【摘要】：20世纪80年代我国高速公路开始大规模修建,90年代以后已建成的高速公路陆续进入大、中修期,由于沥青路面的设计寿命为15-20年,现在每年需要翻修的沥青路面约占12%。由于我国目前还没有完全掌握旧沥青混合料的再生技术,每年将达到220万吨之多的旧沥青混合料废弃量,如能加以循环利用,将节省材料费用3亿元以上,而且每年需要翻修的路面是以每年15%的速度增长的。因此,针对旧沥青混合料再生技术的研究和开发,已是大势所趋。论文对普通干线公路再生路面结构及材料特性的研究,以日兰高速公路再生结构和材料作为研究对象,研究内容如下： (1)针对路面再生混合料设计进行研究,提出路面再生混合料配合比设计方法,进而研究路面再生混合料的基本性能。 (2)针对设再生面层路面结构力学特性和路面主导损坏及设计指标,并进行轴载换算、确定其设计指标的容许值,提出了设再生面层路面结构的设计方法及推荐组合。 (3)通过对再生面层施工技术与质量控制进行系统的研究,提出再生面层施工工艺、设备要求与质量检评标准。 (4)结合日兰高速公路日照段沥青路面大修工程试验段,针对混合料配合比设计和路面结构组合设计的研究结果,对再生面层试验路设计与铺筑进行总结,并对再生面层试验路原材料、混合料、现场施工质量进行检测与分析。
[Abstract]:In 1980s, China began to large-scale construction of freeways since the 1990s have been completed freeway into a large, medium repair period, due to the design life of asphalt pavement 15-20 years. At present, about 12 asphalt pavements need to be renovated every year. Because our country has not fully mastered the regeneration technology of old asphalt mixture at present, it will reach 2.2 million tons of old asphalt mixture waste every year. If it can be recycled, the cost of materials will be saved more than 300 million yuan, and the pavement that needs to be renovated every year is increasing at the rate of 15% per year. Therefore, the research and development of the regeneration technology of old asphalt mixture is carried out. It is the trend of the times. In this paper, the structure and material characteristics of the recycled pavement of the general trunk highway are studied, and the regenerated structure and materials of the Rilan Expressway are taken as the research object. The contents of the research are as follows: 1) based on the research of pavement recycled mixture design, the design method of mixture ratio of pavement recycled mixture is put forward, and then the basic performance of pavement recycled mixture is studied. 2) aiming at the mechanical properties of pavement structure with regenerated surface and the leading damage of pavement and the design index, the allowable value of the design index is determined by the conversion of axle load. The design method and recommended combination of pavement structure with regenerated surface layer are put forward. 3) through the systematic research on the construction technology and quality control of the regenerated surface layer, the construction technology, equipment requirement and quality inspection and evaluation standard of the regenerated surface layer are put forward. Combined with the test section of Rizhao section of Rizhao section of Rizhao Expressway, the paper summarizes the design and construction of the test road of regenerated surface layer according to the research results of mixture mix design and pavement structure combination design. And test and analysis of raw materials, mixture and construction quality of regenerated surface test road.
