Title:
ROAD SURFACING, METHOD OF CONSTRUCTING ROAD SURFACING, AND CONCRETE FORM
Document Type and Number:
WIPO Patent Application WO/2010/061905
Kind Code:
A1
Abstract:
Provided is road surfacing which can efficiently drain water and simultaneously retain some of the water when it is raining so as to prevent a large amount of water from being drained, and supply the retained water to a surface layer when the sun is shining, and draw water from the subgrade to reduce the temperature of the surface layer. To this end, a porous aggregate mixture (a) formed by mixing materials including a porous material and a cement based solidification material is laid to constitute a middle layer part (12), and then an asphalt mixture (b) having a water permeability function is laid to form a surface layer part (11), so as to construct a road bed (1a) which acts as road surfacing (1).
