During the construction of bridges, special attention is paid to geometric parameters, one of the most important parameters of the rideable bed is the evenness of the bases and coatings. Geodetic works provide an integrated approach to solving the problem of controlling the flatness of the base layers, which includes: geodetic survey of the rideable canvas, verification of working documentation, control of the copying string, geometric control of the evenness of the laid asphalt concrete floor slab for the steel concrete span and bridge deck for a metal span structure. Various options for controlling the height position of a copier string and a laid asphalt concrete pavement (using trigonometric and geometric leveling) were reviewed and tested. A priori assessment of the accuracy of the measurement results for each of the methods for monitoring algebraic difference of elevations (amplitudes) was previously performed. The article proposes a combined approach to geodetic control at all stages of work on checking the evenness of the asphalt concrete pavement.
