Light Weight Deflectometer – Measuring Dynamic Modulus and CBR on-site Immediately
Light Weight Deflectometer – Measuring Dynamic Modulus and CBR on-site Immediately
Engineers Australia / Australian Geomechanics Society Presentation – 12 Oct 2011
This presentation covers principles of operation of the Light Weight Deflectometer (LWD) and California Bearing Ratio (CBR) extension. The LWD device enables insitu modulus to be measured, layer by layer, during the construction process or to assess the existing condition of a pavement or foundation.
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 are using the PANDITO DCP for Level 1 site supervision, it’s very portable and we find it handy for flying into sites.

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.
