PROBLEM TO BE SOLVED: To provide a construction method for replacing a PCa slab in a runway and an apron in an airport and eliminating a step caused when constructing a new PCa slab adjacent to the existing or already replaced PCa slab temporarily by a simple configuration.;SOLUTION: In this construction method for precast concrete slab, when height of an end part of the adjacent and temporarily constructed precast concrete slab 20A is smaller than height of an end part of the existing or already replaced precast concrete slab 20 and the step H occurs, the smoothing plate 40 having one end part having thickness being equivalent to that of the step and the other end part having a tapered part 44 whose thickness is gradually reduced is formed, and the smoothing plate 40 is fixed on an upper face of the end part of the temporarily constructed precast concrete slab 20A to eliminate the step H. Furthermore, when constructing the temporarily constructed precast concrete slab 20A actually, the smoothing plate 40 is first removed and then this precast concrete slab is actually constructed.;COPYRIGHT: (C)2009,JPO&INPIT
