Technical basis for the permeability coefficient of permeable paving material "Color Sand"
Introducing technical information about permeable blast furnace slag pavement "Color Sand"!
This document explains the technical basis for the permeability coefficient in "permeable blast furnace slag pavement (colored sand)." Our paving materials use granulated blast furnace slag as a raw material, which falls under the classification of sand and gravel. Therefore, we conducted the "constant head permeability test" to measure the permeability coefficient. The result of the constant head permeability test showed a measured value of 2.56×0.01 cm/sec. Thus, the required permeability coefficient for the sidewalk area in terms of "permeability" is a public standard value of 1.0×0.01 cm/sec. Our material exceeds this standard value by more than double, proving that it sufficiently meets the permeability performance required for sidewalk areas. [Overview] ■ The permeability coefficient was measured in accordance with the "Soil Permeability Testing Method" based on JISA1218. - Constant head permeability test... Applied to soils with relatively high permeability coefficients (sand and gravel). - Falling head permeability test... Applied to soils with relatively low permeability coefficients (clay, silt, etc.). ◎ Exceeds the standard value and sufficiently meets the permeability performance required for sidewalk areas. *For more details, please refer to the PDF document or external link page, or feel free to contact us.
