Roads and Railway Infrastructure

At Menard Oceania, our wide range of techniques enables us to come up with solutions that will help you build roads and railways on solid ground.

Transport infrastructure is often confronted with the problem of building over soft, 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.

Menard Oceania’s ground improvement techniques offer a variety of cost effective solutions to address these problems.

We have a long track record of helping clients building transport infrastructure on soft soils. Installing CMC Rigid Inclusions at bridges’ abutments is something that our teams do all year long around Australia. If you drive along the Pacific Highway in NSW, chances are high that you are just near (and above) some our CMC Rigid Inclusions!

Whatever solution is chosen, the objective remains to minimise long term creep settlement and improve the shear strength of the soil. Access embankments to bridge structures often generate the most critical demand for soil treatment. The improved soil will increase and preserve the service life of the road pavement, thus reducing life-cycle costs for the roadways and structures.

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
