Dynatest Light Weight Deflectometer 3032 (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. Whereas the structure to test is composed by different layers, Dynatest LWD allows analysis for the estimation of each “layer modulus” using the Dual Plate System (DPS) and additional geophones. Transport cases available: single case for shipping fully assembled (excl. additional geophones) or multiple cases for easier handling. Key benefits of the Dynatest Light Weight Deflectometer One Person operation. Rapid test allows close test point spacing ensuring homogeneity of the test section. Surface Modulus output at time of test. The LWD App , available for both iOS and Android smartphone, gives a clear overview of the collected measurements. Assessment of both the stiffness and compaction of material with the same unit. Quality control of the subbase layers and subgrade before an overlay is applied. Testing of trench restorations to reduce the chance of settlement over time. The Light Weight Deflectometer (LWD) meets the ASTM 2583, the CD225 (UK) standard, and other international standards for determining the modulus and compaction of the material. With the trolley it is easy to bring the Dynatest Light Weight Deflectometer with you 01
