<p><P>PROBLEM TO BE SOLVED: To provide a slope protection method showing effects of preventing drying-up of underground water and suppressing a heat island phenomenon because of having water permeability and water retaining property in addition to easily constructing, on a slope face or the like, a weed-proof solidified base solidified in a short time with sufficient adhesiveness to concrete and asphalt while causing no cracks. <P>SOLUTION: This method for weed-proof treatment for a road slope face is carried out by mixing 50-200 kg/m<SP>3</SP>of one or more solidification reaction substances out of dolomite, cement and slaked lime and 25-50 vol.% of water, as additional numbers, into a base material comprising 40-75 vol.% of a porous inorganic material containing a total of at least 40 mass% of soluble silicic acid and/or soluble alumina, and 25-60 vol.% of a dry plant material with moisture reduced to 10 mass% or less, and spraying or placing the obtained mixed base material on a constructed surface to cover the surface. <P>COPYRIGHT: (C)2010,JPO&INPIT</p> |
