To provide the joint-section structure of a road in which the generation of a partial remarkable stepped section having an effect on safety traffic can be prevented on a road surface positioned at the upper section of one even when one relatively generates land subsidence in the joining section of roads having different bearing mechanisms.
The joint-section structure of the road is positioned between a concrete subgrade 30a and a crushed-stone subgrade 10. A roadbed for the crushed-stone subgrade is composed of back-filled soil and sand, and is relatively weak. A steel plate 21 fixed onto the concrete subgrade 30a by an anchor 22 is projected horizontally towards the top face of the crushed-stone subgrade 10. Asphalt 11 is laid integrally on the top face of the subgrade.
