Multilayer precast paved road

A two-layer precast paved road comprising:

• a plurality of precast lower pavement panels laid on a road panel;
• and
• a plurality of precast upper pavement panels laid on upper surfaces of the lower pavement panels,
• wherein the lower pavement panels and the upper pavement panels are arranged in a zigzag manner, and
• joint members are provided to lie between upper and lower joining surfaces of the lower pavement panels and the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through engagement or fitting between the lower pavement panels and the upper pavement panels achieved by the joint members,
• wherein cup-shaped receiving members are embedded in and fixed to upper surfaces of the lower pavement panels and lower surfaces of the upper pavement panels, and the lower pavement panels and the upper pavement panels are coupled to each other through fitting of upper half portions and lower half portions of the joint members to the respective receiving members,
• wherein the upper pavement panels and the lower pavement panels are coupled to each other with the joint members through the fitting between a plurality of protrusions formed over the entire inner peripheral surface of a cylindrical portion of the receiving members and a plurality of protrusions similarly formed over the entire outer periphery of a disk portion of the joint members, and
• wherein each of the receiving members includes a bottom surface portion with a circular shape, a side surface portion with a tapered cylindrical shape extending with a diameter increasing from the bottom surface portion toward an upper side, and the cylindrical portion with a low height standing from the side surface portion in parallel and forming an opening portion peripheral edge of each of the receiving members.
