The purpose of the work is to increase the efficiency of the mechanical equipment of the road construction complex due to the improvement of structures and energy saving. Both theoretical and experimental research methods were used in the work: testing of full-scale samples, theoretical description of work processes, modeling of active loads, mathematical modeling of the work of motor graders, bulldozers, scrapers, and loaders. The results of experimental studies of the hydraulic drive of a short-base loader are given. The minimum permissible concentration of the INFINEUM C9425 additive in motor lubricants of construction and road vehicles is determined. Measures have been developed to increase the durability of crane ropes. The operation of buffer devices of cargo cranes during collisions has been studied. The efficiency of airfield snow removal equipment with GNSS systems is analyzed. A mathematical model of an axial-piston pump for diagnostics of hydraulic drives of earthmoving machines has been developed. An experimental determination of soil development resistance by chain-scraper excavators performing critical-deep cutting was carried out. Mathematical modeling of a self-propelled scraper at the beginning of soil collection was performed. Formulated energy-efficient methods of designing and modernizing machines. The calculation of the volumetric hydraulic drive of the chain worker has been performed body of an earthmoving trench machine instead of a mechanical transmission.
