The problem of gravel road dustiness is quite acute. In order to minimize harmful environmental components and to conduct dust reduction tests, molasses materials were chosen. Using the molasses materials of a new generation (solution Safecote) in the Lithuanian market, the obtained results of dustiness have reflected a reduction in particulate matter in the air. During the experiment, gravel road pavement was treated with different degrees of concentration (10%, 20%, 30%) in solution “Safecote” at a driving speed of 30 km/h. Dustiness was measured at different distances from the road (0 m, 1 m, 2 m, 3 m). The undertaken study showed that the concentrations of particulate matter varied under changing weather conditions (air temperature, humidity, wind speed, atmospheric pressure). The statistical analysis of the received data has revealed that dustiness weakly correlates with temperature (correlation coefficient ranged from 0.12 to 0.67) moving from the road, the correlation coefficient of moisture is negative, a larger distance from the road increases inverse correlation (the correlation coefficient ranges from –0.02 to –0.85), negative correlation decreases moving from the road at a speed of the wind (from –0.72 to –0.06) and pressure correlation remains volatile (from –0.44 to 0.44).
