Cold asfaltobetonny mixes which unlike standard mixes prepare without drying and heating of a mineral component are developed. Advantages of these mixes are that they is better, than standard mixes cooperate with a damp repaired covering and in the course of warehousing don't demand performance of actions for prevention of caking of a mix. Mixes are intended for timely localization of the centers of the destruction appearing on pavings in the early spring and autumn.

Keywords: emergency repair of pavings, hollows and sags, surface-active substances, razzhizhenny bitumen, cold asfaltobetonny mix.

The problem of restoring gaps in socio-economic data. Used konnektivistskie principles describe multilevel relationships between socio-economic targets for restoring missing data. Proposed fuzzy method of filling gaps in the data socio-economic parameters based on the analysis and formalization in terms of fuzzy logic relationships between the parameters of the same type in other network objects. To justify the effectiveness of an example implementation of the method on data from rural areas of the Volgograd region.

Carbothermal synthesis method on substrates of a-Al2O3 thin film with sublayers ZnO: Ga, using copper as a catalyst for the arrays obtained by varying the zinc oxide rod morphology. It was established that growth of the rods occurs direction perpendicular to the substrate using a thin (~ 1 nm) layers of the catalyst. With increasing thickness of the catalyst layer to 3 nm rods growth occurs at an angle to the surface of the rod with a mutual orientation in the plane of the substrate surface at angles that are multiples of 60 °. Also, the selectivity demonstrated growth ZnO rods arrays on portions of the substrate coated with the catalyst.

In the present work we have carried out studies of the processes of growth of zinc oxide nanorods by hydrothermal method on silicon substrates. As sublayer catalyst used growth caused by laser deposition of zinc oxide, various thicknesses. Studied selective growth of nanorods on the microstructure of thin-film sub-layers of zinc oxide obtained by laser deposition. The optimal conditions for the synthesis of: the concentration of Zn (NO3) 2 - 0.4 mol / l, hexamethylenetetramine - 0.4 mol / l, the concentration of NH3 · H2O - 0,01 mol / L -0.01, process time 4:00, the process temperature is 80 ° C. Sublayer thickness of zinc oxide, as shown by experiment, the growth of the rods has no noticeable effect. Oriented arrays of nanorods were obtained up to 500 nm and a diameter of 60-150 nm.
Keywords: zinc oxide nanorods and micro-oriented arrays of nanorods, hydrothermal synthesis method, selective growth, thin film underlayer.

The analysis of operating conditions of transport systems shows that constantly increasing needs for freight transportation at existing level of auto mobilization are accompanied by a number of problems. Lack of a route network and information support about traffic conditions for movement of Lorries involves negative influence on social and economic development of the cities and the country as a whole. Owing to growing load of the highways, increasing intensity of freight automobile transportation in the conditions of the modern large cities megalopolises need of planning and regulation of transport streams sharply is felt. For ensuring comfort to participants of traffic and their informing on a condition of a transport network, for decrease in material and financial expenses the control systems of the traffic which have received the name Intellectual Transport Systems were created.
