【摘要】：随着高速公路建设事业的不断发展,全国高速公路总里程逐年增多。近些年,各个地区之间交流越来越频繁,而高速公路正是连接各地区的纽带,高速公路承担的运输压力越来越大,导致路面病害提前发生,这给高速管理者带来了很大困扰。与此同时,国家出台了许多关于资源节约、环境保护政策,提倡绿色养护,要求对道路资源进行合理利用,在保护环境的前提下绿色施工,所以,传统的道路养护方法已经不再适合现代道路维修,通过国内外相关研究发现就地热再生方法是一种高效、环保、低成本的预养护方法,符合绿色养护、可持续发展的要求。本文通过文献研究、理论分析、实证研究、试验分析等方法对就地热再生在重庆高速公路应用中的质量管理进行研究。研究内容主要包括:①根据重庆高速公路特点——道路材料、主要病害、地理气候条件,结合就地热再生的适用范围,对适合该技术的路段进行选择;②通过收集重庆高速公路历史养护信息,对不同预养护方法在重庆的应用效果进行对比,提出就地热再生的优势;③为了使就地热再生技术能够以较好的质量应用于重庆,本文对就地热再生质量控制关键过程进行总结分析,比如再生前旧路面评价、旧料回收处理、混合料再生、路面施工等过程。④结合重庆高速公路就地热再生实验路段,对本文研究的就地热再生技术的质量管理、质量评价方法进行实际应用,验证方法的有效性;⑤分析影响再生混合料质量的技术指标,结合实验数据,利用SPSS软件对各指标进行相关性分析,并对各个指标重要程度排序,通过计算分析得出对再生混合料性能有重要影响的是以下三个指标:空隙率、密度、沥青含量。通过本文对就地热再生技术在重庆地区推广的必要性分析,有助于重庆高速公路养护走上绿色公路、资源循环利用的可持续发展之路,并为就地热再生在重庆的应用提供有效的管理、评价方法。
[Abstract]:With the continuous development of highway construction, the total mileage of national expressway increases year by year.In recent years, the communication between different regions is more and more frequent, and the expressway is the link connecting the different regions. The transportation pressure of the highway is increasing, which leads to the road surface disease occurring in advance, which brings great troubles to the high-speed managers.At the same time, the state has issued many policies on resource conservation and environmental protection, advocating green conservation, requiring rational use of road resources, and green construction under the premise of protecting the environment.The traditional road maintenance method is no longer suitable for modern road maintenance. It is found that the geothermal regeneration method is an efficient, environmentally friendly and low-cost pre-maintenance method, which meets the requirements of green conservation and sustainable development.This paper studies the quality management of the application of geothermal regeneration in Chongqing freeway through literature research, theoretical analysis, empirical research, experimental analysis and so on.The research contents mainly include: according to the characteristics of Chongqing freeway-road materials, main diseases, geographical and climatic conditions, combined with the scope of application of geothermal regeneration, the section suitable for this technology is selected;2 through collecting the historical maintenance information of Chongqing expressway and comparing the application effect of different pre-maintenance methods in Chongqing, the advantages of geothermal regeneration are put forward in order to make the geothermal regeneration technology be applied in Chongqing with better quality.In this paper, the key processes of quality control of geothermal regeneration are summarized and analyzed, such as evaluation of old pavement before regeneration, recycling of used materials, mixture regeneration, pavement construction and so on. 4. Combined with Chongqing Expressway, the experimental section of geothermal regeneration is used.In this paper, the quality management and quality evaluation method of geothermal regeneration technology are applied in practice, and the validity of the method is verified by analyzing the technical indexes that affect the quality of recycled mixture, and combining with the experimental data,The correlation of each index is analyzed by SPSS software, and the importance degree of each index is sorted. Through the calculation and analysis, it is concluded that the following three indexes have important influence on the performance of recycled mixture: void ratio, density and asphalt content.Through the analysis of the necessity of popularizing geothermal regeneration technology in Chongqing area, this paper will be helpful to the sustainable development of the green highway and the recycling of resources in Chongqing expressway maintenance.It also provides an effective management and evaluation method for the application of geothermal regeneration in Chongqing.
