Installation of the "filter layer" in permeable pavement (colored sand)
Introducing technical information about permeable blast furnace slag pavement "Color Sand"!
This document explains the installation of the "filter layer" in "permeable high furnace slag pavement (colored sand)." The pavement structure of colored sand employs "water-quenched slag for civil engineering" as the filter layer. Since this "artificial sand" is produced at steelworks of major steel manufacturers, it has minimal quality variation and possesses characteristics not found in natural soil. This water-quenched slag is porous and angular in shape, exhibiting important geotechnical engineering features such as "lightweight," high "shear resistance," and "permeability." **Effects of Using Water-Quenched Slag for the Filter Layer:** - The particles have a porous shape, providing excellent permeability and water retention. - There is no strength reduction due to infiltrating water, and even if the moisture content decreases, no settlement occurs. - With a design CBR of over 20%, strong support capacity is achieved. *For more details, please refer to the PDF materials or external link pages, or feel free to contact us.*
