Abstract: The present invention relates to a concrete slab track of a structure in which a concrete slab manufactured by a precast method to support a rail is mounted on a base layer and, more specifically, to a concrete slab track capable of minimizing a restrictive load generated by a temperature change or drying shrinkage while effectively transferring longitudinal and transverse loads actuating on the concrete slab from a railway vehicle to the base layer, reducing constriction costs, and remarkably improving a construct ability; and a constructing method thereof. The concrete slab track includes the base layer (100) having recessed shear key bottom holes (101) on the surface; and the concrete slab (200) which is placed on the base layer (100) and recessed shear key top holes (201) on the underside. Penetration injecting holes (202) are formed on the shear key top holes (201). The shear key bottom holes (101) and shear key top holes (201) face each other, thereby forming a shear key unit. As a filling-hardening agent (300) is injected to the shear key forming unit through the penetration injecting hole (202) and hardened, a shear key resistant to the load actuating on the concrete slab (200) is formed into a form astride the top surface of the base layer (100) and the underside of the slab (200).
