Rockfall test in the laboratory to estimate the rock bounce capacity and the coefficient of restitution. When rock falls it bounces from the surface. It is important to know how high and how far it can bounce so that we can estimate the potential rock to infrastructure. In this test, the bounce trajectory of a rock is estimated by measuring the bounce direction and the rock velocity before and after it hits the rock surface.
