Experimental device and method for testing grouting speed and filling degree of open joint repairing material

The invention discloses an experimental device and a method for testing grouting speed and filling degree of an open joint repairing material. A simulated open joint is constructed; the width of the simulated open joint can be adjusted by only adjusting the thickness of a washer; the physical state in the open joint is simulated through a simulation layer; the most important is that the grouting state can be directly observed through a transparent experimental panel so as to conveniently and directly observe the grouting speed and the filling degree; the selecting speed of the grouting material or the open joint repairing material can be quickened, so that the reference is provided for improving the project quality, saving the working period, avoiding the waste of the repairing material and reducing the repair workload.
