Light Weight Deflectometer (LWD) research at National Asset Centre of Excellence (NACoE)
Insitu Test, Global Synthetics and Foundation Specialist Group (FSG) are all industry partners in the National Asset Centre of Excellence (NACoE) research program using the Light Weight Deflectometer (LWD) and Geogrid. The research is being led by QUT Senior Lecturer, Dr. Chaminda Gallage.
The research is centred around a fully instrumented 1m x 1m soil box test at QUT Pilot Plant Facility.
In February 2018, testing began at the facility.
The National Asset Centre of Excellence (NACOE) is an initiative of the Queensland Department of Transport and Main Roads and with the Australian Road Research Board (ARRB), which is broadening to include partnerships with industry. Australian Road Research Board Principal Pavement Engineer, Jeffrey Lee, commented: “ARRB is proud to be participating this research.”
The program has a bias towards using research and testing that adopts international best practice to Australian / Queensland conditions.
PAVEMENTS
The Pavements program represents the largest proportion of the NACOE program, with roughly half the total projects and half the total investment. This program comprises a number of sub-programs, including asphalt, unbound granular and marginal materials, stabilised / modified pavements, surfacing and a number of technology projects.
The Pavements program has the potential to deliver very significant cost savings compared to current practices, allowing for more road projects to be constructed. Interim savings are being realised now, based on finding to date, with more to be realised at the completion of further trials.
The Pavements program has a strong focus on collaborating with industry to ensure implementation.
We purchased a PANDA 2 machine after using one from another laboratory. The information obtained has saved money on numerous jobs. It is reasonably priced and the after-market service has been great. Highly recommend using Insitutek.
After scouring the market, we settled on the PANDA DCP test equipment as it offered the technical capability and, moreover, the flexibility required to work in the restricted environment our project presented; overhead clearance typically at 1500mm but as low as 1200mm. We had a unique problem that required a unique solution and that’s precisely what we found through the team at Insitutek and the PANDA equipment. The ease of assembly, intuitive operability and compact nature of the equipment, made light of the numerous soundings we required across a widely dispersed area.
Insitutek imports, sells and services, unique geotech equipment that has proved of great benefit to those who use it. It has a particularly beneficial role to play for those compacting soil in infrastructure projects.

We find clients are often looking for ways to improve geotechnical testing outcomes and do it more efficiently at the same time. This drives their buying decision making. Australian Soil and Concrete Testing (ASCT) was a case in point when they were searching for Plate Load Test equipment for their upcoming Collector Wind Farm project. Some of the things that motivated them include: […]
We are excited to introduce the addition of a new Liquefaction Risk Estimation module in WebSprint©. Paired with our cutting-edge products, PANDA® and GRIZZLY®, this module enables you to assess the liquefaction risk of soils exposed to seismic stress. PANDA® Instrumented DCP: This cutting-edge tool provides dynamic penetrometer soundings, delivering precise data crucial for seismic risk evaluations. GRIZZLY® […]
The Australian Geomechanics Society is gearing up for a series of geotechnical events across VIC, WA, NSW, and SA-NT. We are thrilled to inform you that we will be sponsoring and attending these exciting geotechnical events, and we would love for you to join us. It’s a fantastic opportunity to catch up, explore our booth (VIC), and stay informed about […]
