METHOD OF ASSESSING THE STRENGTH OF CEMENT CONCRETE COATING WHEN COMPARING VERSIONS OF THE DESIGN OF A HARD ROAD SURFACE WITH DIFFERENT REPAIR INTERVALS

Serhii Tsepelev

The article offers approaches for assessing the strength of cement concrete pavement when comparing options for road wear structures on highway bridges with different repair intervals. It is proposed to evaluate the residual resource of the coating, which is evaluated immediately after the commissioning of a new or renovated facility, along with measurements of evenness, roughness, and the actual intensity of car traffic. This will make it possible to assess the actual initial condition of the pavement, the reason for its difference from the design condition, and to adjust the designed strategy for optimal maintenance. Each highway bridge with a cement concrete coating should have its own unique repair strategy. An algorithm for solving the problem of choosing the most rational design of road clothing on bridges is proposed, by comparing options with different maintenance periods, based on the dynamics of changes in their operational state during the maintenance period. A method has been developed for comparing options for covering structures of hard road clothing on highway bridges with different maintenance periods, based on bringing the option from increased durability Tc2 to a structure with the same service life Ts1
