Summary The climatic zone of Altai Region can be referred to as sharply continental, with the absolute air temperature maximum of +36.7C (309.7 K) and the absolute minimum of -51.5C (221.5 K). To constructions of highway engineering in Altai Region, requirements for high reliability and durability are set. They can be effectively met through the use of steel fiber concrete (SFC). SFC is a composite material which has better physical and mechanical properties compared to the traditional concrete and ferroconcrete. Conducted by Russian and foreign scientists, research work on the properties of SFC, as well as results of the authors' experimental and theoretical research on the SFC atmospheric resistance have led to the conclusion that it is expedient to use SFC in the constructions for highway engineering. Laboratory research, experimental construction of installations in Altai Region and their operation for over 15 years testify high technical and economic efficiency of SFC application in highway engineering.
Keywords steel fiber, concrete jig, steel fiber concrete, sharply continental climate, constructions for highway engineering, atmospheric resistance, durability, technical economic efficiency.
