Abstract

The paving material supplied into a hopper is conveyed by screw conveyors into a mold provided in the lower part of the apparatus thereby molding and laying the material. The paving material is densely compacted or consolidated in the mold, and when the paving material is conveyed under pressure further, the mold can be pushed up, and the reaction force of the conveying pressure acts to move the entire apparatus horizontally. Thus, structure having the same sectional shape as that of the mold can be formed and laid continuously on the ground.
