LWD Research Papers
The Lightweight Deflectometer (LWD) research papers cover the following applications:
- Flexible Pavements and Rigid Pavements
- Intelligent Compaction and In-Situ Testing (Stiffness Control)
- Mobile Crane Pad and Piling Rig Working Platforms
The last section deals with Understanding the Light Weight Deflectometer (LWD) and its Results and Comparative Studies between the Light Weight Defectometer and other Devices.

Mobile Crane Pad and Piling Rig Working Platforms
|Working Platforms – To BRE or not to BRE is the question – Burt Look Foundation Specialists Group (Brisbane, Australia) and Neil Honeyfield Port of Brisbane (Brisbane, Australia) AGS Journal – 2016|
The Building Research Establishment (BRE) produced a practice guide for working platforms for tracked plant, which has become a “standard” in the industry in the absence of any other widely published simple design method. The BRE design method does not apply for thick platforms or for soft subgrades, but continues to be used in those applications in the absence of an alternative document. A case study is discussed which applies the BRE in such a situation, but then compares with alternative methods (including the Light Weight Deflectometer) to assess the required working platform.
