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 light weight deflectometer (LWD) is suitable for testing in difficult to access areas, e.g. trenches, narrow channels, etc.

The light weight deflectometer meets the ASTM E2583-07 (2015) “Standard Test Method for Measuring Deflections with a Light Weight Deflectometer (LWD) and ASTM E2835-11 (2015) “Standard Test Method for Measuring Deflections using a Portable Impulse Plate Load Test Device” European Union specification CEN ICS 93.020

  • One person operation
  • Rapid test allows close test point spacing ensuring homogeneity of the test section
  • Modulus output at time of test

Specifications LWD

  • Assessment of both the compaction and stiffness of material with 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
