Method for repairing airport pavement concrete
The invention provides a method for repairing airport pavement concrete, which specifically comprises the following steps of: mixing ultrahigh-performance cement, water and fine aggregate a, flatly paving the mixed repairing material on an old cement concrete pavement of an airport, and scraping to remove bubbles in the old cement concrete pavement; the fine aggregate b is evenly spread on the repairing material, and the spreading rate is larger than or equal to 100%; after initial setting, a concrete curing agent is spread, and geotextile or a thin film is covered for curing; according to the airport concrete repairing method, the procedures such as pavement milling, material mixing, plastering and sanding have high flexibility, external environmental factors are small, high-risk construction is not involved, particularly when the airport concrete repairing method is applied in an airport flight area, high safety is achieved, the airport concrete repairing method is beneficial to improving the airworthiness condition of the pavement in the flight area, and the airport concrete repairing method is suitable for being applied to the airport flight area. And compared with a traditional cement concrete repairing mode, construction is rapid and convenient, the influence on the flying area is small, the repairing layer is more economical and safer, and the repairing layer has the characteristics of ultra-thin layer and super early strength.
本发明提供了一种机场道面混凝土的修补方法，具体包括：将超高性能水泥、水、细集料a进行拌合，将拌合好的修复材料平铺在机场旧水泥混凝土道面上，刮平，清除其中的气泡；将细集料b均匀洒布在修复材料上，撒布率≥100％；初凝后，撒布混凝土养护剂，加盖土工布或薄膜养护；本发明的机场混凝土的修补方法中道面铣刨、材料拌合、抹面、撒砂等各道工序均具有较高的灵活性，受外在环境因素较小，且不涉及高危险性施工，尤其在机场飞行区内应用时，具有很高的安全性，有助于提高飞行区道面适航条件，保证航空器运行安全，且较传统的水泥混凝土修复方式，施工快速、便捷，对飞行区影响小，更加经济、安全，本发明的修补层具有超薄层和超早强特点。
