The development of methods for technical rate setting and instrumental monitoring of the geometry of the composite material surface with preserved properties after aggressive media and climatic impacts is presented. As an instrumental device for monitoring, a digital video- and photo-microscope with two hundredfold increase has been selected. Recommendations on the selection of increase of the investigated object depending on its size are formulated. A mean square deviation of the difference in height is 0.3 – 1 mm that meets the requirement for the coefficient of friction. The digital microscope was used when monitoring the quality of floor pavements of pedestrian bridge structures on the highway “Don”. Among others, the results of monitoring were used for evaluating parameters of macro-roughness of the floor pavement of the aboveground pedestrian crossing. Monitoring data were stored in the software complex for the consistent accumulation and subsequent analysis of the efficiency of the innovation use at objects of the state company “Avtodor”. In the course of monitoring, the road mobile laboratory of the Volga educational-scientific center “Volgodortrans” of the Saratov State Technical University named after Yu.A. Gagarin was used.
