It is used to determine of the rebound deflection of flexible pavement under static load.

The complete instrument is light weight and is supplied in two parts for easy assembling and disassembling on site with help of hand tools and also it becomes easy to carry with the help of handle.

In use one end of the beam rests at a point under investigation while the beam is pivoted at the center. The free end carries a dial gauge to record the deflections and the other end is kept on the a stable platform. Because of beam ratio small deflection is magnified and recorded on the dial gauge.
