Highway plays an important role in the transportation system. In recent years, with the rapid development of China's highway industry, and the construction technology of highway engineering has also been greatly improved. New methods and technologies have been fully developed and introduced. In order to create a harmonious social traffic environment, it is very important to carry out technological innovation, institutional innovation, and promote the popularization and application of highway engineering construction technology in highway construction in accordance with local conditions.

In order to improve the quality of the project, the most basic condition is to add highway engineering construction technology management. Especially in this social background, which is increasingly full of fierce market competition, it highlights the importance of strengthening the highway construction technology management, as well as its own important value. Engineering construction technology management is the core of the whole highway engineering management. We should strengthen the construction technology management to ensure the safety, high quality, low consumption and efficient completion of highway engineering construction.

This book mainly describes subgrade engineering construction technology, pavement engineering construction technology, special roadbed construction, cement concrete pavement construction, asphalt pavement construction, highway engineering project management, etc. It has certain reference value for the forward development of highway engineering.

公路在运输系统中发挥着重要的作用。近年来我国公路事业发展迅速，作为公路工程的施工技术也得到很大地进步，新方法、新技术等都得到了充分的开发和引进。因地制宜，实时进行技术创新、制度创新、促进公路工程施工技术在公路建设中的推广应用，对于创造一个和谐的社会交通环境尤为重要。

要想提高工程的质量水平，最基本的条件就是加上公路工程施工技术管理。尤其在这个日益充满激烈市场竞争的社会背景下，更是突出了加强公路工程施工技术管理的重要性，以及其自身的重要价值。工程施工技术管理是整个公路工程管理的核心，加强施工技术管理，确保安全、优质、低耗、高效地完成公路工程建设。

本书主要按照路基工程施工技术、路面工程施工技术、特殊路基施工、水泥混凝土路面施工、沥青路面施工、公路工程项目管理等内容展开叙述，对公路工程的向前发展具有一定的参考价值。

Electrical engineering and its automation technology are the synthesis of the most promising comprehensive discipline and many high and new technologies in the world. Its application range is very wide, which almost permeates all sectors of the national economy. With the development of science and technology in China, the technology of electrical automation is also improved. The era of information and intelligence has come. China is also following the trend of science and technology and the development of the times to move towards the forefront of the times. The development and extension of information technology has promoted the application field and practical scope of electrical engineering automation. This greatly accelerated the development of social industry and science and technology.

This book firstly discusses the position and function of electric power industry in the national economy, as well as the generation, development and innovation of electric power engineering and its automation. Then, the following seven chapters respectively expounds the basic principle of electric circuit, high voltage and insulation technology, electric installation engineering construction motor electrical and electrical new technology such as electrical engineering theory and electrical automation and equipment, electrical automation control, electrical automation scheduling, such as electrical automation technology, in order to provide feasible theory basis for the general electric power workers. This is also the purpose of compiling "Electrical Engineering Automation Technology". As the book contains more content, involves more cumbersome knowledge, and has more compilers, the format, depth and breadth of the contents of each chapter may not be inconsistent; and the fallacies are inevitable. Readers are invited to criticize and correct. Suggestions for improvement will be gratefully received.
