Measurements of the small-dispersed dust concentration on 50 roads intersections in morning and evening, in winter and spring periods in the Volgograd city. A comparative analysis of the small-dispersed dust concentration in morning and evening is carried out, and the results, obtained in winter and spring, are compared. Methods to reduce dust emission from the roadway are proposed.

Was researched a small-dispersed dust from storage facilities in differend ranges. Was carried out acomparative analysis of the subsidence speed of the obtained particle sizes. The laboratory installation was upgraded and was installed the automatic sample dumping, and video recorder with the possibility of enlarging the image and manual focusing. Due to implementation of additional elements in the design of the installation, it was possible to exclude mechanical interference and simplify the design of the equipment. At the same time, it was possible to minimize coverage error during the experiment. The mainaim was to determine the dispersal composition with a recording on video equipment with subsequent processing of the obtained data.
