Description of Product
The Light Weight Deflectometer (LWD) is a portable handheld device designed for in-situ measurement of soil dynamic modulus to evaluate subgrade compaction quality. It is ideal for construction quality control and testing in railway, highway, airport and industrial building projects under dynamic loading conditions. The device is particularly well-suited for narrow or confined areas such as road-bridge transition sections, pipeline backfill zones and cable trench fills where conventional testing equipment cannot easily access.
