NACOE Releases Draft Technical Note – Guidance on Use of Light Weight Falling Deflectometers (LWDs) to be Accepted as an Alternative Method for Verification of Earthworks Compaction Requirements – June 2021
National Asset Centre of Excellence (NACOE), a collaboration of Queensland Department of Transport and Main Roads and the Australian Road Research Board (ARRB), has released their final report for the Best practice in compaction quality assurance for pavement and subgrade materials – P60 project. Importantly, in Appendix A of this report, is the Draft Technical Note – Guidance on Use of Light Weight Falling Deflectometers (LWDs) to be Accepted as an Alternative Method for Verification of Earthworks Compaction Requirements – June 2021.
This draft technical note provides guidance on implementation of Light Weight Deflectometers including a flow chart showing key steps for assessment/derivation of equivalent acceptance thresholds for LWD use (in lieu of traditional (density) testing minimum thresholds included in MRTS04 – General Earthworks).
We believe this “How to” guide will be very useful for industry on projects across the country. You can visit our website to access the full report and other resources.
If you have any feedback and thoughts on the Draft Technical Note, we’d love to hear them! Contact us.
Since hiring the LWD I have used it on numerous jobs in a wide variety of material types all over WA. The ability to give “real time” test results have worked particularly well for me as i can show my clients numerical values which gives them a direct understanding of some of the benefits using Betta Roads has brought to their road construction projects. The feedback I have been receiving over the last few months has lead me to purchase the LWD and incorporate its use as an integral part of our projects.
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.
We find the Insitutek team extremely helpful and their knowledge of the equipment and its capabilities is a great resource for our staff.

A bridge approach transition zone is the area where a road or railway track transitions from the rigid structure of a bridge to the flexible embankment or road pavement, aiming to minimize abrupt changes in stiffness and potential issues like differential settlement.
The 5th International Conference on Transportation Geotechnics (ICTG), held in Sydney, marked a milestone in the geotechnical and transportation engineering community. Organized by the UTS Transport Research Centre (UTS-TRC), this prestigious event brought together over 450 delegates from 30 countries, making it a truly global gathering for experts in the field.
The ANCOLD 2024 Conference, held in Adelaide, brought together industry professionals in dam engineering, safety, and sustainability. With 624 delegates in attendance, the event provided a collaborative platform for experts to exchange knowledge on the latest developments in dam infrastructure, safety protocols, and environmental considerations. Key discussions focused on advancing dam engineering practices in response to climate change, improving risk-informed decision-making, and exploring new innovations in dam safety.
