania, Slovak Republic, Spain, Sweden, Switzerland, Turkey, United Kingdom.

Also the European associations EDANA, ESWA and EuBa participate as observers.

Plenary meetings of CEN TC 189 take place once a year: the last meetings were in Istanbul in 2015, in Tallinn in 2016 and in Geneva in 2017, while the next meetings will be in Berlin in June 2018.

Cooperation with other Standardization Technical Bodies

CEN/TC 189 works closely together with ISO/TC 221 on Geosynthetics to ensure that the work program is aligned to international developments.

CEN/TC 189 also follows up the work program of other CEN technical committees on the one hand to be informed about developments in related technical areas and on the other hand to inform these technical areas of the develop-ments in CEN/TC 189. In order to facilitate this process, official liaisons to the following committees have been established:

  • CEN/TC 227 Road materials
  • CEN/TC 250/SC7 Eurocode 7 – Geotechnical design
  • CEN/TC 254 Flexible sheets for waterproofing
  • CEN/TC 288 Execution of special geotechnical works
  • CEN/TC 350 Sustainability of construction works
  • CEN/TC 351 Construction Products – Assessment of release of dangerous substances
  • CEN/TC 396 Earthworks

Committees CEN/TC 350 and CEN/TC 351 have a special role in this context. They develop horizontal standards for construction products, which then have to be used as basis for developing product specific standards for evaluating the sustainability of construction works and the assessment of the release of dangerous substances, respectively.

Work Program

The work of CEN/TC 189 is developed in the different working groups.

Working Group 1: Geotextiles and Geotextile-Related Products – General and Specific Requirements

Convenor CEN/TC 189 WG1: Philippe Delmas, France

Working group 1 develops specification standards for geotextiles and geotextile related products. Its core activities are related to the maintenance of the existing standards for CE marking and to develop new standards to ensure that novel materials or applications can be covered.

In March 2017 a series of revised standards was approved for citation in the official journal of the EU, providing not only a technical update but also an update to the new requirements and procedures under the CPR. This series of standards covers the following applications:

  • Drainage systems (EN 13252:2016)
  • Construction of reservoirs and dams (EN 13254:2016)
  • Construction of railways (EN 13250:2016)
  • Earthworks, foundations and retaining structures (EN 13251:2016)
  • Construction of tunnels and underground structures (EN 13256:2016)
  • Solid waste disposals (EN 13257:2016)
  • Liquid waste containment projects (EN 13265:2016)
  • Construction of roads and other trafficked areas (excluding railways and asphalt inclusion) (EN 13249:2016)
  • Construction of canals (EN 13255:2016)
  • Erosion control works (coastal protection, bank revetments) (EN 13253:2016)

The application standard for use in pavements and asphalt overlays (EN 15381:2008) is currently under revision, and it expected to be finalized in 2020.

Additionally, a new application standard is being developed for surface erosion control on slopes and banks (prEN 17097). This standard is currently being prepared for CEN Formal Vote, which is anticipated for 2018.

Working Group 2: Terminology, Identification, Sampling and Classification

Convenor CEN/TC 189 WG 2: Erol Güler, Turkey

The task of working group 2 is to develop on the one hand the standards for geosynthetics terminology, identification and classification, and on the other hand to harmonize sampling towards testing. Working group two has to work closely with the two product working groups (1 and 6) and also working groups 3, 4 and 5 which develop the test methods.

Given the strong cooperation with ISO/TC 221, working group 2 has to ensure that the standards developed are also well aligned with the developments in ISO, which is why most projects are developed as EN ISO standards. This process is facilitated by the fact that Erol Güler is also convenor of the corresponding working group 2 under ISO/TC 221.

Working Group 3: Mechanical Testing

Convenor CEN/TC 189 WG 3: Andrew Leech, United Kingdom

Working group 3 develops standards for mechanical testing. On the one hand these are implemented in the product specification standards developed in working group 1 and 6. On the other hand they are also necessary for the standards for durability testing, which are developed in working group 5. For this reason it is important that working group 3 works in close cooperation with these three working groups. There is also a close cooperation with the respective working group in ISO/TC 221, chaired by Daniele Cazzuffi (Italy), with a larger percentage of the standards being developed together.

