[Abstract]:The research of this subject is based on traffic composition investigation, pavement disease analysis and axle load spectrum analysis. Under the condition of obtaining a large number of tracking and detecting data, the factors that affect the overhaul of single base pavement section are deeply analyzed. With the help of expert experience and mechanical analysis by ANSYS software, the overhauling structural form of single base pavement section of Tanggang Expressway is obtained. Through the investigation of the disease characteristics of the single base pavement section of Tanggang Expressway, a large amount of tracking and detecting data are obtained, and the traffic composition and axle load spectrum of the Tanggang Expressway are analyzed. It provides theoretical basis for overhaul of single base pavement section of Tanggang Expressway. Based on the analysis of the disease mechanism of Tanggang Expressway in Hebei Province, a systematic and scientific evaluation index system is established, the grade of use is divided, and the experimental road scheme of Tanggang Expressway overhaul is recommended. Based on the study of the relationship between the deflection of the existing pavement surface and the equivalent modulus of the single base pavement section of Tanggang Expressway, a scientific method for determining the damage degree and the stratum of the pavement structure is put forward. Aiming at the difference of pavement grade, this paper puts forward the plan of test road overhaul corresponding to it, establishes the corresponding ANSYS analysis model, carries out theoretical mechanics analysis, and formulates the recommended structure scheme of three kinds of test road overhaul for Tanggang Expressway combined with the experience of experts.
