Chair: Patrick BOISSON, Chair of PIARC TC 4.3 Earthworks, France
Room: South Hall 2, 2nd floor
Did you know that Earth Structures and therefore earthworks represent up to 80% of the linear of the infrastructures in the world? When a natural hazard hit a transportation infrastructure, almost the overall of the disasters are linked to an Earth Structure: embankments, natural slopes, cuts, etc.
The Technical Committee 4.3 Earthworks worked during 4 years on three topics.
1. The resilience of earthworks to the effects of climate change and in particular how to increase the resilience of Earth Structures against natural hazards
3 deliverables were produced:
- an unprecedented and very complete bibliographic study in this field,
- a compilation of case studies,
- and finally, a report which propose a methodology to improve the resilience of Earth Structure against Natural Hazards.
2. Techniques and innovations
Because it is confident in the ability to achieve better earthworks in the future, the TC has produced 2 documents that focus on:
- a compilation of 36 case studies of recent unusual techniques and innovations,
- a report that makes sense between Techniques, Innovation and Improving Resilience.
3. The writing of a Practical Manual on Earthworks
The Manual, although there are still a few chapters to write, offers a good idea of earthmoving techniques.
During the first part of the session, all these works were presented. In the second part, the floor was given to 4 authors from Czech Republic, Canada- Québec, Spain and Japan, who emphasized the urgent need to adapt Earthworks to climate change and futures challenges in this domain.
The final presentation was made by Mitsuru YAMAZAKI (Japan), winner of the PIARC Prize for "Best Innovation" supported by Belgium.
