Title:
PERMEABLE ROAD CONSTRUCTION METHOD USING PERMEABLE TOP BASE FOUNDATION
Document Type and Number:
WIPO Patent Application WO/2024/029910
Kind Code:
A1
Abstract:
The present invention relates to a permeable road construction method using a permeable top base foundation, wherein gravel and sand are filled in a drainage hole, which extends through substratum and is then connected to a roadbed, to ensure permeability, and a permeable top base foundation manufactured by a dry construction method is embedded together with sand, so that load concentrated to the drainage hole is supported by the top base foundation, and thus differential settlement can be prevented and the original shape of the drainage hole can be maintained. To this end, in the present invention: a plurality of drainage holes connected to the roadbed are provided transversely and longitudinally through substratum; a permeable top base foundation embedded together with sand is provided in each of the drainage holes; each of the top base foundations is made by dry-mixing cement and aggregate and inputting same into a mold and is given permeability in a process of vibration-compacting of the cement and aggregate; and each of the top base foundations is configured to have a conical shape, and is thus capable of inducing rainwater to flow from the substratum to the roadbed and has a supporting force against concentrated load.
