Preface
Highway is an important infrastructure for the development of national economy. It is the most flexible mode of transportation in the whole transportation system. It has the characteristics of direct, rapid, convenient and strong adaptability. With the rapid development of China’s transportation, especially the emergence of a large number of high-grade highways, highway transportation plays an extremely important role in the national political, economic, cultural and military construction.
Expressway is an engineering structure that provides safe, fast, comfortable and economic services for vehicles and other means of transportation. After it is completed and put into use, it will suffer the repeated wear and impact of wheels and the erosion of rainstorm, flood, wind sand, ice and snow, sunlight, freeze-thaw and other natural forces, as well as some defects left in the design and construction, which will inevitably lead to the deterioration of road use function and driving service quality, and even the interruption of traffic. In order to extend the service cycle of expressway, ensure smooth flow, minimize and avoid the loss to highway users due to the above reasons, in order to adapt to the new situation of increasing traffic volume and heavy vehicles, we must take appropriate engineering and technical measures, adhere to daily maintenance, and timely repair the damaged parts in accordance with the principle of “prevention first and prevention combined”. We also need to keep the highway in good condition, smooth, clean and beautiful, carry out preventive large and medium-sized maintenance periodically, gradually change the general technical conditions, and improve the use quality and disaster resistance ability of the highway. Therefore, highway maintenance is a regular work to ensure high-speed, safe and comfortable driving. It is of great significance to strengthen highway maintenance, repair and improvement.
前 言
公路是国民经济赖以发展的重要基础设施，是整个交通综合系统中最具机动灵活的运输方式，具有直达、迅速、方便、适应性强的特点。随着我国交通事业的飞速发展，特别是大量高等级公路的出现，使公路交通运输在国家的政治、经济、文化、军事建设中发挥着极其重要的作用。
高速公路作为为汽车等运输工具提供安全、快速、舒适、经济服务的工程结构物，在建成投人使用后，因反复承受车轮的磨损、冲击，遭受暴雨、洪水、风沙、冰雪、日晒、冻融等自然力的侵蚀以及由于设计、施工中留下的某些缺陷，必然造成公路使用功能和行车服务质量的日趋退化、不适应，甚至中断交通。为延长高速公路的使用周期， 保障畅通， 尽量减少和避免由于上述原因给公路使用者带来损失，为适应交通量增大、重型车增多等新情况，必须本着“预防为主、防治结合”的原则，采取适当的工程技术措施，坚持日常保养，及时修复损坏部分，经常保持公路完好、畅通、整洁、美观，周期性地进行预防性大中修，逐步改普技术状况，提高公路的使用质量和抗灾能力。因此，公路养护是保证汽车高速、安全、舒适行驶不可觖少的经常性工作，加强公路养护、维修和改善具有十分重要意义
