Abstract
Summary. Practicability of granular mixes of iron tailings treated with cement and complex additives (basalt fiber and cationic latex) application for construction of road pavements has been studied by the results of experimental research of compressive strength, splitting strength, maximum structural strength and temperature crack-resistance index. Simultaneous application of basalt fiber and cationic latex to the composition of granular mix of iron tailings treated with cement has been found to increase compressive strength and splitting strength. It was proved that the material modified with basalt fiber and cationic latex had lower structural defect index compared to the material treated with cement only. Addition of basalt fiber to granular mix from iron tailings treated with cement or both basalt fiber and cationic latex results in higher crack-resistance as indicated by increase of the maximum structural strength and the temperature crack-resistance index. Keywords: granular mix, cationic aqueous latex, basalt fiber, iron tailings, compressive strength, splitting strength, structural defect index, maximum structural strength, temperature crack-resistance index.
