By this graph it can be concluded that with decreasing ambient temperature of -10of -20

(sample weight compactor humidity equal to 17,5% and corresponds to the natural moisture content

for the type of soil), the increase of time freezing, increases the duration of exposure to the con-

verter for the separation of the sample from the simulator. This fact is caused by the fact that at

temperatures below freezing during the freezing water in the soil sample is directly proportional to a

decrease in ambient temperature.

Technical machine performance with the device intensifying action to reduce adhesion of

soils when working in wet soils at subzero temperatures in 1,2…1,4 times higher [6], than the exca-

vators are not equipped with such device, i.e. the economic impact of their implementation due to

increased productivity. Therefore, we can talk about the feasibility of the use of piezoceramic emit-

ters to reduce adhesion soil to working bodies of earth-moving machines.
