3032 LIGHT WEIGHT DEFLECTOMETER (LWD) Dynatest Light Weight Deflectometer (LWD) Model 3032 is a portable dynamic plate loading device designed for compaction quality assurance (QA) and determination of the modulus of unbound or partially bound material including thin asphalt layers, unbound granular aggregate base, partially stabilized base layers, subgrade soil and etc. The LWD is suitable for testing in difficult to access areas, e.g. trenches, narrow channels, etc. Dynatest LWD is designed to determine the “surface modulus” (often termed stiffness)—a response of the underlying structure, in terms of a transient deflection, to the dynamic stress applied through a circular bearing plate. Dynatest LWD is also capable of determination of the “layer modulus” using the Dual Plate System (DPS) and additional geophones. Transport cases available: single case for shipping fully assembled or multiple cases for easier ha
