CONCRETE PAVEMENT SLIP RESISTANCE IMPROVING METHOD

摘要

PROBLEM TO BE SOLVED: To provide a concrete pavement slip resistance improving method capable of simply improving a slip resistance at low cost.;SOLUTION: In a concrete pavement slip resistance improving method according to this invention, at least 0.03 liter of acidic aqueous solution with 5 or less of pH per m² is spread, applied or sprayed on a concrete pavement surface. It is preferable that the acidic aqueous solution is spread, applied, or sprayed on the concrete pavement surface and the surface is left as it is for 10 seconds to 30 minutes, and subsequently acid is removed by cleaning the concrete pavement surface with water or alkaline solution.;SELECTED DRAWING: None;COPYRIGHT: (C)2016,JPO&INPIT
