水泥混凝土材料作为桥面铺装使用历史较长，但在我国没有针对桥梁水泥混凝土 桥面铺装技术的规范、规程。根据研究成果，编制《指南》为设计施工技术人员提供 参考是有益的。我们热诚希望读者在使用《指南》过程中，不吝提出宝贵意见和建议。 希望通过讨论，对一些问题以及一些参数的合理取值再作深入的研究，不断积累资料 （请将发现的问题和修改建议意见函告四川省交通厅公路规划勘察设计研究院，成都 市武候祠横街 1 号，邮政编码：610041，以便及时修改完善），为提高桥梁水泥混凝 土桥面铺装性能、提高桥梁质量而共同努力。

前言
水泥混凝土桥面铺装层直接承受车辆轮压的作用，既是保护层，又是受力层，因 此，应具有足够的强度、良好的整体性以及抗冲击和耐疲劳的特性，同时，还应具有 防水性及温度变化的适应性能。

近年来，高速公路迅猛地向复杂地形地质条件的山区延伸，桥梁占路线总长的比 重越来越大；同时，交通流量和超载车辆不断提高，气候条件十分恶劣，因此，直接 承受车轮荷载的水泥混凝土桥面铺装面临严峻考验。传统的水泥混凝土桥面铺装结构 层，因设计、施工、环境等多种不利因素作用，导致桥梁水泥混凝土桥面铺装使用短 期内，出现大量裂缝、局部坑槽、角隅破坏、纵横缝啃边等病害，更严重者，由于混 凝土配合比设计、混凝土拌合、浇注与养护等技术落后，在混凝土浇注后的早期，就 出现大量裂缝，这些病害给行车舒适性、安全性和通行能力造成了严重影响。因此， 发展水泥混凝土桥面铺装层技术，对提高混凝土桥面铺装质量、延长桥梁结构使用寿 命，提高投资效益，具有重大意义。
