摘　　要：聚丙烯纤维混凝土具有良好的抗裂性和抗渗性,特别是对水泥混凝土表面的早期开裂控制起到了良好作用从而增强了混凝土耐久性。本文结合实例介绍聚丙烯纤维混凝土桥面铺装施工技术,为今后桥面铺装聚丙烯纤维混凝土的施工提供了宝贵的经验。The polypropylene fiber concrete has excellent tensile performance, imperrneability capacity and especially the polypropylene fibers can contribute to good control of early cracking in the surface of concrete. In this paper, by way of a practical example, the construction techniques for deck retrofitting and surfacing of an old bridge with the pelypropylene fiber concrete are presented. The techniques in the paper may provide valuable experiences for similar construction of bridge deck retrofitting and surfacing in the future.
