The application of bucketless bottom unloading rotor with oblique cutting knife type cutting elements on the earthmoving machine allows enhancing significantly its excavation quantities in the road construction compared with widely used machinery as bulldozers, auto-graders. A loading diagram of the forces acting on an oblique cutter installed on a bucketless bottom unloading rotor is given. The action of forces is considered with account for the complex movement made by the cutting element in space as a result of the rotational movement and the end feed on the rotor along straight-line trajectory during layer by layer excavation of the soil by rotor cutter. The dependences were obtained for determining the components of the digging force by a single oblique cutting element of a bucketless bottom unloading rotor under straight-line end feed. The bucketless bottom unloading rotor with diagonal cutting knife type cutting elements, installed on the earthmoving machine's frame, moving straightforwardly, allows not only to increase its output via rotation velocity of the bucketless bottom unloading rotor but also to excavate highly stiff soils, inaccessible for existing earthmoving machines.

A significant portion of hydrocarbons is transported by rail. At the same time petroleum products are classified as hazardous cargoes, accidents during transportation of which may lead to emergencies. The article gives an assessment of damage from emergencies in the transportation of petroleum products by rail. Assessment of economic losses, as well as damage to the environment. At damage assessment analysis of dependence of environmental damage from the time elapsed from the moment of emergency situation till the beginning of localization and liquidation of transport emergency was conducted. Technical solutions to ensure safety have been developed and proposed. The use of the proposed devices will increase the safety of transportation of petroleum products by rail. As a result of the conducted calculations the possibility of using a complex consisting of two proposed devices to ensure safety during transportation of dangerous goods has been established.

The problem of eliminating winter slips on paved roads is a topical issue today. The paper analyzes the results of tests using traditional (chloride) and non-traditional chemical reagents and their influence on the strength properties of cement concrete. In general, the formation of slipperiness on the surface of cement concrete pavements does not differ from asphalt concrete, because cement concrete can have a high moisture capacity. The pores of cement concrete readily allow moisture to penetrate, and with decreasing air temperature significant ice formation can occur in the pavement. This kind of slipperiness is very dangerous. In appearance they look like a dry coating, in fact, they penetrate deeply into the body of the coatings. Not every chemical reagent can act positively to reduce moisture. And also this process in climatic zones with a sharply continental climate especially exacerbates the likelihood of peeling of cement stone, followed by crumbling of concrete (peeling) and loss of strength due to the low stability of this material.
