摘要
改革开放以来,我国的航空事业得到了前所未有的发展。近些年,我国机场建设发生了新的变化,即新建机场逐年减少,老机场的维修和改造、扩建则比较迫切。结合十几年工程实践经验,提出采用钢纤维混凝土修补破损机场道面。用钢纤维混凝土这一新型高强复合材料修补破损的机场水泥混凝土道面,既可提高机场道面的抗裂性、抗弯曲、耐冲击和耐疲劳性,而又改善了机场水泥混凝土道面的使用性能,延长使用寿命,对节工程造价等具有重要的经济效益和社会效益;为提高机场道面补强与改造提供了良好的途径。
Since reform and opening up,China＇s aviation industry has witnessed unprecedented development.In recent years,China＇s construction of the airport has undergone new changes ,the new airport is reduced year by year,the old airport maintenance and improvement, expansion is more urgent.In this paper, combining more than 10 years of experience in practice,used by steel fiber reinforced concrete pavement repair damaged airport.The new steel fiber reinforced concrete high-strength composite materials repair the damaged airport cement concrete pavement, while improving Airport Road surface cracking, bending resistance, impact resistance and fatigue resistance, and improved the airport＇s cement concrete pavement performance, extended service life of the project cost, and other festival has an important economic and social benefits;to improve airport pavement reinforcement and transformation provides a good way.
