Abstract

With the development of the transportation industry, the requirements for pavement structures are increasingly demanding. Traditional semi-rigid base asphalt pavement structures often suffer from early damage issues. This paper proposes a semi-flexible low-dose cement-stabilized crushed stone base, which modifies the material properties of traditional semi-rigid bases by incorporating rubber powder, turning them into semi-flexible low-dose cement-stabilized bases. Based on the analysis of existing asphalt pavement structure design theories and methods, this study conducted an in-depth exploration aimed at the characteristics of the semi-flexible low-dose cement-stabilized base structure. The results show that the resilient modulus of the semi-flexible low-dose cement-stabilized crushed stone materials is lower than that of the semi-rigid base. Secondly, this study used finite element models to calculate and analyze the asphalt pavement with semi-flexible low-dose cement-stabilized bases under different structural parameters. By comparing the road surface deflection and stress conditions under different thickness and modulus base conditions, a reasonable pavement base structure form was derived, and reasonable thickness and modulus values were given in combination with pavement structures of different road grades.
