Mud Pumping in Heavy Haul Railroads – Assessment & Control

Research Overview:

ACRI and Australian Research Council (ARC) linkage project.

Higher speed heavy haul operations impart repeated loading on the natural soil formation that can then fluidise (known as mud pumping).

If the build-up of pore water pressure becomes excessive it can cause track failure.

Examination of the factors surrounding mud pumping and the effectiveness of sub-surface drainage to prevent track instability, improve track longevity and reduce maintenance costs.

This project is scheduled to end January 2021.
