Introducing technical information about permeable blast furnace slag pavement "Color Sand"!
This document explains the "technical basis" for the pavement composition of "permeable high furnace slag pavement (color sand)." This pavement is not intended for "roadway pavement" aimed at heavy vehicle traffic, but rather is specifically designed for "pedestrian pavement" to accommodate pedestrian passage. Therefore, as a public standard, it complies with Chapter 7 of the "Pavement Design Manual," which specifically defines the selection, classification, and pavement structure of pedestrian-related road pavements under "pavements for sidewalks and bicycles." Additionally, explanations regarding "the basis for pavement composition and thickness" and "classification as pedestrian-related road pavement materials" can be found through external links.

Company information
The permeable and water-retaining pavement materials developed by Sanwa Grand Co., Ltd. allow rainwater, an invaluable water resource for the Earth, to permeate and be returned to the ground, thereby alleviating the "heat island phenomenon" in urban areas during the summer, reviving spring water, promoting the growth of trees and flowers, and regenerating "moisture of water and greenery" in the city, creating a pavement that is friendly to both people and nature. Our company aims to contribute to society as a member of a company that creates a comfortable environment through the dissemination of these environmentally friendly pavement materials, which excel in permeability and water retention. Our pavement materials are also ideal for areas with high social needs, such as "barrier-free," "disaster evacuation routes," "weed control measures," and "school route maintenance."
