This paper presents the analysis of scientific and technical sources and the results of field surveys and studies of reinforced concrete slabs at the Mukachevo Plant of Durable Building Products and notes their relevance. An analysis of recent research and publications is also provided. The general information and design solutions of the investigated long-term operation MZBP are presented. The results of full-scale studies of pavement structures, in particular, pavement slabs of the Mukachevo Plant of Building Products, are presented. The calculation and design of the reinforcement of the pavement slabs in the moulding shop of the MZBP were performed. Based on the calculations and analysis of field surveys, proposals and recommendations were formulated and the technology for reinforcing reinforced concrete pavement slabs was presented. In particular, two slabs had defects and damage, and micro- and macro-cracks were found. The paper describes the technology for restoring the bearing capacity of reinforced concrete slabs produced by the Mukachevo Plant of Building Materials. The results revealed the crushing of monolithic concrete between the slabs as a result of dynamic loads of the vibrating platform and the movement of overhead cranes in the moulding shop. The results of determining the strength of concrete using a non-destructive method showed that the concrete strength is in the range of 16-17 MPa. The tests also revealed that some of the slabs have several inclined force cracks in the longitudinal ribs. Currently, the reinforced concrete slabs and the bearing capacity of the pavement are in poor condition. In addition, the owner of the territory has changed and the plant's facilities are being completely dismantled. It is obvious that the territory of the plant will be re-profiled The scientific novelty and practical significance of the research are presented and the relevant conclusions are formulated.
