Abstract:
Nowadays, due to the increase in the amount of traffic and the number of axles, the use of additives in asphalt concrete has become common. In recent decades, one of the goals of engineers in asphalt technology has been to increase the bearing capacity and improve the tensile strength of asphalt mixtures. One of these effective additives in this matter is fiber. Fibers mainly contribute to the reinforcement of asphalt mixtures. Accordingly, in this research, the properties of asphalt mixtures reinforced with ۵-component fibers and glass fibers have been investigated. ۵-component fibers areadded in ۰.۰۵, ۰.۰۷۵ and ۰.۰۱% of the weight of stone materials and glass fibers are added in ۰.۱, ۰.۲ and ۰.۳% of the weight of stone materials in asphalt mixtures and finally based on performance characteristics including Marshall resistance, indirect tension, moisture sensitivity, dynamic creep and resilient modulus are the most optimal among the above percentages. According to the results of this research, ۵-component fibers have the best results in many of the mentioned characteristics at ۰.۰۷۵ percent and glass fibers at ۰.۲ percent.
