[Abstract]:After years of development, the period of highway construction in China has passed, there are a large number of highways need maintenance and maintenance at this stage, so it is imperative to study the maintenance and repair technology. In this paper, the pavement structure of cold recycled asphalt pavement is studied in combination with the scientific research project of Guizhou Provincial Traffic Bureau, "Research on the Application of Cold Recycling Technology in the Field". In this paper, the field cold recycled cement stabilized macadam base asphalt pavement is studied. Firstly, a large number of domestic and foreign literatures are read, and the research and application results of the technology are summarized and summarized to provide a reference for the later research. Then, the application status of field cold regeneration technology in Guizhou province and the adaptability of existing regeneration structure to axle load are studied. Through a comprehensive investigation of the main field cold regeneration technology application areas in Guizhou Province, the field cold regeneration machinery used in Guizhou Province is studied. The regeneration technology, the structure form and material before and after regeneration, the traffic characteristics of trunk highway and the main diseases of regenerated pavement were studied. The usage of the existing pavement structure in Guizhou Province and its adaptability to traffic axle load are studied and compared with the previous investigation and theoretical analysis. This paper compares and analyzes the difference between the actual and theoretical tolerable traffic volume of the existing cold regeneration structure in Guizhou Province, and sums up the good experience in the application of this technology in Guizhou Province, according to the analysis of the difference between the actual and the theoretical tolerable traffic volume of the existing cold regenerated structure in Guizhou Province. The shortcomings in the application of cold-regeneration technology in Guizhou province were analyzed. After the preliminary investigation of cold recycling technology in Guizhou Province, the structural design of cold recycled asphalt pavement will be optimized based on the design theory and method of new asphalt pavement. In order to make it can be used in the field of cold recycled asphalt pavement structure design. The structural design parameters of cold recycled asphalt pavement were studied by field test and indoor test, and the existing design methods were optimized by experimental road. Based on this, the design flow of cold recycled asphalt pavement structure combined with material composition is put forward. Based on the above research results, the typical structure of cold recycled asphalt pavement in Guizhou province is studied. The sensitivity analysis of traffic volume and the intensity of the base under the cold regenerated layer to the design thickness of the regenerated layer is carried out. The traffic volume below 12 million times is divided into 7 grades, and the base strength greater than 70MPa is divided into 4 grades, and the sensitivity analysis of the design parameters of subgrade and pavement in the field cold regenerative structure is carried out. Combined with the previous investigation and analysis results of Guizhou Province, a relatively reasonable structure combination form of cold recycled asphalt pavement is put forward, and the mechanical analysis and comparison of this kind of structure combination are carried out according to the finite element theory. On the basis of theoretical calculation, the typical cold recycled asphalt pavement structure with different grade of base strength and traffic volume is put forward. Through the research of this paper, it can provide the basis for the selection of asphalt pavement structure of cold regeneration in Guizhou province. This paper summarizes the applicable traffic volume of the existing structure in Guizhou province through the adaptability evaluation, and puts forward the optimized design flow of the cold recycled asphalt pavement structure based on the structural design. Through the research of typical structure, it is divided into two parts. More than one hundred typical structure forms are put forward in the third class road, which can be used in engineering practice.
