Title:
TESTING APPARATUS AND TESTING METHOD FOR VERIFYING SUSTAINABILITY OF WATER PERMEATION PERFORMANCE OF PERMEABLE PAVEMENT
Document Type and Number:
WIPO Patent Application WO/2022/154633
Kind Code:
A1
Abstract:
The present invention relates to a testing apparatus and a testing method for verifying the sustainability of the water permeation performance of a permeable pavement, and the objective of the present invention is to verify, in an environment which is the same as that of a site, how long the water permeation performance of a permeable pavement can be sustained against impurities at sites such as actual roads and sidewalks at which pavement is used. In addition, the present invention provides a permeable sheet below the permeable pavement so that the result of a test for verifying the sustainability of the water permeation performance can be exhibited to be the same as that of a site at which blocks are provided. To this end, the present invention comprises: a table on which the permeable pavement can be put according to a testing method specified in KS F4419 (an indoor constant head permeability coefficient testing method), KS F2394 (an in-situ permeability testing method for the permeable pavement) and ASTM C 1701 (an in-situ infiltration capacity testing method); a fixing device for fixing the permeable pavement and enabling four sides of the pavement to be in close contact therewith; a body for fixing pavement, when vibration is applied thereto, through the body and springs so that impact can be received; a water discharge device allowing permeation so that the amount of water having permeated therethrough can be measured according to a permeability test result; and a separate vibration generator capable of applying vibration to the pavement.
