Benkelman Beam
Product Description
TBT-LWC series Benkelman Beam is used to measure the pavement springback deflection value based on the overall strength of pavement evaluation an instrument. Suitable for mensurating pavement rebound deflection, to assess the bearing capacity of the road, for pavement design use, is also applicable to the construction process of the roadbed compaction degree deflection inspection.
Instrument lever support part adopts billiard bearing structure, with three different hydrocyclone classifier to satisfy different field measurement requirements. Instrument has simple structure, high sensitivity, use convenient, measured accurately, etc.
