Light Weight Deflectometer
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.
Insitutek is our partner overseas for our test equipment. Ask them for a presentation or training for our products. I am sure you will be satisfied. They are a reliable and very kindly partner.
The PANDA probe is giving us and the construction team very useful insight with immediate feedback on the compaction being achieved on a major new rail construction project in QLD. We have two teams working daily using PANDA DCP’s and the Automatic Hammer on the rail formation, enabling real time decision making with confidence, based on the highly repeatable results.
We have been very happy with the support from Insitutek. They are knowledgeable and have been super responsive and flexible to our needs.
We see a huge opportunity for business to balance profits for shareholders with the well-being of people and the planet and we are actively encouraging our client base to think in a similar way. The global B Corp community is made up of companies building an economy that is not only sustainable but also inclusive […]
The AGS Queensland Annual Symposium was held on 29 Nov 2022 in Brisbane. Our exhibition stand was manned by Robin Power who had conversations with many of the 160 attendees. Recent advance in geotechnical engineering, engineering geology, and testing was the theme for the Australian Geomechanics Society (AGS) Queensland Chapter Symposium. The program included:
Engineers appear to be fixated on soil bearing capacity as the fundamental soil parameter for foundation design worldwide, with the assumption that the footing will behave as a rigid body. This assumption is usually not applicable for large and multi-column foundations, and in such conditions, engineers prefer flexible analysis using numerous available software. These computer […]
