The Lightweight Deflectometer is a portable, non-destructive testing instrument designed for real-time evaluation of soil compaction quality and subgrade bearing capacity. It provides fast, reliable results directly at the construction site, supporting efficient quality control during earthwork and pavement construction.
Using a controlled dynamic load, the LWD PRIMA-100 measures surface deflection and instantly calculates key stiffness and bearing parameters. This enables engineers to assess layer performance without damaging the compacted surface, making it ideal for repeated testing and immediate corrective action.
