Aim. This study aims to develop technological solutions for constructing road structures from EPS blocks for building embankments on soils with low load-bearing capacity.

Methods. The justification of the considered solutions is based on the application of network optimization methods and experimental studies.

Results. An original design of technological equipment is proposed to increase the efficiency of road construction works.

Conclusion. The mobile complex for the production of polystyrene foam blocks can be used for the construction of highways in remote areas with unfavorable soil and hydrological conditions and for the restoration of highways in the aftermath of natural and human-made emergencies.