Working Group 4: Hydraulic Testing

Working group 4 develops test methods for evaluating the permeability or flow properties of water and other liquids through or over geosyntetics. These test methods are important for the product specifications of working group 1 and 6, but also link to the durability testing developed in working group 5. As for working group 3 it is also important for working group 4 to work in close cooperation with these three working groups and also on international level with the respective working group in ISO/TC 221. As in working group 2 this is facilitated by Veronique Heili also being the convenor of this working group.

Convenor CEN/TC 189 WG 4: Veronique Heili, France

Working Group 5: Durability

The scope of working group 5 is to develop methods for assessing the durability of geosyn-thetic products. In the framework of the CPR and given the life time of projects where geo-synthetic products are being implemented, life times of up to 100 years can be required. It is therefore important to evaluations methods for assessing the life time of products for 25, 50 and 100 years. The exception are certain short term applications for asphalt reinforce-ment, where sometimes only temporary constructions are made.

Since durability needs to be evaluated according to the materials the geosynthetics are made of and the (soil) environment they are exposed to a large variety of different test and evaluation methods is required. Most of these test methods are primarily important for the EU market, which is why the WG 5 standards are also mostly purely European standards. Nevertheless, also working group 5 follows the activities of its respective ISO/TC 221 coun-terpart, chaired by Sam Allen (USA).

Convenor CEN/TC 189 WG 5: Jan Retzlaff, Germany

Working Group 6: Geosynthetic Barriers – General and Specific Requirements

Working group 6 develops specification standards for geosynthetic barrier layer products. Its core activities are related to the maintenance of the existing standards for CE marking and to develop new standards to ensure that novel materials or applications can be covered.

Working group 6 is finalizing the revision of its product specification standards, which cover the following applications:

  • Construction of reservoirs and dams (EN 13361:2017)
  • Construction of canals (EN 13362:2017)
  • Construction of tunnels and associated underground structures (EN 13491:2017)
  • Construction of liquid waste disposal sites, transfer stations or secondary containment (EN 13492:2018)
  • Construction of solid waste storage and disposal sites (EN 13493:2018)
  • Transportation infrastructure (EN 15382:2018)
Convenor CEN/TC 189 WG 6: Kent von Maubeuge, Germany

In parallel two new standards have been developed:

  • Construction of storage lagoons, secondary containment (above and below ground) and other containment appli-cations for chemicals, polluted water and produced liquids (EN 16993:2018)
  • Construction of underground structures (other than tunnels and associated structures) (EN 16994:2017)

All standards will be published towards the end of 2017/ beginning of 2018.

GeoMEast 2017 Sharm El Sheikh, Egypt, 15 – 20 July 2017

Chungsik Yoo, offering his plenary and the IGS Booth at the exhibition session lecture

The Technical Conference and Tradeshow GeoMEast was held July 15 – 20, 2017 in Sharm El Sheikh, Egypt. The conference was organized by the Soil-Structure Interaction Group in Egypt (SSIGE) and supported by multiple governmental, academic and technical organizations. A website for the conference is located here: http://www.geomeast2017.org/ and the confer-ence was held under the auspices of the Inter-national Geosynthetics Society.

Professor Erol Guler of Bogazici University, Tur-key (IGS council member) organized two technical workshops: one titled: Geosynthetics Engineering Barriers and a second titled: Geosynthetics Engineering: Reinforcements. Several IGS members and council members gave lectures during these sessions. Additionally, IGS Vice President- Chungsik Yoo, Professor at Sungkyunkwan University in Korea and Dr. Guler each offered plenary session lectures titled “Geosynthetics in Tunnel drainage and Waterproofing” and “ Geosynthetics: A Material Which Started a New Era in Geotechnical Engineering” respectively.

Approximately 250 people attended the conference including many national infrastructure and construction leaders. The Governor of the Sinai district where Sharm el Sheikh is located even took the time to visit the IGS booth. Work was also done in the ongoing efforts to organize an IGS chapter in Egypt with positive forward movement achieved. Egypt is a strong and growing market for the utilization of geosynthetics and hopefully this event will help to expand the proper use of geosynthetic materials.

