Benkelman Beam Device offered comprises simple lever arm device that assists in measuring deflection of flexible pavements under action of loads on moving wheels. Here, the probe beam is supported through rigid reference beam that allow deflections in its probe end measured through dial indicator present on other side. The gained deflections that are measured on dial indicator are then doubled to achieving pavement deflection.
- Deflection is measured as vehicles pass over test area to beyond end of probe beam
- Reference beam having leveling adjustment for zeroing dial indicators
- Lightweight aluminum construction
- Unique design that provides for simple field set up
