The construction of a properly performing road foundation requires the constituent material to have a sufficient stiffness and resistance to deformation.
It is essential that these materials are adequately compacted at their optimum moisture content to perform appropriately under load. The in-situ measurement of stiffness and state of compaction can be measured using the Light Weight Deflectometers (LWD).
The LWD has been successfully used in the assessment of unbound and bound materials in the following applications (Please note this list is not exhaustive)
PrimaAnalyser software can be used to analyse the data gathered from these applications and produce reports quickly and very easily with a simple but power software. The software analysis can be customised to meet the requirements of the user’s design standard.