IGS Young Members: Down to Earth – An Interview with Professor Neil Dixon

In this edition of the feature, the young members committee interviewed Professor Neil Dixon, Professor of Geotechnical Engineering at Loughborough University in the UK. Prof. Dixon has been involved with the pioneering research and implementation of geosynthetics for over 25 years. He’s served on the IGS council and as chair of the UK chapter and was even once a mentor to the current IGS president.

Name / Institution: Professor Neil Dixon, Loughborough University, UK

Specialist Field: Geotechnical Engineering: Slope stability, instrumentation and geosynthetics

What originally inspired you to enter civil engineering, and what continues to do so?

When I was growing up the Humber Bridge was being constructed nearby and I used to cycle out to watch the construction taking shape. This inspired me to think how it was being built, what materials were being used and how had it been designed. During my studies for a degree I attended a lecture on the geotechnical design for a major construction project and I became very interested in the skills needed to obtain and interpret information on the ground when only a very small percentage can ever be directly observed. This led me to do a PhD in geotechnics and I have worked as a specialist ever since. I still get excited about challenging ground engineering projects.

What do you enjoy most about working in the industry?

I particularly like the variety of challenges, the wide range of materials and design situations that require innovative solutions and the continuing need for research to improve our understanding and produce better ways of doing things.

When and where was your first involvement with geosynthetics?

I had an informal meeting with a colleague who was working on landfill designs and I realised that my background on slope stability meant that I had skills that could be used to help understand waste landfill lining interactions and hence to contribute to improved landfill designs. This initial interest led to a project with Golder Associates that employed Russell Jones as our researcher. So it was also the start of Russell’s rise to President of the IGS!

Do you have any advice for young engineers beginning their careers? What do you think are the most important skills in today’s industry?

It is important that young engineers have a good understanding of geotechnical engineering principles and that if possible they gain practical experience of investigating the ground (i.e. they see as many types of ground conditions as possible). This will help develop designs that based on an understanding of the critical mechanisms of behaviour and an understanding of how material variability can influence performance.

What hobbies and interests do you have outside work?

Walking my dog, playing golf (not as well as I would like) and reading.

Are you a fan of music?

I tend to listen to a wide range of music including classical and records from my youth, which are probably not considered cool.

 

New Technical Committee of IGS – TC-Stabilization

During its last meeting in Marrakech, the IGS Council approved the creation of a new Technical Committee, TC-Stabilization. Stabilization (or stiffening) involves the use of geosynthetics to control the deformations within a soil-geosynthetic composite in structures such as roadways. ISO TC221 has identified “stabilization” as an additional geosynthetic function. Others have contended that the actual geosynthetic function is “stiffening,” reserving the term stabilization for applications involving the improvement of the base or subgrade components of roadways. Independent of whether the term stabilization should be used as a function or as an application, it is clear that he term “stabilization” now represents a significant sub-discipline within the broader geosynthetics discipline, with its own theoretical developments, relevant properties, and research. There is a growing number of researchers and practitioners specialized in stabilization that are ready to channel their thoughts through organized forums or committees.

The number of researchers and engineers who are actively involved in various aspects involving the use of geosynthetics for stabilization is already significant, and is expected to keep growing. A good example was the recent Transportation Geotechnics and Geoecology Conference held in St. Petersburg in May 2017 where two full sessions, co-organized by the IGS, were focused specifically on stabilization. It became clear that there are significant opportunities for continued geosynthetics growth, consensus building, and research in this area.

The main objective of the new TC is to provide a forum to foster the growth, facilitate consensus, and disseminate research results on geosynthetic stabilization.

The committee leadership approved by the IGS Council is as follows:

  • Chair: Dr. Jacek Kawalec, Poland
  • Co-chair: Prof. Jorge G. Zornberg, USA
  • Co-chair: Mr. Flavio Montez, Brazil
  • Secretary: Dr. Leos Hornicek, Czech Republic

Leadership team has proposed a rather specific 2-year plan and a more general 4-year plan subject to additional refinement to be conducted during the initial 4 years of the TC (including the 2 initial years).

