Geoecoprotective Screens for Road Construction and Operation in Cold Regions

The intensive development of highways leads to the natural system pollution by hazardous substances such as heavy metals and oil products. At the same time, wastes are accumulated and stored in the metallurgical industry, which has a negative impact on environment. The purpose of the work is to study the applicability of the metallurgy waste for transport construction to minimize the negative impact of polluted roads on the environment in cold regions. The task of the work is using of the metallurgical wastes properties in geoecoprotective technological solutions in road construction and operation. Blast-furnace metallurgical slag was chosen as the object of study. IR spectrometry, atomic absorption photometry, and PQ analysis methods were used to study the properties of this slag. The article presents data on the degree of road pollution and on geoecoprotective capacity of blast-furnace metallurgical slag against heavy metal ions. The authors have proposed the technological solutions for using of blast-furnace metallurgical slag in transport construction and reconstruction, including the effective life calculation during their operation. There are two geoecological problems being solved for cold regions: utilization of metallurgical wastes and the use these wastes for soil cleanup and treatment of runoff containing heavy metal ions.
