PURPOSE: To prevent the reflection crack of a surface layer by, in the case of providing an asphalt surface layer on a PC plate, unitedly joining PC plates provided with each slit, and specifying the plane dimensions of the PC plate and an interval between slits. ;CONSTITUTION: An asphalt intermediate layer 46 is formed on a subbase cource 44, and a plurality of PC plates 10 is adjacently arranged on the asphalt intermediate layer 46 so that the slit 32 of the PC plate 10 may cross a road axis at right angles, and a joining means 16 for the PC plate 10 on one side is connected to a joining means 18 for the PC plate 10 on the other side with a bolt 28 for joining both the PC plates 10. Next, grout is poured into a space between the PC plate 10 and the intermediate layer 46 through a grout hole 40 for forming the asphalt surface layer 50 on the PC plate 10. The PC plate 10 is set up to be about the width of one traffic lane in longitudinal length and 1-3m in length in an axial direction of a road. In addition, the slit 32 is formed by burying a wooden thin plate in the bottom or intermediate part of the PC plate 10, and an interval between the slits is set up to be 50cm.
