Abstract. The work outlines ways to intensify the production of planning and loading and unloading operations in a road-building complex using motor graders with controlled excavator equipment using comparative, logical analysis and synthesis. The study of the representativeness and technical condition of car parks, as well as indicators of their application revealed the following: the structure of machine parks contains a narrow range of nomenclature and the machines of small and medium sizes prevail; in the structure of the machine parks, the outdated planning and earthmoving machinery are represented – 52,7 %; loaders from 5,1 % to 10,5 %; hand mechanized tools – 17 %; equipment with high physical deterioration is more than 60 %; equipment leased from third-party organizations on a permanent basis is 17 %, and the total amount leased is 1,5 %.

The main idea of the new approach is the idea of forming a compact fleet of vehicles in order to reduce the cost of maintaining it by incorporating universal equipment into the composition, each unit of which can perform the functions of 2–4 machines with the complete elimination of works on re-equipment of replaceable working bodies. In the course of research, additional working equipment of a motor grader was proposed, located in front of the machine, is a loader’s working equipment consisting of a bucket, boom, thrust, hydraulic bucket and boom control cylinder, in the upper part of the rear wall of the bucket, rigidly mounted excavator equipment, represented by two brackets driven by a hydraulic motor. Inside the brackets by means of a swivel is fixed an arrow with a handle, in the coupling of which there is a hydraulic motor, which is connected to the bucket. Lifting and lowering excavator equipment is performed by two hydraulic cylinders, hinged to the brackets and the boom.

Forecast calculations showed that the cost of a modular multifunctional motor grader will on average be about 4 million rubles. The volume of capital investments for the purchase of a compact fleet of vehicles for an average enterprise of a road-building complex in the urban economy based on the use of multi-functional modular equipment will amount to approximately 24 million rubles. The payback period is 2–2,5 years.

As a result of the research, the composition and structure were determined, the main ways of intensifying the planning and loading and unloading operations in the road-building complex with the use of motor graders with controlled excavator equipment were proposed.

Keywords: road-building complex; planning and loading and unloading operations in a road-building complex; processes of intensifying the production of low-volume road-building works; strategy; mechano-leveling; productivity; improving the efficiency of technological processes in road construction using machines of increased versatility
