[Abstract]:With the development of China's economic construction, a large-scale highway construction has been carried out throughout the country. The annual road maintenance caused by milling planing piles up, mostly abandoned wilderness. According to statistics, the amount of old asphalt pavement materials that can be recycled each year on national and provincial trunk roads is about 160 million tons, resulting in environmental pollution and waste of resources. The research on recycled pavement structure and recycling of waste asphalt pavement materials is the trend of the times. This paper studies the structure and material characteristics of the recycled pavement of the ordinary trunk highway, taking the regenerated structure and materials of the ordinary trunk road in Shanxi Province as the research object. The research contents are as follows: 1) classifying and summarizing the existing pavement structure type and the major and medium repair structure type of Shanxi ordinary trunk highway, and reclassifying the traffic volume grade through the conversion of the traffic volume data in the past five years; The typical structure types of pavement used in different traffic volume grades are obtained: the existing pavement diseases and their causes of formation of ordinary trunk highway are analyzed, and the new pavement structure form and adaptability evaluation are given to improve various kinds of disease forms. (2) according to the main damaged form of the ordinary trunk highway with recycled surface layer and regenerated base course, the paper puts forward their design indexes, makes the axle load conversion, determines the allowable value of the design index, and puts forward the steps of parameter determination and pavement structure combination design. 3) put forward the suitable design flow and design method of cold recycled mixture, put forward the method of preserving the health of the cold recycled mixture, and put forward the feeding sequence when the mixture is mixed. Mix ratio design and later test study were carried out in the gradation range of cold recycled mixture. (4) Design of cold recycled mixture, study of road performance and construction technology, evaluation of performance of recommended structure of modified pavement and verification of solid engineering paving. The fatigue life and performance of cold recycled mixture are predicted by using the stress intensity factor and the measured data of pavement performance. Through mechanical analysis and theoretical derivation, it is studied whether the fatigue life of the pavement structure under symmetrical and partial loads can meet the axial load of equivalent load in the design life.
