Arrangement for paving elastic surface material

Abstract

A paving arrangement for coating a base with a self-setting synthetic molding material comprises a rigid frame in the form of a shallow box having an open bottom. The frame is supported by a pair of sleigh members mounted on the lower portion of the frame in spaced relationship from each other so that the frame can be slid over the base. One of the sleigh members is shorter than the other and has its rear end terminating forwardly of the rear end of the longer sleigh member. A hopper is mounted on the frame for storing therein the molding material. A transversely elongate outlet opening is formed at the bottom of the hopper at a position rearwardly of the rear end of the shorter sleigh member and extending in the transverse direction between the inner edge of the longer sleigh member and an imaginary extension of the outer edge of the shorter sleigh member. A screed assembly is mounted on the frame rearwardly of the hopper for compacting the molding material as it is poured from the hopper outlet opening onto the base. An auxiliary sleigh member is mounted on the frame rearwardly of the shorter sleigh member and has means for maintaining the frame in a horizontal position. By such a construction, as the paving arrangement is displaced along the base such that the shorter sleigh member moves along the lateral edge of a prior course of paved surface, the molding material poured through the hopper outlet opening is dispersed over the locus of the shorter sleigh member so that the pavement can be completed without forming joints between adjoining courses of paved surfaces.
