Abstract: In order to calculate the thickness of the layers containing the inserted layer, this paper first introduces the concept and representation of the boundary residual to quantitatively evaluate the size of the triangular region of the jagged boundary. Then, by discretizing the centerline of the inserted layer trajectory, the distance from the endpoint of the trajectory centerline along the tangential direction to the inserted layer boundary is calculated, so that the boundary residuals in different cases can be calculated. And at the same time, the triangular area generated at the boundary is divided and quantified by using the boundary residuals to lay the foundation for the calculation of the thickness distribution of the single-layer pavement. Finally, the thickness at the apex of the triangular surface sheet is obtained by meshing the surface of the core mold and the surface assignment of the inner and outer triangular areas and the laydown defect area in each layer of the pavement, and the average value of the thickness at the three apex locations of the triangular surface sheet is obtained as the overall thickness of the triangular surface sheet, so that the thickness analysis of the pavement as a whole can be performed.
