Title:
PERMEABLE PAVEMENT MATERIAL AND CONSTRUCTION METHOD FOR PERMEABLE PAVEMENT MATERIAL
Document Type and Number:
Japanese Patent JP2017008651
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a permeable pavement material that is less likely to deteriorate in drainage performance, and a construction method for permeable pavement material.SOLUTION: The present invention relates to a permeable pavement material 10 having: a lower layer part 10a molded by adding a binder (binding agent) to a first aggregate of 5-13 mm in grain size; and a surface layer part 10b provided on the lower layer part 10a and molded by adding a binder (binding agent) to a second aggregate of 0.85-2 mm in grain size. The permeable pavement material has a two-layer structure in which the surface layer part 10b functioning as a filter is provided on the lower layer part 10a capable of efficiently draining rainwater etc., on condition that washing processing using ozone nano-bubble water has been completed, so that the permeable pavement material can suitably function as a pavement material which is less likely to cause clogging and has little decrease in draining performance.SELECTED DRAWING: Figure 1
