摘要:The paper gives an analysis of methods for estimating the spectral density of airfield pavements. The spectral density of the surface of the airfield pavement is the main criterion for estimating the roughness. This characteristic is used for the dynamic strength calculation of pavement. The paper presents analysis and comparison of the most popular methods for estimating the spectral density, and considers Burg's perspective parametric method, previously not used in aerodrome design practice.
