The development of the Far North goes hand in hand with the use of road construction equipment. The article addresses the main factors that affect the operation of this equipment in extremely cold climates. The effect of low temperatures on the operation of machines and individual units is examined. In particular, information is provided on the effect of low temperatures on operation of the hydraulic drive, power plants, and metal structures. The influence of the requirement to observe the methodological recommendations regarding the ergonomics and physiology of workers on increasing the cost of works with the use of road construction machinery has been noted.
