With the rapid increase of highway mileage and the rapid expansion of the scope of use, the continuous growth of traffic flow, and the increasing road diseases, the expressway is facing the pressure of centralized overhaul and reconstruction, the task of expressway maintenance and management is becoming more and more difficult, and the demand for funds is growing. When the maintenance peak comes, how to manage and
maintain the expressway, giving full play to the economic and social benefits of the expressway,and maintaining and improving the use quality of the expressway have become more and more concerned by all sectors of society and relevant departments.

The Ministry of Transport puts forward the view that “highway construction is development, highway maintenance also is development, and it is important development”,and raised the highway maintenance management to a new height. It can be predicted that in the future, the focus of expressway construction in China will gradually shift from new construction to simultaneous construction and maintenance, and then to maintenance.

However, there is still a lack of investment in highway maintenance and management in China, and a long-term stable source of funds needs to be established; there are different maintenance management systems, and the responsibilities and rights of expressway maintenance need to be further clarified; the maintenance market is being cultivated, and a new mechanism has not yet been formed; preventive maintenance has not been popularized, and the overall technical level needs to be improved. Therefore, it is necessary to analyze the current situation and project management of expressway maintenance management in China.At the same time, the book is divided into eight chapters to explore the root causes of the problems existing in the maintenance management and project management of China’s expressway, and put forward improvement measures, so as to ensure the sound and rapid development of the maintenance management of China’s expressway.

随着高速公路通车里程的急剧增加和使用范围的迅速扩大，交通流量的持续增长，道路病害日益增加，高速公路面临集中大修和改造的压力，高速公路养护管理任务越来越艰巨、资金需求越来越大。在养护高峰期到来之际，如何管好、养好高速公路，充分发挥高速公路的经济效益和社会效益，保持和提升高速公路的使用品质，成为社会各界和有关部门愈来愈关心的问题。

交通运输部提出“公路建设是发展，公路养护也是发展，而且是重要发展”的观点，把公路的养护管理提到了一个新的高度来认识。可以预计，今后一个时期，我国高速公路建设的重点将从新建为主逐步转为建设与养护并举进而过渡到以养护为主。

然而，我国高速公路养护管理工作还存在投入不足，长期稳定的资金来源渠道有待建立；养护管理体制各异，高速公路养护的责权需进一步明晰；养护市场正在培育，新型机制尚未形成； 预防性养护尚未普及，整体技术水平还需提升。因此，非常有必要对我国高速公路养护管理现状及项目管理进行深入分析，同时，本书分八章内容将我国高速公路养护管理及项目管理中存在的问题根源进行探究，提出改进的措施，从而保障我国高速公路养护管理事业又好又快发展。

Engineering economics is the core course in the economic platform course of engineering management specialty, and also the required course of civil engineering specialty. Engineering economics is a new marginal discipline that carries out technical and economic analysis, calculation, evaluation and comparison of engineering construction projects and it selects the best scheme with advanced technology, reasonable economy, feasible practice, significant economic effect and obvious social benefit, and provides scientific basis for engineering project decision-making.

With the rapid development of China’s economy, the scale of engineering construction is getting larger and larger, and the quality requirements of engineering projects are getting higher and higher. A large number of compound talents who are familiar with both engineering technology and related knowledge and skills such as economy, management and law are needed. Therefore, engineering technology and management personnel must master certain knowledge of engineering economics.

This book tries to be simple and practical in content. It not only combines the knowledge requirements in the professional qualification examination of registered engineers, but also follows the principle of “emphasizing theory and strengthening practice” in the cultivation of undergraduate talents.

This book references and quotes a large number of domestic and foreign experts and scholars’ works, and hereby expresses our respect and heartfelt thanks to them.

Due to the limited academic level and practical experience of the editor, it is inevitable that there are some defects in the book. We would appreciate your criticism and correction.
