A precast concrete slab for sequence of a precast slab track, a structure and a construction method thereof are provided to improve stability of the track, to restrict relative displacement between the precast concrete slab and a rail and breakage of a connection portion against repeated load, and to cut down repairing expenses by continuously and integrally connecting the precast concrete slabs. A structure of a precast concrete slab(2) includes the precast concrete slab installed on a ground or a foundation(1) by a support bar, a connection steel rod(3) inserted to a steel rod insertion hole(23) of the precast concrete slab with a nut assembling screw to connect the precast concrete slabs by bolting, and a filler(4) charged and hardened between a lower part of the precast concrete slab and the ground or the foundation and a connection clearance of the precast concrete slabs. Assembling apparatus seating parts are arranged at regular intervals and protruded on the precast concrete slab.
