PURPOSE:To provide an erosion-preventing agent for slope, effective to strengthen the bond between rocks and improve the fixability of the deposition on ground by the film of the agent, by compounding a mixture of PVA and SBR, normal Portland cement, and cationic asphalt emulsion at specific ratios. CONSTITUTION:The objective agent can be prepared by mixing (A) a mixture of polyvinyl alcohol and styrene-butadiene rubber, (B) normal Portland cement, and (C) a cationic asphalt emulsion, at weight ratios (A:B:C) of 0.3:0.5:1. An agent having excellent adhesivity and durability to freezing and melting can be produced by the addition of the components A and B. |
