REPAIR MATERIAL FOR ASPHALT PAVEMENT OR CONCRETE PAVEMENT
To provide a repair material for asphalt pavement or concrete pavement, which is excellent in dispersion stability of inorganic fillers, permeability into a deteriorated portion in the surface of asphalt pavement and concrete pavement, and excellent in handleability on site, and has good strength of adhesion, and a repair method for asphalt pavement or concrete pavement using the repair material having the above characteristics.SOLUTION: The repair material for asphalt pavement or concrete pavement is provided that contains a resin composition and a substantially spherical inorganic filler. The resin composition is composed of resin such as epoxy resin, acrylic resin, methacrylic resin, polyurea resin, urethane resin, and the like, and the ratio of the apparent specific gravity of the inorganic filler to the specific gravity of the resin composition is 0.5/1 to 1.6/1. The repair method for asphalt pavement or concrete pavement is also provided that includes a step of curing the repair material at room temperature after injecting the repair material into a repair object portion of the asphalt pavement or concrete pavement.SELECTED DRAWING: Figure 1
【課題】無機充填材の分散安定性、アスファルト舗装およびコンクリート舗装の表面にある劣化部分への浸透性、ならびに、現場での取り扱い性に優れ、かつ良好な接着強度を有するアスファルト舗装またはコンクリート舗装用の補修材、前記の特徴を備えた補修材を用いて、アスファルト舗装またはコンクリート舗装を補修する方法を提供する。【解決手段】樹脂組成物および略球状の無機充填材を含有するアスファルト舗装またはコンクリート舗装用の補修材であり、樹脂組成物がエポキシ樹脂、アクリル樹脂、メタクリル樹脂、ポリウレア樹脂、ウレタン樹脂などの樹脂からなり、樹脂組成物の比重に対する前記無機充填材の見掛け比重の比率が０．５／１〜１．６／１である補修材、ならびにアスファルト舗装またはコンクリート舗装にある補修目的の部分に補修材を注入した後、補修材を常温で硬化させる工程を有するアスファルト舗装またはコンクリート舗装の補修方法。【選択図】図１
