Abstract

The invention relates to a road void disease simulation structure and a simulation manufacturing method. A target void area of a middle structure layer is broken, a void filling layer and a control connector are laid in the target void area, and a solvent is introduced into the target void area through the control connector to dissolve the void filling layer, so that void diseases are formed in the target void area and used for simulating the void disease phenomenon of an actual road. The measurement result is more accurate, the void forming time is shorter, and pressure can be applied to void diseases of different degrees by changing the area and void depth of the target void region, so that the road bearing capacity under different void degrees is simulated. By accurately representing the formation of the void disease, the mechanical properties and stability of the road under different degrees of disease conditions can be deeply analyzed, reference is provided for maintenance and repair, maintenance resources and fund allocation are optimized, the maintenance efficiency and quality are improved, the maintenance cost is reduced, and the road traffic safety is improved.
