REPAIRING METHOD OF ROAD AND PCa SLAB

摘要

PROBLEM TO BE SOLVED: To provide a method capable of being easily repaired within a short time so that an uneven step can not be again formed in an abutment and a road in the vicinity thereof and that an extension floor slab can be displaced to a PCa slab and the existing pavement remaining in an earth work section side. SOLUTION: A repairing method of the road includes a first step for eliminating the existing pavement over a part of the earth work section side from at least a part on the abutment, a second step placed to a position for eliminating the existing pavement in such a state that a first PCa slab formed in an L-shaped section having a projection area on one end makes the projection area as the existing pavement side remaining in the earth work section side, at the same time, it turns upward and that the other end of the first PCa slab is directly or indirectly received and a third step placing a second plate-like PCa slab on the first PCa slab of a bridge section side from the projection area.
