The invention provides a sidewalk antiskid terrace material and a construction process thereof, and belongs to the technical field of terrace material manufacturing. The sidewalk antiskid terrace material is prepared from the following components: epoxy resin, polysiloxane elastic resin, fluorocarbon resin, modified covalent organic framework nanosheets, boron nitride nanotubes, nano silicon nitride particles, nano silicon dioxide, nano zinc oxide, a modified flame retardant, attapulgite, a curing agent, an accelerant, a flatting agent, a coupling agent and a dispersing agent. According to the sidewalk antiskid terrace material, various high-performance resins are compounded with the nano filler to form a coating with a compact and uniform structure, so that the mechanical strength and wear resistance of the terrace are remarkably improved. In addition, due to the application of the modified flame retardant, the floor has a good flame-retardant effect, and the safety is improved. The whole formula and the construction process are scientific and reasonable, strong adhesion of the coating is ensured, construction is simple and convenient, curing is sufficient, and the coating is suitable for long-term use of outdoor sidewalks and has attractive appearance and practicability.

A surface structure to form an area of hard-standing and method of forming the same, comprising at least a first mesh and typically a ballast material, and possibly a second or further mesh layer, and a particulate body formed by a particulate material bound by a resin acting as an external surface for the surface structure. The mesh layers act to reinforce the relatively unitary structure, reducing damage to the particulate body that may otherwise be subject to crack propagation.

Proposed are a braille block with a QR code displayed for guiding the visually impaired and an information guidance system using the same, which more accurately provides the next movement information to the visually impaired on the basis of the movement route of the visually impaired and the entry direction into the current braille block analyzed through recognition of the QR code contained in the braille block, especially which analyzes and provides the information necessary to make corrections to the location of the braille block or corrections related to the QR code information contained in the braille block by analyzing whether the visually impaired actually move to or enter the guided braille block in the correct direction, and additionally which selects and provides customized information suitable for the corresponding visually impaired person among information contained in the QR code or content provided through the center server.
