Introduction. Paving roller-compacted concrete is a multi-component, artificially obtained stone-like material that is obtained from a paving roller-compacted concrete mixture, which is characterized by increased requirements for tensile strength at bending, waterproofing, water absorption, abrasion and frost resistance.
Applying the technology of arrangement of pavement layers from paving roller-compacted concrete, allows to achieve significant savings in energy consumption when using machines and equipment, to ensure less shrinkage of concrete during curing due to low water-cement ratio.
Problem statement. To compare the characteristics and arrangement of traditional cement concrete and paving roller-compacted concrete, to find out whether roller-compacted concrete is an alternative to traditional concrete. Since Ukraine currently lacks, with the exception of certain areas, practical experience in the construction and maintenance of roads with a surface of rolled-compacted concrete, to establish its advantages and disadvantages.
Purpose. Perform an analysis of the technology of arrangement of roller-compacted concrete. Compare the physical and mechanical characteristics of roller-compacted concrete and traditional cement concrete.
Materials and methods. In the work, the analysis of domestic and foreign sources by topic was carried out, laboratory research was carried out. An experimental study of paving roller-compacted concrete was performed, literary sources of Ukrainian and foreign origins were analyzed.
Results. The physical and mechanical characteristics of hardened cement concrete were determined and compared with traditional cement concrete.
Conclusions. The conducted review and analysis of scientific publications and technical documentation, performed experimental studies, confirmed the perspective and economic feasibility of using of rolled-compacted concrete pavement in Ukraine.
