The invention discloses a concrete preassembled road high in rupture strength. The concrete preassembled road comprises four concrete precast slabs; the two sides of each concrete precast slab are provided with holes used for placing steel strands; adjacent concrete precast slabs are connected via the steel strands; the diameter of the steel strand is 15.50mm; the four sides of each concrete precast slab are provided with the holes used for placing the steel strands, and adjacent concrete precast slabs are connected via the steel strands; one road surface unit is formed from the four concrete precast slabs via the steel strands and steel connecting plates arranged on the outsides of the concrete precast slabs; connecting key structures are arranged between adjacent concrete precast slabs; each connecting key structure comprises a shearing-resistant convex key and a shearing-resistant concave key matching with each other. The concrete preassembled road is convenient for transportation, and rapid and convenient for installation; road slabs can be divided into a plurality of kinds and types according to the ratio of the short edges to the long edges; and the plurality of positioning shearing-resistant connecting keys are arranged on the joint interfaces of the precast slabs so as to ensure that rupture or breakage of the road slabs is not caused under repeated action of overload vehicles.
