Granular pavement material or granular modifier of indoor and outdoor ground or indoor and outdoor coat and modified construction method

摘要

To effectively utilize a particulate modifying material made from purified water sludge as a raw material, as a material excellent in workability by granulating.SOLUTION: The purified water sludge subjected to dehydration treatment generated in purifying water at a water treatment plant is granulated with purified water sludge produced by adding improver for granulation and quick lime etc. The pavement material and the granular shape improving material 1 are laid up to a predetermined thickness on the correcting base part of the lower part of the concave part b formed by excavating the working soil at the construction site which is the outdoor ground a or the like to a predetermined depth, Stirring and crushing the whole or a part of the upper layer portion of the granular modifying material that has been incorporated, subjecting the mixture to agitation and pulverization, applying a rolling pressure treatment to form a water permeable water retentive layer, and applying a dustproof anti-Processing is performed to form a surface portion.(FIG.
