The purpose of work is establishment of dynamics of development of defects at different external environments of building. The ground safest modes of motion of heavy cars. A research method is the statistical and analytical analysis of processes of education and development of defects of bridge building on the basis of rout inspections and archived materials. The quantity of heavy cars, that are revolved on the highways of Ukraine grows with every year, the quantity of routes of motion of these lorry convoys is multiplied. It is instrumental in the speed-up tearing down of bridge building which are located on motorways. Defects, that the technical state of bridges is most worsened, this: precipices of strings of strounobetonnih beams, power cracks in the roztyagneniy area of beams of heavy cars, break off to the concrete with baring and corrosion of working armature of bearing elements, cracks with lixiviating of concrete and others. It is shown on concrete examples, as passage affects bridge building of heavy cars to the lorry convoy with the observance of the specially developed mode of motion and what defects appear at unauthorized passage. It is set, that for prevention of development of old and formation of new defects from passage of heavy cars a lorry convoy needs for every concrete of heavy cars to develop the mode of motion, taking into account the technical state, structural features of building and terms of work of bearing constructions.