The 2-year plan includes the following proposed activities:

  • Initiate the program of quarterly “email meetings,” restricted only to TC-S members only. The meetings will involve addressing technical topics of relevance to the advancement of geosynthetic stabilization. During the period of one week per quarter, the technical issues will be discussed via email, with members on alert for prompt response. The communications will be consolidated after the “email meeting.” Members that do not contribute to the email meeting will be asked to leave the committee.
  • Conduct general meetings at the Geosynthetics Conferences, including the ICG (Seoul 2018). Some of general meetings will involve not only committee members, but IGS members at large. The meetings will include both organizational and technical content.
  • Organize a specialty session on Stabilization at the 11ICG in Seoul, Korea. The proposal for the specialty session has already been submitted and accepted by the conference organizers.
  • Coordinate the compilation of a special issue on “Stabilization” in one of the two official journals of the IGS.
  • Conduct a Stabilization workshop (tentatively in 2019). The papers published in the special issue on Stabilization will be invited to provide oral presentations. The specific technical agenda of the workshop will be augmented with other invited and solicited papers. This will be the first of a quadrennial series of specialty workshops on stabilization.
  • The TC chair will be in charge of the overall management of all activities, the TC Co-chairs will be in charge of at least one of the specific major activities; the TC secretary will be in charge of regular communications with TC members and the IGS Secretary.

On the other hand, the generic activities proposed for the four-year plan are as follows:

  • Conduct general meetings at the Geosynthetics Conferences, including the Regional IGS Conferences (Geo-Americas 2020, EuroGeo 2020, Geosynthetics Asia 2021).
  • Continued program of quarterly “email meetings,” restricted only to TC-S members only.
  • Organize specialty sessions on Stabilization at the Geosynthetics Conferences, including the Regional IGS Conferences (GeoAmericas 2020 in Rio de Janeiro, EuroGeo 2020 in Warsaw, Geosynthetics Asia 2021 in Taipei).
  • Conduct a Stabilization workshop in coordination with a TC of one of the IGS Sister Societies (tentatively with the

Transportation Geotechnics TC of ISSMGE).

  • Continued use of e-mail for every day communication under TC.
  • Focused development of TC website for outreach and internal TC communication.
  • Propose organization of technical sessions and short courses in events of International Sister Societies (particularly ISSMGE).
  • Compilation of existing technical literature on stabilization. Critical review and categorization of the papers. Synthesis of research trends in the area of stabilization.
  • Facilitate coordination of research among different research units across the globe. The TC could facilitate, for example, the compilation of information from multiple field monitoring sites in order to consolidate the information.
  • Collect and compare design approaches and existing practice.
  • Organize discussion forum for young professionals, incorporate young members as much as possible into TC activities.

Call for Members for the IGS Technical Committee on Stabilization

The IGS Technical Committee on Stabilization welcomes applications to join the committee. The time commitment to serve as a member of the Technical Committee is not expected to be significant. However, active participation in committee tasks will be expected from all members of the committee. If you are interested in joining the Technical Committee on Stabilization, please submit your Application form to the TC Secretary, Dr. Leos Hornicek at leos.hornicek@fsv.cvut.cz.

IGS TC-R Activities Report

The International Geosynthetics Society Technical Committee on Soil Reinforcement (IGS TC-R) had its last membership meeting at GeoAfrica, in Marrakech, Morocco, October 2017.

During these membership meetings the board informs in the open meetings the members and visitors about the latest developments in the TC-R and the interaction with other technical groups. Information about the new TC218 Reinforced Fill Structures of the ISSMGE were given by its chairman John Sankey (US). Gerhard Bräu showed the actual status of the development of Eurocode 7 which is prepared by CEN TC 250 / SC7. The actual status of ISO TC 221 WG 6 – Design using geosynthetics, especially the part for reinforcement was also presented.

