The dependence of contact as a function of temperature, pressure and microgeometry (roughness) of the surface of the original material, as well as the mechanical properties of the treated surfaces of the parts of road-building machinery and equipment production of building materials, products and structures. The nature of contact interaction of different crystal materials at the thermal strain effect has been discussed. The relationship of the kinetics and character of smoothing microprotrusion and kinetics of contact strength increase in pressure welding at heating has been established. The displacement microprotrusion mechanism for the second stage of the process compared to the first stage has been defined. Linear dimensions the activated surface parts and bundle slip bundle have been found by theory and confirmed by experiment enough reliably. Kinetic dependence of physical contact with the oppositely and dissimilar materials with sharply varying resistance to plastic deformation had been ascertained and determined. The mechanism crumple microprotrusions for the second stage of the process compared to the first stage has been defined. Linear dimensions of the activated surface parts and bundle slip packs have been found by theory and confirmed by experiment enough reliably.
Key words: physical contact / activation / adhesion / microplastic deformation / stresses of the second kind / slip pack
