The article discusses the issues of stability of pedestrian paths and staircases located on sloped areas and interacting with a complex geological environment. The features of designing construction projects on sloping areas are considered. The reasons for the occurrence of various defects and destruction on the staircase, located on the embankment of Khabarovsk, were investigated. An assessment of the stability of the structure during repair work is given. Measures are proposed to increase the stability of the structure.

The article considers a comparative analysis of the methods of accounting for the influence of heavy-duty transport on the durability of road surfaces. The methods of calculating the coefficients of reduction to the design load are analyzed in detail. The modulus of elasticity is calculated according to the method of ODN 218.046-01 using reduction coefficients according to calculations of different methods. Recommendations on the application of the most effective technical solutions in the design of highways are given.
