Ասֆալտբետոնե խառնուրդների բարելավում բազալտե թելիկների և ցեմենտի հավելումով

Abstract

The research presents the combined effect of basalt fibers and cement on the strength, crack resistance, and overall stability characteristics of asphalt concrete mixtures under controlled laboratory conditions. During the experiments, basalt fibers derived from locally sourced raw materials—natural basalt found within the territory of the Republic of Armenia—were utilized. In the preparation of the asphalt concrete mixtures, 20-millimeter-long basalt fibers at a dosage of 0,4 % and 4,0 % cement were added to the asphalt composition. This approach not only enables the use of local resources in the production of high-value construction materials but also ensures a significant improvement in the physico-mechanical properties of asphalt concrete mixtures. The obtained results demonstrated that the combined use of locally produced basalt fibers and cement considerably enhances the mixture’s strength and crack resistance, ensuring the high durability and long-term stability of road pavements during operation.
