About This Product
This deflectometer applies an impulse load to a pavement surface and records its vertical deflection with load and deflection sensors. From these readings, pavement properties such as bearing capacity, layer thickness, E moduli and expected surface life are calculated, and it can also show voids under the surface or how concrete slabs are in contact. Operation is one-key at the test location, results are self-checked automatically, and data moves to a PC by USB memory key or direct connection.
