(57) [Summary] [Problem] The pavement has inadequate water resistance, weather resistance, water permeability and other properties, requires the use of a diluent, and when used outdoors for a long time, the pavement has a wood grain pattern. A binder for use with a wood fiber material for pavement, which can substantially eliminate or mitigate at least one problem selected from the inability to maintain a landscape for a long period of time and the feeling of walking being susceptible to temperature changes. provide. SOLUTION: This is a binder used together with a pavement wood fiber material, wherein (A) an aqueous radical polymerization type resin obtained by emulsion polymerization of a monomer having an ethylenic double bond, and (B) an aqueous urethane resin. Wherein at least one of the resin (A) and the resin (B) is a binder having a crosslinked structure. It is preferable that both the resin (A) and the resin (B) have a crosslinked structure. |
