Preface

For highway maintenance work, we should implement the policy of putting prevention first and combining prevention with control, strengthen preventive maintenance, and maintain good technical conditions of roads and roadside facilities. Meanwhile we should earnestly implement the policy of prospering transportation with science and technology, and scientifically ensuring roadway maintenance, vigorously promote and apply advanced maintenance technology, mechanical equipment and scientific management methods. During highway maintenance work, we need to pay attention to resource conservation and environmental protection, focus on the safety of maintenance operation and reduce its impact on traffic. In the entire highway work, the maintenance and technical transformation of existing highways should be the top priority.
         During the rapid development of our highway industry, people have higher expectations for the quality of highway traffic. In the construction of highway and bridge projects, it is necessary for us to take maintenance and reinforcement measures, so as to better ensure the construction quality of the project, and also maximize the safety and durability of highway engineering. In recent years, our country has increased the investment in infrastructures like highways and bridges, and also put forward higher requirements for the management level of highway and bridge construction and maintenance. The construction of highways and bridges is the foundation for promoting our country's social and economic development, and is also the key to ensuring people ' s life standard. In order to improve the highway and bridge construction level, it is necessary to strengthen construction management and maintenance, discover and solve existing problems in time, and maintain traffic safety. Based on these, this book mainly analyzes and discusses the highway bridge construction and maintenance technology.

前 言

公路养护工作应贯彻“预防为主，防治结合”的方针，加强预防性养护，保持公路及其沿线设施良好的技术状况。公路养护工作应切实贯彻“科技兴交，科学养路”的方针，大力推广和应用先进的养护技术、机械装备和科学的管理方法。公路养护工作应重视资源节约和环境保护，应注重养护生产作业安全及减少对通行车辆的影响。在整个公路工作中，应把现有公路的养护和技术改造作为首要任务。
        我国公路事业快速发展的过程中，人们对公路交通的质量要求也越来越高，在公路桥梁工程建设中，为了更好地保证工程的施工质量，还需要采取养护和加固措施来加以实现，这样也能够最大限度地提高公路工程的安全性和耐久性。近年来，我国加大了对公路、桥梁等基础设施的投资力度，也对公路桥梁施工与养护的管理水平提出了更高的要求。公路桥梁建设是推动我国社会经济发展的基础，同时也是保证人民生活质量的关键。 要想提高公路桥梁建设水平， 就需加强施工管理与养护，及时发现和解决存在的问题，维护行车安全。基于此，本书主要对公路桥梁施工、养护技术进行分析探讨。
