摘要

PROBLEM TO BE SOLVED: To provide a weed-proof paving agent, a weed-proof paving method and a weed-proof paving structure which can be easily constructed and can surely prevent the growth of weeds on the surface layer of a ground surface without adversely affecting the natural environment of the surroundings such as soil and trees.;SOLUTION: A weed-proof material is formed by mixing a weed-proof paving agent including magnesium oxide, hydrated lime, powdered EVA emulsion, shirasu balloon, and at least one of granite soil, gravel and existing soil at a construction site. The weed-proof material is dispersed on the ground of the construction site to form a surface layer, and water is sprinkled on the surface layer after carrying out the leveling and compacting of a surface of the surface layer. A weed-proof paving structure is formed by curing for a predetermined time after sprinkling to harden the surface layer.;SELECTED DRAWING: None;COPYRIGHT: (C)2019,JPO&INPIT
