Summary: The negative seasonality impact on logging processes and the predominant use of snow and ice roads necessitate year-round logging roads engagement and provision the industry with high-quality road construction materials. The aim of the work was to study and comparatively evaluate the filtration properties of natural and granite crushing sand. The materials for the study were samples of natural sand and granite crushing sand from Karelian deposits with a size of 0—5 mm. During the study the following parameters were assessed and their influence on filtration properties was identified: mineral and granulometric composition, fineness modulus, dust particle content, homogeneity, flakiness, and voidness. The dependences of the filtration coefficient on the fineness modulus for natural sand and the continuous dependence of the filtration coefficient for all studied samples on the content of dust particles with a size of less than 0.05 mm were determined. The authors established that the natural sand filtration properties outmatch those of granite crushed sand. Granite crushed sand is an artificial material formed as a result of the technological crushing process. During crushing the amount of dust particles, flakiness index, voidness increases and the heterogeneity of the crushed sand samples increases. The crushing process has both a direct and indirect effect on the filtration coefficient. |
