[Abstract]:The Inner Mongolia Autonomous region straddles the northeast of the motherland, North China and northwest China. It is adjacent to the eight provinces of Hei, Ji, Liao, Ji, Jin, Shan, Gan and Ning, with a border line of more than 4000 km and a land area of 1.18 million square kilometers. In recent years, the highway of the main line of the autonomous region and the county level has been developed by leaps and bounds, but as an organic part of the highway network, the development of the highway from the countryside to the village is slow. At present, our district has not completely adapted to the local characteristics, economical and practical typical pavement structure system of Tongxiang Tongcun Highway, so it is urgent to study a set of perfect system according to the road construction materials, geological hydrology and climatic conditions, etc. The typical pavement structure of Tongxiang Tongcun highway is suitable for local characteristics to guide the construction of rural pastoral area road. This paper investigates the natural conditions of Tongxiang Tongcun highway, including the distribution of highway geomorphology and pavement materials, and the characteristics and indicators of highway natural regionalization. In order to guide the pavement design and construction of Tongcun-Tongcun highway in our district, the traffic grade of Tongcun-Tongcun highway in our district is classified according to the survey data of traffic condition and traffic volume observation and survey data and the research on traffic characteristics of Tongcun-Tongcun highway in our district. According to the actual characteristics of autonomous region, based on the investigation and analysis of road construction materials, traffic volume and existing road usage, this paper studies the pavement structure of small traffic volume at home and abroad, and selects the surface layer and basic material of Tongxiang-Tongcun highway in our district, based on the investigation and analysis of road construction materials, traffic volume and existing road usage conditions. Technical requirements, design parameters and so on carried out a large number of investigations and experimental studies. On this basis, the selection, composition and design parameters of roadbed and pavement materials of Tongxiang-Tongcun highway in our district are obtained, and the construction experience of Tongxiang-Tongcun highway in the past is used for reference, and the theoretical analysis and experimental verification are carried out. In combination with the climate and natural conditions in Inner Mongolia, the pavement layer and basic materials suitable for different grades of Tongxiang Tongcun Road and 13 typical pavement structure types are recommended, and the typical pavement structures of Tongxiang Tongcun Highway in our district are put forward. To make the construction of rural roads more rational and diversified. This paper analyzes the influencing factors of construction quality control of Tongxiang Tongcun highway, including the factors of highway engineering's own characteristics and construction management. The traffic grade of Tongxiang Tongcun Highway is divided into 4 levels, which provides more accurate positioning for the road grade selection in the construction of Tongxiang Tongcun Road in order to provide a more accurate location for the construction of Tongxiang Tongcun Road. The main factors affecting the service life of two kinds of pavement structures are understood, and the construction quality control points of the two types of pavement structures are determined.
