With the progress and development of social economy, China’s road and bridge in order to meet the requirements of transportation and other aspects, also carried out large-scale construction of basic bridge work. A variety of bridges not only cross the river, strait and other obstacles, bring convenience for human travel, but also ease the traffic tension in big cities, and become a beautiful landmark of the city. At present, roads and bridges include stone arch bridge, reinforced concrete box girder arch bridge and so on, from Wuhan Yangtze River Bridge, which was built in 1957, to Shanghai Nanpu Bridge, which was built in 1990s, to Qingdao Bay Bridge, which was built in June 2011. The construction of roads and bridges in China has made remarkable achievements and international recognition. It is because of the progress and innovation of construction technology and technology that the situation of high quality and high technology of road and bridge appears.
       At present, roads and bridges play a more and more important role in traffic, and there are a large number of roads and bridges in our country, so we must ensure the quality of roads and bridges, otherwise, once an accident occurs, it will seriously damage the safety of people’s lives and property, and then affect the social and economic stability, but also related to the survival of construction enterprises. In the process of road and bridge quality management, the quality of the construction stage is an important stage to ensure the construction of the whole bridge project, which determines the stability and quality of the final bridge buildings. Road and bridge construction enterprises can undertake the construction of road and bridge only if they have a high level of management and technology. In the process of ensuring the construction quality, there are many details that need to be dealt with and paid attention to, because the project construction is a more cumbersome and periodic construction process, many problems will lead to quality problems of bridge engineering, such as material problems, construction design problems, technical level problems of construction personnel, construction process problems and mechanical loss problems in construction. Therefore, it is necessary to summarize the current situation of quality problems and strengthen the quality management in the construction process, so as to ensure the quality of roads and bridges and realize the value of the project.

随着我国经济水平的飞速提升，各大城市也在不断发展，城市道路作为城市建设的一个重要部分，是整个城市的交通脉络，是城市生活和社会发展的基础，它对改善整个城市的交通环境起到了非常关键的作用。城市道路建设具有投资额大、涉及面广、带动作用强等特点，与广大市民的生产和生活密切相关，对社会各项事业的发展具有重要的促进作用，受到人们的重点关注。
       随着道路桥梁工程项目的不断规模化，在道路桥梁工程建设和建成投入使用过程中的质量管理与控制要求也在不断提高，它直接关系到工程项目的经济效益与社会效益，直接关系到城市交通的整体运行情况。道路桥梁工程建设包括众多建设项目，其每个环节都影响着工程质量。加强质量管理必须从各个环节出发，以环节质量的管理促进工程整体质量的提升；参与工程建设和运行的各方，建设项目的主管部门，建设、设计、施工、监理和运行养护单位等，需要明确并落实各自的质量责任，加强设计施工管理，做到设计规范、合理，施工工序严格按照设计要求完成，加强监理单位的科学监理，使建设项目科学决策、精心设计、精心施工、精心养护，共同提高城镇道路工程的建设和养护质量。

Due to the complexity of urban road and bridge construction process, high technical requirements and uneven quality of construction related personnel, these factors lead to a substantial increase in bridge construction risk to varying degrees. In addition, the quality of the maintenance process is directly related to the smooth progress of the entire bridge project.
     As an important part of urban infrastructure construction, the construction and maintenance quality of urban roads and bridges is directly related to the daily work and life of citizens, and even the image of the whole city. Therefore, it is necessary to improve the construction and maintenance technology of urban roads and bridges, to ensure that urban roads and bridges have sufficient loading capacity, and at the same time, to maintain coordination with the beauty of the city, so as to achieve the maximum economic and social benefits. This paper focuses on the analysis of the construction and maintenance technology and quality control of urban roads and bridges, hoping to provide reference for the construction process of urban roads and bridges in China.
      The safe use of bridges is the life of the highway. The maintenance and management of highway bridges is still a weak link in current highway maintenance and management. In order to strengthen the management of highways and bridges, we must establish the idea of “One Hundred Years Plan, Quality First”, and grasp the quality of highway bridge maintenance and management. Not only can it minimize and avoid the hidden dangers that endanger the lives and property of the people, but it is also of great significance to promote the sustainable development of highway traffic.

As a key part of highway engineering construction, road and bridge engineering plays an important role in promoting the development of our country’s transportation construction, and its construction management level has a decisive impact on the quality of road and bridge engineering. During the construction of roads and bridges, the management must deeply understand the importance of construction management, give priority to engineering quality, establish correct construction management concepts, pay special attention to construction cost management, establish a sound project management system, and strictly control the quality of road and bridge engineering.
      The rapid development of our country’s social economy has accelerated the process of urbanization. The subsequent pressure on urban traffic and roads is increasing, and the construction of urban roads is facing more severe test. Therefore, it is urgent to adjust and improve urban roads. The construction quality of subgrade and pavement has a decisive influence on the safety and stability of urban roads. However, pavement construction has become more and more complicated, and the technical requirements have become more stringent and detailed. Many new problems have appeared in the construction of subgrade and pavement engineering. During the construction of road and bridge projects, the pavement and subgrade must be completed within a short period of time in accordance with the design standards. This can not only promote the construction of the project, but also ensure the rapid development of the market economy. This requires the construction unit to clarify common problems and come up with solutions. The design unit, the supervision unit, and the construction unit are the main participants in the project, and these three parties form a working mode of mutual cooperation and supervision. Based on the actual engineering experience, this book analyzes some common problems of road and bridge quality management, and finds the most correct measures to solve the problems, so as to improve the quality management of subgrade and pavement engineering.
