【摘要】：随着我国高速公路建设快速发展，公路养护技术的提升也日益重要，然而我国公路养护技术研究还处于起步阶段，不能完全满足高速公路养护的迫切需要，欧美发达国家对养护规划研究起步较早，实施项目也较多，而我国只有为数不多的道路近年开展了养护规划研究。目前国内高速公路沥青路面的养护依然存在着诸多问题，具体表现为：（1）全寿命周期养护成本没有得到足够的重视；（2）缺乏科学的技术指导；（3）长期“重建轻养”思想还不同程度存在，高速公路养护投入不足。（4）延误最佳养护时机，预防性养护不及时，浪费养护经费的现象时有发生。本文参照国内外高速公路沥青路面养护规划相关研究内容，对高速公路沥青路面中长期养护规划进行了研究。以湖北省京港澳高速公路为依托，通过对现有路段路面进行全面检测以掌握其现有技术状况，交通量调查和统计，分析道路路面病害的特点和发展趋势，特别是结合历史养护情况与养护效果的分析论证，掌握其现有路面使用性能，并且进行了路面使用性能（PQI）评价、路面结构承载能力（PSSI）评价和路面老化性能评价，，研究沥青路面技术状况的发展规律，同时建立了京港澳高速公路沥青路面使用性能进行预测模型；结合京港澳高速公路沥青路面历年养护情况，分析论证几种养护对策及其养护效果，包括预防性养护技术和矫正性养护技术；科学合理地编制规划期内各年度养护对策、工程数量、养护资金投入，以延缓大修养护时间，力求养护资金投入效益最大化；研究制定针对性强、经济适用、具有前瞻性的中长期（2011-2015年）路面养护规划。项目研究成果运用于湖北省京港澳高速公路沥青路面的长期养护计划当中，具有一定的指导性。
[Abstract]:With the rapid development of highway construction in China, the upgrading of highway maintenance technology is becoming more and more important. However, the research of highway maintenance technology in China is still in its infancy and can not fully meet the urgent needs of highway maintenance. The developed countries in Europe and America started the research of conservation planning earlier and implemented more projects. However, only a few roads in China have carried out conservation planning research in recent years. At present, there are still many problems in the maintenance of asphalt pavement of expressway in China. The concrete manifestation is: 1) the maintenance cost of the whole life cycle is not paid enough attention to. (2) lack of scientific and technical guidance. (3) the long-term thought of "reconstruction and light maintenance" still exists to varying degrees, and the expressway maintenance investment is insufficient. 4) the best maintenance opportunity is delayed. Preventive maintenance is not timely, the phenomenon of wasting maintenance funds occurs from time to time. Referring to the related research contents of expressway asphalt pavement maintenance planning at home and abroad, this paper studies the medium and long term maintenance planning of expressway asphalt pavement. Based on the Beijing-Hong Kong and Macao Expressway in Hubei Province, the characteristics and development trend of road surface diseases are analyzed through the comprehensive detection of the existing road surface in order to grasp the existing technical situation, traffic volume investigation and statistics. In particular, based on the analysis and demonstration of the historical maintenance situation and the maintenance effect, the existing pavement performance is mastered, and the pavement performance is evaluated by PQI, PSSI and aging performance evaluation of the pavement structure. This paper studies the development law of asphalt pavement technology, establishes the prediction model of asphalt pavement performance of Beijing-HongKong-Macao expressway, and combines the maintenance of asphalt pavement of Beijing-HongKong-Macao expressway over the years. Several maintenance countermeasures and their maintenance effects are analyzed and demonstrated, including preventive maintenance techniques and corrective maintenance techniques, scientific and reasonable compilation of maintenance countermeasures, quantity of projects and investment of maintenance funds during the planning period in order to delay the time of overhaul and maintenance. To maximize the benefit of investment in maintenance funds; to develop targeted, economic and applicable, forward-looking long-term road maintenance plan 2011-2015). The research results are applied to the long-term maintenance plan of asphalt pavement of Jing-Hong Kong-Macao Expressway in Hubei Province.
