PROBLEM TO BE SOLVED: To provide an antislip agent for a frozen road capable of solving the problems that conventional antifreezes (salt or the like) have insufficient antislip effects when applied to the road surface in winter and that they may cause secondary disaster such as refreezing of thawed water on the road surface, capable of avoiding environmental pollution due to salt, and having the durable antislip effect. SOLUTION: This antislip agent for the frozen road surface comprises crushed particles which are obtained by selecting a raw material from natural rock, construction-based wasted concrete scraps, tile and ceramic scraps, roof tile scraps, brick scraps, and a natural raw material and crushing the selected raw material to have a predetermined particle size.
