Abstract: The master work took a look at the landscaping on the street. Truskavetska 15 metro station Lviv (branch number 4 of New Post). Vinyl is required for further deformation characteristics of the base ball under the coating - a “Dumbbell” truss 8 cm. The main coating is a concrete slab reinforced with metal fiber reinforced with a height of 20 cm. When forming the technical specifications, the height of the ramp was set to 10 6 cm for the entrance of cars that serve the department of Novaya Poshta No. 4 near Lviv metro station. To complete this project, it is necessary to dismantle the original coating, check the deformation characteristics of the base ball, install the support (the vibrating ball) and install a new coating. Along the way, an excavator with a hydraulic hammer was used for crushing concrete; samoskidi - for vivezennya overly concrete. The field investigation was concluded at stage 2: Stage 1 – basic coating Stage 2 – strengthening the base ball The method of monitoring was the installation of elasticity and deformation modules during the repair of the road surface. Investigation department: 1. Look at the research directly on the values of the moduli of deformation and elasticity of the foundations using various methods 2. Adapt methods for investigating the modulus of elasticity and deformation 3. Significance of deformation characteristics of fiber-reinforced concrete pavement 4. Significant deformation characteristics of the crushed stone ball under fiber-reinforced concrete. Subject of investigation: deformation characteristics of road clothing. Object of investigation: deformation and elasticity moduli of road pavement. Key words: deformation modulus, elastic modulus, road wear, repair approaches.