Most of the time at the meeting in Marrakech was spent for the planning of the Speciality Workshop of the TC-R in 2018. TC-R is planning a seminar/workshop presenting and discussing “Hot Topics in Geosynthetics Soil Reinforcement”. It is hoped that this event will occur in Munich on 04 – 05 June 2018 in conjunction with a similar event of TC Barrier on 06 – 07 June 2018. Planning for this is ongoing and the organizers of the event are Gerhard Bräu (Chairman), Lars Vollmert (Secretary) and Jürgen Gruber (Treasurer). As the actual hot topics in the profession the following four themes were determined:

  • Veneer Cover Pietro Rimoldi, Italy
  • Bridge Abudment Jorge Zornberg, US
  • Facings of Walls and Steep Slopes Ian Fraser, UK
  • Use of Recycled and marginal soil John Sankey, US

For each of them a half day time slot is planned to have plenty of time for some main presentations and lots of discussions. The mentioned session leaders will organize the presentations for their program themselves. So please contact them directly, if you want to contribute to a theme. As result of the workshop it is expected to have the starting point for “white paper”, state-of-the-art paper or similar.

During the 11ICG in Seoul, Korea (16 – 21 Sept, 2018) the TC-R will be hosting a Special Session during the conference with the following lectures:

  • Richard Bathurst, Probabilistic analysis and design of reinforced soil walls and slopes
  • Lars Vollmert and Gerhard Bräu, Performance of geogrid reinforced and stabilized base courses
  • Pietro Rimoldi, A new analytical approach to veneer cover reinforcement
  • Yoshihisa Miyata, Seismic design of geosynthetic-reinforced soil structures

IGS TC-B Activities Report

The International Geosynthetics Society Technical Committee on Barrier Systems (IGS TCB) has been working to promote and distribute information on the newest developments in geosynthetics as a barrier.

The TC-B has been active in promoting sessions in conferences and soliciting and collecting papers on barrier topics of interest. This includes sessions as listed below:

  • GeoMEast, Egypt, July 2017
  • 19ICSMGE, Seoul, September 2017
  • GeoAfrica, Morocco, October 2017

The TC-B is actively holding membership meetings at as many locations in various regions as time and venues allow.

The last membership meetings were held at:

  • EuroGeo in Ljubljana, Slovenia on September 27, 2016.
  • GeoAsia in Delhi, India, 8 – 11 November 2016
  • GeoAfrica, Morocco, 16 October 2017

During these membership meetings the board informs in the open meetings the members and visitors about the latest developments in the TC-B, which are summarized:

  • The TCB finalized the text for a leaflet on Barrier systems. The final version accomplished by IGS is now online available or on request, and has been translated into French, Mandarin, German, Japanese, Portuguese and Spanish. Please contact IGS for copies to be distributed within chapters or at conferences or if you would like the leaflet to be available in another language.
  • New leaflets are being prepared (members volunteered to draft a version so that the editorial board can take these to the final version) and will cover:
  • A Barrier lecture
  • Barriers in agriculture Applications
  • Barriers in landfills
  • Barriers for dams, reservoirs and canals
  • Barriers in wastewater applications (here a volunteer is needed, please contact us if you are interested)
  • Mining Applications with barriers
  • A major effort of the TC-B is the planning of a 2018 TC-B seminar/workshop. It is hoped that this event will occur in Munich on 06/07 June 2018 in conjunction with a similar event of TC-Reinforcement on 04/05 June 2018. Planning is ongoing and keynote speakers are likely to be Malek Bouazza, George Koerner and Richard Brachman.

 

TC Barriers meeting at GeoAfrica 2017 in Marrakech
  • The hot topics are still being selected and ideas are always welcomed. Please contact Kent von Maubeuge directly under: kvm@naue.com.
  • The lack of literature and standard protocols for Construction/Installation Quality Assurance and Quality Control was discussed and literature de-velopment was requested. This area (CQA/CQC) is recognized to have minimal liter-ature and documentation available, as con-trasted with ISO/CEN/ASTM literature. The TC-B will have a deeper look into this and see if it is possible to improve the situation. Any available information can be sent directly to Boyd Ramsey under: boydramsey@me.com.
  • During the 11ICG in Seoul, Korea (16 – 21 Sept, 2018) the TC-B will be hosting a Barrier Work-shop and will continue to discuss the hot topics arising from the Munich TC-B workshop to allow continuing discussions. Additionally there will be a membership meeting during this four year IGS event.
