Abstract: The article analyzes the effective methods of dispersed reinforcement of road asphalt concrete mixtures taking into account the properties of reinforcing polymer fibers in the countries of the European Union, the United States of America, Canada and the Russian Federation. The disadvantages and advantages of the existing methods of dispersed reinforcement of asphalt concrete mixtures are indicated. It is shown that, for example, for the most uniform distribution of polypropylene fibers, it is advisable to introduce fibers into a mixer with a ready-made asphalt concrete mixture for 5–10 seconds. A comparative analysis of the physical and mechanical properties of the most common types of fibers: polypropylene, polyethylene terephthalate, and glass fiber has been carried out. It has been established that dispersed reinforcement of asphalt concrete with fiberglass makes it possible to increase fatigue life by 40…50 % when exposed to large standard loads.
Keywords: asphalt concrete, synthetic fibers, glass fiber, polypropylene fiber, polyethylene terephthalate fiber, methods of dispersed reinforcement.
