Mass construction of structures is complicated on collapsing soils. The time course of
deformations in collapsing soils is determined by their moisture content. Since collapsing soils are usually in
a low moisture state, their compressive strain from external load occurs within a relatively brief time. Soil
subsidence, and equally collapsing in the water-saturated state, occurs over a longer period since these
processes are associated with water filtration through the soil column. Thus, the improvement of the quality
and efficiency of construction on collapsing soils largely depends on the proper assessment of their properties.
The paper presents the practical experience of designing a section of a big ring road. There are issues of design
features discussed, engineering-geological investigations, and soil tests with stamps given. Based on the
obtained results, the choice of structural solutions for road pavement is substantiated. Recommendations on
the design and assessment of the bearing capacity of collapsing soils are developed
