For transportation engineers, it is not always possible to avoid building on highly compressible soils. The crossing of wetlands and rivers in particular will require an important consolidation of the in-situ soil in order to avoid major slope failures within the future road and rail embankments. The pre-consolidation of the most compressible areas is crucial to prevent long term creep settlement while ensuring the infrastructure can be operated safely. The consolidated soil foundation will increase the service life of the road pavement, thus reducing life-cycle costs for the roads and railways.
Approach embankments leading to bridges can produce significant loads in subsurface soils, up to 200 kPa. These specific critical zones will require intensive ground improvement to ensure proper performance during the life of the roads or railways. The objectives of ground improvement for road and railway embankments are:

 

  • To reduce long term differential settlements;
  • To guarantee the stability of high embankments with regards to slope failure
