The invention relates to a visual device for simulating pavement crack repair and strength detection. The device comprises a testing machine truss, an acrylic box, a pressing rod, a bottom plate, a base, a cross beam, transparent resin concrete, a polyurethane material grouting material, a strain gauge, a pressure acquisition instrument, a computer, a high-definition camera, a triangular bracket, a vibration table, a slide way, a grouting pipe, a vacuum grouting machine, a grouting plugging cover, a hydraulic pump, a stress display and a loading plate. The invention also relates to a visualization method for simulating pavement crack repair and strength detection. The method comprises the following steps: pouring the cubic test block; grouting is conducted; closing the equipment; and carrying out graded load compression on the test block until the transparent resin concrete test block is crushed. The consumption of manpower and material resources is reduced, and meanwhile, the workload of strength parameter m
