【摘要】：经过几十年的发展,国省干线公路是公路网中的一个重要组成部分,为国民经济带来了很大的发展,承担了大量的区域运输任务,可以说区域经济的发展离不开国省干线公路的服务。在山区国省干线不断完善的同时,许多沥青路面的使用性能逐渐下降,道路出现病害,需要进行大、中型的维修。因此,对国省干线的养护维修工作得到了普遍的关注。养护维修方法虽然多种多样,但不同的方法有不同的适应范围,以及不同的地区有不同的道路环境特点,所以,需要进行详细的调查、对比、分析,选择出即适合山区道路特点,又经济、环保的养护方法。道路养护质量的保证也是人们普遍关注的问题,所以,如何提高道路养护质量,保证沥青路面的使用性能,也是养护工作者需要重视的问题。鉴于此,本文将对山区国省道路养护方法选择和养护质量保证这两个问题进行研究。本文首先对山区道路特点进行分析,以山区某国省干线为例,进行实地检测,分析道路病害,利用路面损坏情况和路面结构承载能力这两个指标对旧路面进行评价,通过模型对实地调查数据进行计算,分析出该路段的主要道路病害情况,结合现有再生方法的适应范围,以及规范要求进行分析,得到山区道路适合就地冷再生。然后,从两个方面对沥青就地冷再生质量控制方法进行研究,一方面,从混合料设计阶段进行研究,找出最佳配合比;另一方面,从施工工艺上,归纳总结出在各个施工过程的质量控制要点。最后,通过实际的案例分析对就地冷再生的效果进行评价,结果表明,就地冷再生适合于山区国省干线。
[Abstract]:After decades of development, national and provincial trunk roads are an important part of the highway network, which has brought great development to the national economy and undertaken a large number of regional transportation tasks. It can be said that the development of regional economy can not be separated from the service of national and provincial trunk roads. While the trunk lines of mountainous countries are constantly improving, the performance of many asphalt pavements is gradually declining, and the roads are damaged and need to carry out large and medium-sized maintenance. General attention has been paid to the maintenance and repair of national and provincial trunk lines. Although there are various methods of maintenance and repair, different methods have different scope of adaptation and different regions have different road environmental characteristics, so, Need to carry on the detailed investigation, contrast, analysis, choose the maintenance method that is suitable for the mountain road characteristic, also be economical, environmental protection. The guarantee of the road maintenance quality is also the problem that people pay attention to generally, so, how to improve the road maintenance quality, To ensure the performance of asphalt pavement is also a problem that maintainers should pay attention to. In view of this, This paper will study the two problems of road maintenance method selection and maintenance quality assurance in mountainous country and province. Firstly, this paper analyzes the characteristics of mountain road, taking the trunk line of a mountainous province as an example, carries out field inspection and analyzes road diseases. Using the two indexes of pavement damage and carrying capacity of pavement structure to evaluate the old pavement, through the model to calculate the field investigation data, to analyze the main road diseases of this section, combined with the existing regeneration methods of the scope of adaptation, And the specification requirements are analyzed to get that the mountain road is suitable for local cold recycling. Secondly, the quality control method of asphalt local cold recycling is studied from two aspects. On the one hand, the best mix ratio is found from the mixture design stage. On the other hand, the main points of quality control in each construction process are summarized from the construction technology. Finally, the effect of in-situ cold regeneration is evaluated through actual case analysis, the results show that, Local cold regeneration is suitable for mountain country and province trunk line.
