The apparatus, primarily for use on footpaths and the like that are bordered by parallel kerbs, comprises a frame 12-15 supportable on the kerbs such that it can move along the path and one or more transverse blades 31-34 mounted to the frame such that they extend across the path between the kerbs with the lower edges of the blade(s) extending at a depth below the top of the kerbs. The depth of the blade(s) may be adjustable with a blade preferably extended perpendicular to the kerbs in use. Wheels 22 may be provided to roll along the upper surface of each kerb. At least one spreader blade may be provided that extends at an angle to the kerbs, preferably with a number of spreader blades extending alternately from opposing sides of the frame. Also claimed is a method of laying and grading a sub-formation of a pathway. |
