Beckerman Beams Deflectometer

*Benkelman beam

* Determine resilient modulus value and evaluate pavement overall strength.

* The instrument is measured pavement rebound deflection value, in order to assess overallstrength of the road.
* lt is suitable for the determination of various pavement rebound deflection value, so as toassess the road carrying capacity, for the use of pavement design, in order to apply toroadbed compaction degree deflection test in the process of construction.* Leverage support part of the instrument USES the marbles bearing structure, equippedwith three different kinds of rod in order to meet the different reauirements of fieldmeasurement. instrument has many advantages, such as simple, high sensitivity, easy touse,measurement accuracy, etc.
