In article results of pilot studies according to influence of dust emissions in the atmosphere from sources of asphalt concrete plants on concentration and fractional composition of dust are given in atmospheric air. The obtained data testify to insufficient efficiency of actions for decrease in the pylevydeleniye in environment applied now at the considered enterprises. The assessment of necessary fractional efficiency of a pyleulavlivaniye in the conditions of the operating production is carried out.
