【摘要】：目前，河南省的公路网络已经基本形成，然而在交通荷载和环境的侵蚀下，沥青路面会逐渐变得凹凸不平，特别是近年异常气候和超载车辆增多，使沥青路面出现各种形式的病害。随着时间的推移，这些病害日趋严重，若不及时进行修复，其结果将直接影响到路面的使用性能，养护工作已刻不容缓。然而目前河南省的养护工作并不规范，尚未建立标准化的养护方法，施工工艺落后，养护质量也参差不齐，养护工艺及设备不能满足高质量的养护任务，长期下去将会对行车的舒适性和安全性造成很大影响。因此对养护标准化技术工艺应用进行研究具有非常重要的现实意义。本文从河南省高速公路养护亟待解决的需要出发，，归纳、总结河南省高速路面病害类型并分析其原因；广泛调研和收集国内外在路面养护中所发展的最新技术；结合河南省的实际情况，对常见病害的养护技术进行分析，综合对比各种技术的优缺点，推荐出河南省高速公路沥青路面最常见的几种病害：裂缝、坑槽、车辙、桥头跳车的养护技术，对不同的养护技术进行了综合研究，提出了针对河南省的标准化处治工艺，内容包括原材料要求、施工机械、施工工序及验收标准等。通过对养护技术标准化的研究，使养护技术达到科学化、规范化，可以使路面在不进行大中修或改建的情况下获得更长的使用寿命，改善路面功能，提高路面服务水平，减少了整个生命周期的费用。
[Abstract]:At present, the highway network in Henan Province has been basically formed. However, due to the erosion of traffic load and environment, the asphalt pavement will gradually become uneven, especially the abnormal climate and the increase of overloaded vehicles in recent years. Make asphalt pavement appear various forms of disease. With the passage of time, these diseases are becoming more and more serious, if not repaired in time, the results will directly affect the pavement performance, maintenance work has been urgent. However, at present, the maintenance work in Henan Province is not standardized, the standardized maintenance method has not been established, the construction technology is backward, the maintenance quality is also uneven, and the maintenance technology and equipment can not meet the high quality maintenance task. Long-term will have a great impact on ride comfort and safety. Therefore, it is of great practical significance to study the application of maintenance standardization technology. Based on the urgent need of highway maintenance in Henan Province, this paper summarizes the types of high speed pavement diseases in Henan Province and analyzes the causes, and widely investigates and collects the latest technologies developed in the field of pavement maintenance at home and abroad. Combined with the actual situation of Henan Province, this paper analyzes the maintenance technology of common diseases, synthetically compares the advantages and disadvantages of various technologies, and recommends the most common diseases of asphalt pavement in Henan Province: cracks, potholes, ruts, etc. In this paper, the maintenance technology of bridgehead jumping vehicle is studied synthetically, and the standardized treatment technology for Henan Province is put forward, which includes the requirements of raw materials, construction machinery, construction procedure and acceptance standard, etc. Through the research on the standardization of maintenance technology, the maintenance technology can be scientific and standardized, which can make the pavement obtain a longer service life, improve the pavement function and improve the pavement service level without major or medium repair or reconstruction. Reduces the cost of the entire life cycle.
