Achieving this track longevity is not just about steel tracks, sleepers and ballast. It’s also about making our soil foundations and sub layers of material strong and durable.
Traditionally, rail projects use a suite of laboratory and on-site tests to accurately measure the compaction of sub-soils and ensure that the sub-soils meet the design requirements. This is a time-consuming process which can result in significant delays.
We recently trialled Light Weight Deflectometer (LWD)equipment during construction of one of our projects. LWD equipment enables testing and immediate processing of results via signals to a control unit on site. This allows our team to check if the design requirement has been achieved and make decisions on site without delay, resulting in more efficient construction.
In May 2020, our Geotechnical Project Manager Andrew Doe presented to over 350 people, along with Professor Soheil Nazarian, an international geotechnical expert from the University of Texas at El Paso, about our experiences trialling LWD.
The webinar, jointly hosted by the Australian Road Research Board, the Australian Geomechanics Society and the National Asset Centre of Excellence, can be viewed here.
