ANALYSIS OF THE FEASIBILITY OF USING RIGID PAVEMENT STRUCTURES DURING THE REHABILITATION OF ROADS IN UKRAINE
Abstract
Introduction. Road infrastructure is one of the key components of economic and social development of any country. Its rehabilitation is one of the important tasks of the post-war period, when roads can be damaged or destroyed. The article provides a comparative analysis of the use of rigid pavement during the restoration of roads in Ukraine in the postwar period. Problem Statement. Ensuring the reliability of road pavement. Purpose. To investigate the feasibility of using rigid pavement structures. Results. The feasibility of using rigid pavement is analyzed, the pavement designs are presented. The cost of materials is analyzed. Conclusions. A study of the advantages and disadvantages of using cement concrete in road construction was carried out, the calculation of rigid pavement was performed, the tentative mix design was selected, and laboratory tests of the physical and mechanical properties of cement concrete were carried out. The economic component in the construction and repair of highways is one of the key criteria for choosing the type of pavement, so given the current cost of bitumen in Ukraine, the use of cement concrete is a more profitable option for construction in the post-war period.
