【摘要】：近十年来,随着我国国民经济的快速增长,高速公路得到了进一步的发展,通车总里程已超过美国跃居世界第一位。然而,在高速公路路龄增长的同时,路面逐渐出现多种功能性损坏,尤以横向裂缝和车辙破损最为严重,若不及时养护,会导致路面结构性损坏。本文基于浙北地区高速公路路面使用性能实测数据和交通轴载等信息,针对国内半刚性基层沥青路面特点,对高速公路项目级沥青路面预防性养护指标与决策展开研究。首先,查阅国内外相关文献资料和现行公路沥青路面养护规范,分析高速公路沥青路面预防性养护的概念及主要特征,总结国内外沥青路面预防性养护的研究现状和面临问题,了解主要病害类型、养护现状及未来发展趋势,为深入研究奠定理论基础。其次,根据预防性养护指标体系特点与作用,提出高速公路沥青路面预防性养护宏观和微观指标体系。再次,通过对国内外道路路段划分方法的研究,利用聚类分析法进行预防性养护路段划分。在路段划分的基础上,选择组合预测建立高速公路沥青路面性能衰变模型,并验证模型的可操作性和可移植性。然后,以路面使用性能为基准,同时考虑道路材料、设计、施工等工程实际因素,提出高速公路项目级沥青路面预防性养护决策矩阵和预防性养护推荐方案表,并详细分析了利用效益费用分析法确定预防性养护最佳实施时机的过程。最后,在上述研究成果的基础上,系统研究预防性养护步骤,形成一套系统性的高速公路项目级沥青路面预防性养护规划与对策设计体系,全面解决选择养护路段、确定养护措施和时机问题。
[Abstract]:In the past decade, with the rapid growth of the national economy in China, the expressway has been further developed, and the total mileage of the highway has surpassed that of the United States, ranking first in the world. The pavement gradually appears a variety of functional damage, especially the transverse crack and rut damage is the most serious, if not timely maintenance, Based on the measured data of pavement performance and traffic axle load, this paper aims at the characteristics of semi-rigid base asphalt pavement in China. The preventive maintenance index and decision-making of highway project grade asphalt pavement are studied. First of all, the relevant literature at home and abroad and the current highway asphalt pavement maintenance standard are consulted. This paper analyzes the concept and main characteristics of preventive maintenance of asphalt pavement in expressway, summarizes the research status and problems of preventive maintenance of asphalt pavement at home and abroad, and understands the types of major diseases, the current situation of maintenance and the future development trend. In order to lay a theoretical foundation for further research. Secondly, according to the characteristics and role of preventive maintenance index system, the macro and micro index system of preventive maintenance of highway asphalt pavement is put forward. Based on the study of road sections division methods at home and abroad, the preventive maintenance road sections are divided by cluster analysis method. On the basis of road sections division, the performance decay model of highway asphalt pavement is established by selecting combination prediction. And verify the maneuverability and portability of the model. Then, taking the pavement performance as the benchmark, and considering the road material, design, construction and other engineering practical factors, This paper puts forward the decision matrix of preventive maintenance of asphalt pavement of expressway project grade and the recommended schedule of preventive maintenance, and analyzes in detail the process of determining the best implementation time of preventive maintenance by using the method of benefit and cost analysis. On the basis of the above research results, the preventive maintenance steps are systematically studied, and a systematic system of preventive maintenance planning and countermeasure design for the asphalt pavement of the project grade of expressway is formed to solve the problem of choosing the maintenance section in an all-round way. Identification of conservation measures and timing.
