PROBLEM TO BE SOLVED: To prevent a core material embedded in a pavement board from shorting. SOLUTION: In a rubber crossing pavement board 11 in which lower core materials 22, 23 in the crossing direction of a railroad are embedded in the inside, one core material 23 is divided in the middle between a pair of rails R, R and other core materials 22 are positioned astride over a divided part of a divided core material 23. As the core material 23 is divided, the rails are not shorted between rails R, R. As the other core material 22 resists against a bending stress in the rail way crossing direction in the divided part of the core material 23, the pavement board can secure a specified strength. If a portion facing the pavement board 11 of a fastening tool 4 is covered with an insulation cover 20, the contact of the core material 23 with the fastening tool 4 can be avoided. In the lower part of the rail R, a spacer 29 is inserted between adjacent sleepers 2, the sleeper 2 is restricted in the railway direction, the distance between the end face of the pavement board 11 end face and the fastening tool 4 is kept to prevent damage of the rubber.
