Special Session 1

Stabilisation Function of Geosynthetics
Organizer: Jacek Kawalec (Tensar International)

Stabilization of aggregate as new function unlike to well described and characterized function as reinforcement will need discussion on standard test procedures. New definition was recently approved by ISO TC221 and will need understanding on basic differences from reinforcement. Several researches papers on stabilization, mainly in road and railway applications could be a good foundation for specific session at conference

  1. 1.Design of grogrid stabilized paved roads based on TBR, BCR and LCR approaches: theoretical differences and comparison of results (M. Isola, P. Rimoldi, P. Pezzano)
  2. 2.Selected laboratory and field research on geogrid impact on stabilization of unbound aggregate layer (M. Grygierek, J. Kawalec)
  3. 3.Performance verification of optimized pavement Layers (M. H. Wayne, J. Kwon)
  4. 4.Aggregate - geogrid interaction in stabilization applications. How far standard laboratory index test results are from Reality (J. Kawalec)
  5. 5.Small strain effects - geogrids contribution to serviceability (Klompmaker, Quirk, Volmert)
  6. 6.Use of the stiffness of soil-geosynthetic composite as parameter governing the selection of geosynthetics in base stabilization (J. Zornberg and H. Roodi)

Special Session 2

Geosynthetics for Countermeasures against Nuclide Contamination
Organizer: Takeshi Katsumi (Kyoto University, Japan)

The proposed session will be dedicated to the recent innovative technological developments and applications of geosynthetics to be used against nuclide contaminations. Variety of innovative technologies on geosynthetics engineering (materials, systems, designs, concepts, managements, etc.) have been accumulated since Fukushima Daiichi Nuclear Power Plant accident at 2011 East Japan earthquake and tsunami, to try to overcome against nuclide contaminations. They include numerous numbers of temporary storage sites where the geomembranes and GCL were installed to contain the bags with nuclide contaminated soils and wastes generated from de-contamination works, and where required are several challenges such as immediate installations sometimes over soft grounds, application of hydraulically-impervious and air-permeable geosynthetics because of the degradation of organic fractions, wind-resistance exposed geomembranes etc. Geosynthetics are also applied at the site of damaged nuclear power plants to prepare nuclear decommissioning. The session will attract the papers on these innovative technologies which are worth of being presented at the conference, but of course will never limit to the Fukushima experiences: The contributions which are not related to Fukushima recovery are strongly welcomed to exchange ideas and experiences. The session will be organized by IGS Japan Chapter as well as IGS Technical Committee on Barrier Systems.

  1. 1.Design and maintenance of temporary storage sites and interimstoragefacilities of nuclide contaminated soils (Michio Iba and Kohei Yokota)
  2. 2.Field measurements and numerical analysys on wind-originating tensile force acting on cover sheets for temporary strage sites of decontamination waste (Masatoshi Ishida)
  3. 3.Monitoring of Capping for Radionuclide-Contaminated WastesUsing Remote-Sensing Technology (Takayuki SHIMAOKA)
  4. 4.Development of Gas-Permeable/Waterproof Sheet and Its Application as a Cover Sheet of Putrefactive-Radioactive Contaminated Waste (Masaki Nishimura)
  5. 5.Design concept of interim storage facilities for nuclide contaminated soils (Joji Hinobayashi)

Special Session 3

Electrokinetic Geosynthetics and Electro-osmosis
Organizer: Yan-feng Zhuang (Wuhan University, China)

Dredging and sludge treatment attract more and more attentions with the growing concern of environmental issues. Electro-osmosis is an efficient technique for dewatering and consolidation. Electrokinetic Geosynthetics (EKG) provide a new category of geosynthetics product, which has great potential of application. Lots of research has been going on around this area all over the world. There are great progresses as well as new challenges on the application of EKG and electrokinetic technique in geotechnical and geoenvironmental engineering. It could be an interesting topic to communicate and to inspire more enthusiasms in innovation of geosynthetics.
