| 英文摘要 | Desert sand is subject to deflation, which during the construction and operation of railways in the sandy desert leads to the filling of the railway track with sand and erosion of subgrade. To prevent this phenomenon, the surface of the sand is fixed with a binder, which is sprayed onto a deflated surface. The penetration of the working composition of the binder due to the characteristics of grinding is accompanied by an uneven distribution of the substance, which is proposed to characterize the saturation coefficient. Peculiarities of the interaction of the binder and sand from which the protective crust is formed are revealed, which made it possible to change the nature of the impregnation. Pre-wetting allows to reduce the pore space of sand, change the nature of the transfer of the substance when impregnated into the capillary, and increase the uniformity of impregnation, which as a result allows to obtain a resource-saving solution when fixing the movement of sand. |
