The topic of the article is the introduction of new materials and technologies into road construction, the goal is to improve the design of spatial reinforcement modules for use in road construction with the possibility of reducing manual labor during their installation during the construction of the roadway or complete mechanization of the process. The tasks solved in the article are to improve the spatial reinforcement modules for the construction of the roadway based on the analysis of factors affecting the strength and time characteristics of its service. Factors affecting the strength and time characteristics of the service of the spatial reinforcement module, the main materials and technologies used for the construction of the roadway in different countries of the world were analyzed. The model of calculation of strength of the spatial reinforcement module and versions of its design are proposed. It is concluded that the proposed module increases stiffness of reinforcing elements when creating roads and filtering and draining abilities of road layers, reduces specific load on the road bed and vibration on it and road-surrounding soils, time and cost of construction, provides strength of the structure when changing the terrain of the road surface and mechanizes the simultaneous manufacturing and installation of the module directly on the working section of the road.
