对日本TAF环氧沥青在东沙特大桥钢桥面铺装的应用研究

随着桥梁技术的不断发展,大跨径桥梁的跨径记录不断被刷新。桥面铺装技术一直是大跨径桥梁建设的关键技术之一。环氧沥青混合料铺装层以其强度高、刚度大、高温抗塑性和低温抗裂性能好、抗疲劳性能好等优点,广泛应用于国内大跨径钢桥面铺装。文章结合广州东沙特大桥应用日本TAF环氧沥青混合料进行钢桥面结构层铺装工作实践,总结了日本TAF环氧沥青混合料在东沙特大桥钢桥面铺装的施工工艺。

Application Research of Japanese TAF Epoxy Asphalt Concrete in Deck Pavement of Dongshate Bridge

With the development of bridge technology,the span of large span bridge is renewed constantly.Deck pavement has always been one of the key technologies.Epoxy Asphalt Concrete is widely used as it has better strength,stiffness,plasticity-proof under high temperature,crack-resistance under low temperature and anti-fatigue performance.The article summaries the construction techniques of the application of Japanese TAF Epoxy Asphalt Concrete in Guangzhou Dongshate Bridge combining the practice in deck pavement.
