The structure of a standing plane shock wave in a polyatomic gas is investigated on the basis of kinetic theory, with special interest in gases with large bulk viscosities, such as CO2 gas. The ellipsoidal statistical (ES) model for a polyatomic gas is employed. First, the shock structure is computed numerically for different upstream Mach numbers and for different (large) values of the ratio of the bulk viscosity to the shear viscosity, and the double-layer structure consisting of a thin upstream layer with a steep change and a much thicker downstream layer with a mild change is obtained. Then, an asymptotic analysis for large values of the ratio is carried out, and an analytical solution that describes the thick downstream layer correctly is obtained.
